The 561-22-61960 tapered roller bearing is specially designed for heavy Komatsu mining dump trucks HD785-7 and HD985 with fully OEM-compliant dimensions. It is mounted on key transmission positions such as axles and final drives, enduring alternating impact loads from heavy mining haulage. With high load strength, it acts as a cost-effective OEM substitute for truck axle repair and replacement.
Made of standard GCr15 high-carbon chromium bearing steel with precise quenching and tempering treatment, it features uniform hardness and stable metallographic structure for long anti-fatigue and wear life. The tapered raceway distributes radial and axial thrust efficiently to fit frequent start-stop operation and rough mine roads. Split inner and outer rings simplify disassembly to cut maintenance downtime and haulage losses, while finely finished raceways reduce friction heat during operation.
Manufactured strictly to original 561-22-61960 specifications for direct replacement without secondary machining. Full inspection on clearance, hardness and appearance is completed before delivery. Custom precision grades are available for bulk orders. Proper preload clearance during installation helps extend bearing service life.
Widely used for overhaul of Komatsu HD785-7/HD985 dump trucks, export wholesale of mining machinery spare parts, regular maintenance of large mining haulage fleets, solving common defects including abnormal noise, looseness, uneven wear, transmission shake and load degradation of original bearings.
