High-Quality Replacement Driveline Parts by — PTC Drivelines
Other driveline components from PTC Drivelines that pair with this spider assembly on the Spider Assembly.
PTC Drivelines is a trusted Spider Assembly Suppliers in Nairobi, supplying heavy-duty spider assemblies to mining, construction, earthmoving, and commercial vehicle operators across Nairobi. Every UJ cross we build is engineered to OEM-compatible dimensions, giving customers a dependable universal joint component for reliable torque transmission and driveline articulation.
As a spider assembly supplier India, we precision-engineer UJ crosses that deliver consistent torque transmission and angular movement in demanding driveline systems. Our range is built to replace Komatsu, BEML, CAT, Volvo, SDLG, and other heavy equipment OEM parts, giving buyers in Nairobi a reliable, application-matched alternative.
Every spider assembly is defined by a set of critical parameters—journal diameter, cup bore, cross geometry, surface finish, and journal hardness. By working from OEM cross-referenced dimensions and deep application knowledge, PTC Drivelines minimizes compatibility issues and keeps driveline operations running smoothly across Nairobi.
A spider assembly—also called a UJ cross, universal joint cross, or cross journal—is the forged-steel, cross-shaped part at the center of a universal joint. It carries four journal pins, each fitted with a needle roller bearing cup, allowing two shafts running at an angle to transmit torque smoothly.
Spider assemblies typically sit at the end of a propeller shaft in heavy-duty vehicles and equipment, connecting the gearbox output yoke to the driveshaft and the driveshaft to the axle input flange and differential. Depending on driveline configuration, heavy trucks and mining equipment can carry anywhere from two to six spider assemblies.
In harsh mining and industrial environments, conventionally greased UJ crosses often fail early. Abrasive dust and silica ingress, water exposure, inconsistent greasing schedules, and grease loss from centrifugal force during operation all contaminate the bearing area and accelerate wear. In critical mining applications, this turns traditional greased spider assemblies into a recurring—and costly—maintenance burden.
We are the reputable Spider Assembly Manufacturers in Nairobi. But PTC Drivelines focuses specifically on robust UJ cross assemblies built for extreme mining and industrial driveline duty. The spider assembly—also known as a cross journal, cross bearing kit, or universal joint cross—is the forged-steel, cross-shaped component at the heart of every universal joint. We are the best when it comes to spider assembly manufacturer India.
Four journal pins and needle roller bearing cups hold the assembly together, allowing torque to transfer smoothly even when the connecting shafts operate at an angle. Spider assemblies are typically used to connect the propeller shaft to the gearbox output yoke and the driveshaft to the differential or axle input flange in heavy equipment.
Our manufacturing process centers on OEM dimensional accuracy, precision machining, careful material selection, and thorough dimensional inspection. Every critical feature—journal diameter, cup bore, cross geometry, surface finish, and hardness—is checked to support true direct replacement.
To address this, PTC Drivelines offers a sealed self-lubricated spider assembly built around a three-stage sealing architecture that protects the internal bearing environment. An outer lip seal, an intermediate labyrinth seal, and an inner retention seal work together as multiple layers of defense against contamination while keeping lubricant locked inside the bearing zone.
Built as a drop-in replacement for applications with OEM-comparable dimensions, this maintenance free spider assembly India is designed to cut down on lubrication-related upkeep. It's engineered for tough-duty mining, earthmoving, and heavy-duty driveline applications, where dust, water, vibration, and constant torque transfer wear down conventional universal joints.
These are some of the benefits of the 3-stage sealed spider assembly:
The right spider assembly depends on equipment design, operating conditions, and universal joint dimensions.

Key applications include:
As a UJ cross manufacturer India, PTC Drivelines supports a wide range of heavy equipment across mining, earthmoving, construction, and commercial-vehicle sectors:
Spider assemblies are used across heavy mining equipment in coal, iron ore, and limestone operations. This includes the Komatsu HD785 spider assembly (and the later Komatsu HD785-7 spider assembly variant) and the Komatsu HD1500 spider assembly for rigid dump trucks, as well as the BEML BH100 spider assembly, BEML BH60 spider assembly, and the CAT 770G spider bearing through CAT 793C spider bearing range.
Heavy-duty UJ cross assemblies drive wheel loaders such as the Komatsu WA470, WA500, WA600, and WA800, the CAT 988H, and select SDLG wheel loader models.
Spider assemblies support motor grader work in haul-road maintenance, surface grading, and road construction, covering equipment such as the Komatsu GD825, GD605, and CAT 14M and 120K.
High-load, low-speed applications such as berm construction, overburden removal, and ripping call for robust universal joint components—as used on the Komatsu D155A, D355A, D375A, and D475A.
Multi-shaft drivelines in articulated dump trucks, such as the Komatsu HM1035, often require several spider assemblies working together across the driveline.
Spider assemblies are also widely used in construction equipment, aggregate haulage, and commercial heavy vehicles, including select CAT rigid dump trucks and Volvo heavy-duty truck applications. This makes PTC Drivelines a dependable universal joint cross manufacturer India for both mining-specific and general commercial fleets.
Conventional greased spider assemblies wear out early when exposed to abrasive dust, silica, water contamination, and inconsistent lubrication. In heavy-duty mining applications, high speeds and centrifugal force compound the problem by driving lubricant out of the bearing area.
A sealed spider assembly solves this with a multi-stage sealing system:
Together, this sealing architecture lowers contamination-related wear and cuts maintenance needs compared with conventional, lubrication-dependent universal joint designs.
