Komatsu 561-40-61260 | Heavy-Duty Spherical Plain Bearing for Mining Dump Trucks

The 561-40-61260 Spherical Plain Bearing / Bushing is an OEM-standard replacement component engineered specifically for high-load articulating joints on heavy Komatsu machinery. Precision-manufactured from high-grade alloy steel, this spherical bushing is designed to accommodate angular misalignment, high radial stress, and heavy multi-directional shock loads inherent in heavy mining and quarry hauling operations.

Equipped with an integrated lubrication groove, grease port, and high-performance sealing rings, this bearing reduces friction, prevents contamination from dust and debris, and delivers long operational life under demanding field conditions. It is engineered to restore factory tolerances in steering, suspension linkage, and front axle lever assemblies—minimizing downtime and protecting critical structural pins from premature wear.
