56425/56650 Heavy-Duty Imperial Tapered Roller Bearing

Exceptional Payload Support: Built to absorb massive radial loads and severe axial cornering forces in heavy vehicles.
Case-Hardened Durability: Deep heat treatment ensures a tough core to resist sudden shock impacts.
Separable Construction: Outer cup and inner cone can be mounted independently for efficient assembly line integration.
Optimized Surface Finish: Micro-honed raceways lower operational temperatures and reduce friction-induced power loss.
