The 561-20-62100 universal joint spider bearing is customized for driveshafts of heavy Komatsu dump trucks HD785 and HD985 with fully OEM-matched dimensions and matching installation bolts. It is installed at driveshaft cross joints to transmit torque and endure alternating impact loads during start-stop and bumpy driving, acting as a cost-effective OEM substitute for routine maintenance and transmission overhaul.
It is integrally forged from high-strength bearing steel and tempered to improve overall toughness and surface hardness. Precision grinding on cross shaft working surfaces delivers outstanding wear and fatigue resistance. The integrated flange structure with matched fasteners simplifies positioning during assembly and reduces misalignment risks. Optimized sealing prevents mine dust and slurry ingress to avoid premature jamming and wear, cutting abnormal noise and loosening failures under long-term heavy mining haulage.
Manufactured strictly to original 561-20-62100 specifications with supporting fasteners for direct replacement without secondary machining. Every unit passes full inspection on dimension tolerance, hardness and fitting tolerance before delivery. Custom precision grades are available for bulk orders. Fasten bolts per OEM torque requirement during installation for even stress distribution and longer service life.
Widely applied for driveshaft repair of Komatsu HD785/HD985 dump trucks, export wholesale of mining machinery spare parts, regular maintenance of large mining haulage fleets, solving common issues such as loose joint noise, transmission shake, cross shaft wear fracture and unstable torque output.
