Other driveline components from PTC Drivelines that pair with this spider assembly on the Wheel Nut .
Wheel Nut, otherwise referred to as Lug Nut, Rim Nut, Wheel Flange Nut, or HEX Nut, is a high-tensile fastened component that is used to affix the rim of the wheel to the hub. Wheel Nuts usually consist of a screw, however, some types of fastening wheels need the use of a wheel bolt. There is variation in the design and thread specifications of the wheel nut based on the type of vehicle or equipment.
In order to suit the demands of heavy-duty use, different types of wheel nuts are used by different types of equipment. While certain models of the Komatsu HD785-7, HD785-5, and HD785-2 have specific wheel assemblies that require the use of the 569-22-72870 wheel nut, certain BEML BH35-2 and BH50M have various other specific standard flange nuts. It is known that the use of a BEML wheel nut is beneficial as it contains an integrated flange, thus increasing the bearing surface for the rim mounting area.
PTC Driveline is a Wheel Nut Manufacturers in Tanzania. Our wheel nuts are available in different design, including HEX Wheel Nuts and Flanger Wheel Nuts, according to specific equipment and other applications.
PTC Driveline is a Wheel Nut Supplier in Tanzania that provides Wheel Nuts for repair and quantity needs for heavy-duty equipment fleets and equipment maintenance purposes. We supply compatible Wheel Nuts for Komatsu HD785-7, HD785-5, HD785-2, BEML BH35-2, BH50M applications and other types of devices. Customers may provide the OEM part number, model of device, or details of existing parts to determine the correct Wheel Nut for the given purpose.
The principal role of a Wheel Nut is to produce the required clamping force keeping the wheel rim firmly against the hub or the wheel mounting surface. When several Wheel Nuts are installed properly tight and meet the specified torque, they function together to keep the wheel assembly positioned as required in the conditions of load and movement.
Wheel Nuts can be considered critical safety fasteners especially in the case of heavy-duty machinery operating under significant load and dynamic impact. Not enough tightening results in movement of the wheel and the surfaces it is mounted on and is likely to cause fretting and loosening over time. On the contrary, excessive tightening may potentially lead to overloading and damage of the fastening components. Therefore, the correct installation entails proper following of the OEM torque specifications and using accurate torque equipment.
Wheel Nuts are critical parts used to install Wheel Assembly by ensuring required degree of clamping action between the wheel rim and hub. Fastening elements comprise wheel nut, wheel stud, rim seating surface, and hub. Safe connection involves proper engagement of threads, adequate strength of the construction, and the required value of tightening torque.
In the case of fasteners used in heavy-duty applications, Wheel Nuts can be made of high-strength materials such as materials with characteristics of Grade 12.9 materials according to specifications. The part may have certain characteristics including the thread pitch and tolerance according to OEM standards, dimension compatibility, and any special coating such as black phosphate. Different types of quality assurance such as hardness tests and other papers may be applied for fasteners.
Wheel Nuts are available in different designs based on the wheel mounting arrangement, load requirements, seating configuration, and equipment application. The correct type should be selected according to the Wheel Stud specifications, rim design, hub assembly, OEM requirements, and operating conditions.
Heavy Duty Wheel Nuts are created for uses that involve considerable vehicle loads, vibration, multiple operational stresses, and difficult working situations. They can be applied in mining dump trucks, construction machines, earthmoving equipment, and other heavy-duty vehicles. Depending on the use, the nuts can be manufactured from high-strength steel according to required thread parameters, strength parameters, and OEM specifications.
Hex Wheel Nuts have six sides, which can be adjusted and removed with the help of a corresponding wrench or socket. They are widely used in many applications of wheel fastening and can be produced in numerous sizes, dimensions, and material grades. In the case of the Komatsu HD785-7, HD785-5, and HD785-2 wheel assemblies, the 569-22-72870 HEX Wheel Nut is suggested according to relevant equipment and OEM Part Number specifications.
Flange Wheel Nuts have a flange as an integral part of the nut body, which provides a wider bearing surface against the wheel and rim. This design allows spreading the clamping force over a bigger contact surface. For the BEML BH35-2 and BH50M applications, the TW1745 Flange Nut is suggested in line with the relevant wheel assembly specifications.
