Komatsu 569-52-41920 Bushing | Heavy-Duty Suspension & Axle Plain Bearing

Engineered for severe duty cycles and maximum service life, the Komatsu 569-52-41920 Bushing is an OEM-standard replacement component designed for Komatsu rigid dump trucks. Built to absorb high radial and axial dynamic loads, this precision-machined spherical plain bushing serves critical articulation points across suspension cylinder mountings, front axle levers, and rear axle support assemblies.

Manufactured from high-grade, heat-treated alloy bearing steel, the bushing features case-hardened wear surfaces ground to micro-tolerances. This composition delivers exceptional galling resistance, low frictional torque, and prolonged durability under heavy shock loading and continuous high-tonnage hauling. The assembly integrates dual radial sealing rings to lock in lubrication while preventing abrasive contaminants, mine dust, and moisture from penetrating the raceway. Featuring integrated oil feed holes and distribution grooves, this component ensures efficient lubricant dispersal to reduce downtime, eliminate premature pin wear, and maintain peak fleet availability in open-pit mining, quarrying, and bulk earthmoving environments.
