PTC-1019 Spider Assembly (OEM: HM 81805356 / 81019082 )is a heavy-duty universal joint cross assembly used in heavy machinery drivelines, designed for dump trucks and haul trucks. This spider assembly is fitted to the driveshaft / propeller shaft assembly, where it transmits engine torque through the axle universal joint, and is compatible with HM 1035 dump trucks.

Built from high-grade alloy steel forgings, the PTC-1019 spider assembly delivers superior fatigue strength and impact resistance for demanding mining and earthmoving duty cycles. The trunnion journals are precision-ground and hardened to withstand continuous high-torque loading in heavy-duty off-highway applications. Each unit is dimensionally matched to OEM specifications, ensuring direct drop-in fitment with no equipment modification required, and a full quality inspection report is available on request.