The design of Conical Seat Wheel Nuts involves a tapered seating surface such that they fit into a compatible conical recess in the wheel. When Conical Wheel Nuts are applied, these surfaces come into contact, ensuring the proper centering and clamping of the wheel. What is necessary is that the angle of the taper as well as its dimensions match the design of the wheel for its proper engagement and fitting.
Flat Seat Wheel Nuts are designed with a flat contact surface suitable for the mating applications with a similar flat mounting surface. In certain applications a washer or an additional seating device may also be included in the fastening process. The seating dimensions and compatibility of the surface are very important to reach the necessary clamping force.
Two-Piece Wheel Nuts are usually composed of a regular nut body with a separate washer or seating part. This design makes it possible for the nut to spin during the tightening process without causing any movement of the seating surface and the wheel. Their design and application depend on the specific mounting system and the requirements of the original equipment manufacturer.
OEM Wheel Nuts are defined by the specifications set by the original equipment manufacturer along with the Part Numbers. Aftermarket wheel nuts are the parts created to fulfill specifications including dimensions, thread, material, and application. It is important to check for compatibility of the selected OEM-reference or aftermarket wheel nut with the equipment model, Wheel Stud, thread pitch, seat shape, and necessary strength requirements before its installation.
PTC Driveline is also a Wheel Nut Exporter from Tanzania, supplying heavy-duty wheel fastening components for international replacement and industrial requirements. Wheel Nuts can be supplied according to required OEM references, thread dimensions, seating configurations, material specifications, and application requirements. Our supply capabilities support standard and application-specific Wheel Nut requirements for customers looking for reliable heavy-equipment fastening components from Tanzania.
Heavy duty wheel nuts are used in mining dump trucks and other heavy machines, where wheel assemblies bear heavy loads, experience vibrations and are subjected to harsh working conditions. The choice of the right wheel nut depends on the model of the equipment, the place of the wheel and the specifications of the thread and seating design as well as the OEM part number.
The HEX Wheel Nut marked as 569-22-72870 is designed for use on the Komatsu HD785-7 and HD785-5 wheel assemblies. It has been one of the most required replacement Wheel Nuts for the heavy-duty mining dump trucks. Wheel Nuts can be made available in bulk, as per fleet maintenance and replacement needs as well as by customizing to meet the OEM reference and equipment specifications.
The 569-22-72870 Wheel Nut is utilized in various Komatsu HD785-2 configurations, so it is important to know the part number and details of the wheel assembly before ordering a replacement.
The TW1745 Flange Wheel Nut is commonly used in BEML BH35-2 and BH50M wheel assemblies, since its integrated flange offers a larger bearing area as compared to standard HEX Wheel Nuts, thus making it helpful in transferring the holding load over the wheel mounting area in the most effective manner. This type of wheel fastening is widely used in the mining sector.
Wheel Nuts are important maintenance components for heavy machinery fleets. Keeping an adequate stock of replacement supplies is important for carrying out scheduled maintenance and to limit delays arising from components not being available. PTC Driveline can provide large quantities of Wheel Nuts in units of 100 or more so fleets can maintain their stock of parts within the specified parameters.
PTC Driveline will provide complete Wheel Nut and Bolt Kits with compatible items fully assembled for specific equipment use. A complete set can include wheel nuts, Bolts, Studs, Washers, etc., depending on the type of assembly. Customers will give model numbers or OEM numbers in order to identify their shipments and costs.
Wheel Nuts are also available for heavy mobile equipment such as the Komatsu HD1500 or the HD465 series, BEML models BH100, BH60, and BH40, and other different models of Caterpillar Dump Trucks. Customers will provide the necessary information such as model numbers or part numbers to have the parts identified correctly.
When fitting wheels, choosing the right Wheel Nut is a critical step to ensure correct fitment, secure wheel attachment and optimum performance for heavy duty use. The replacement Wheel Nut should be chosen according to the exact model of the equipment, Wheel Stud compatibility, thread specifications, strength, and OEM Part Number. Looks might deceive, but a Wheel Nut that seems to be the same does not always have the same technical data and should not be used without checking compatibility.
Check the exact make, model and wheel assembly of the equipment. Wheel Nut requirements may vary from model to model and even from generation to generation within the same model. For instance, the 569-22-72870 HEX Wheel Nut applies to applicable Komatsu HD785-7, HD785-5, and HD785-2 applications and the TW1745 Flange Wheel Nut applies to applicable BEML BH35-2 & BH50M wheel assemblies. Please double-check the application before placing the order.
The internal thread of the Wheel Nut should match the external thread of the Wheel Stud. The type, diameter and pitch of the thread must be suitable, and the engagement must meet the requirements. If a mismatched Wheel Nut is used, it can strip the threads, cause an incorrect fit and impact the clamping ability of the wheel fastening assembly.
Verify the required thread size and size of the threads with the original part or OEM's specification. Wheel Nuts can have different thread configurations if they are the same outer size. Using a wrong thread can cause cross-threading, damage to the thread, poor engagement or trouble getting the correct tighten condition.
The seating pattern should be the same as the wheel or rim configuration it is to be fitted to. The assembly can be a HEX Wheel Nut, Flange Wheel Nut, Conical Seat Wheel Nut or Flat Seat Wheel Nut depending on the application. The TW1745 Flange Wheel Nut is an integral flange with a wider bearing surface for the applicable BEML wheel assembly for example. The following can be impacted by an incorrect seating profile: contact, load distribution, wheel clamping.
Wheel Nuts in heavy duty trucks such as mining dump trucks can have to withstand a significant amount of load, vibration, impact and repeated dynamic loads. The chosen component should be compatible with the desired application and its material and strength requirements. Consideration should be given to equipment load, operating environment, duty cycle and vibration levels when choosing a replacement Wheel Nut.
One of the best ways to ensure you order the right replacement Wheel Nut is to match the OEM Part Number. OEM references can be used to confirm design and application compatibility. Prior to ordering, please cross reference the Part Number with the equipment model and corresponding wheel assembly for the correct Wheel Nut that is meeting the specification.
Wheel Nut failure may be caused by improper installation, misuse or incorrect torque application, incompatible fastening parts, excessive operating loads, or prolonged exposure to environmental conditions. Wheel fastening components in heavy-duty mining and construction equipment are subjected to high loads, vibrations, and stress. It is crucial to know the cause of the damage to ensure that a problem will not be repeated, and to keep the wheel assembly in good condition.
Wheel Nuts should be torqued to the torque recommended for the assembly and equipment in question. Wrong torque can cause a lack of clamping force or overclamping. For the application of safety critical wheel fastening, the procedure recommended by the manufacturer and appropriate calibrated tools must be used.
Excessive torque will overstress the Wheel Nut, the Wheel Stud and/or the fastening arrangement, which could lead to damage of the threads or deformation of the Wheel Nut and/or the Wheel Stud and/or the fastening arrangement. Too tight could also damage the wheel seat area. Do not re-use a damaged Wheel Nut or Stud.
If the clamp is not tightened enough, there may be an inadequate clamping force between the wheel rim and the hub. This can allow relative movement within the wheel assembly that can lead to fretting, progressive loosening and damage to the Wheel Stud or mounting surfaces. Therefore, it is necessary to tighten Wheel Nuts to the specified requirements and to perform inspection in accordance with the relevant maintenance procedures.
The dimension of the threads in the Wheel Nut must be identical to that of the Wheel Stud and must be the same length and pitch. If the parts are not compatible with one another, they can be cross-threaded, thread engagement is not great, or damage may be caused during installation. The seating arrangement for the Wheel Nut should also correspond to that of the wheel assembly, such as designing a HEX, Flange, Conical Seat or any other type of seat specified.
High loads and impact, combined with constant vibration, are a significant challenge for heavy-duty equipment used in mining, construction or earthmoving applications. These can be conditions that will put on repeated stresses on the wheel fastening system. The risk of wear, deformation, or early failure increases if a Wheel Nut is used with material or strength specifications, or application, that are inappropriate.
Corrosion and surface deterioration can occur over time due to moisture, dust, chemicals, and harsh environments. The Wheel Nut can suffer from threads, seating surface and mechanical integrity issues due to severe corrosion. Careful surface treatment, such as phosphate coating as indicated, can enhance surface protection but if the surface is seriously corroded or damaged, it should be replaced.
