Reliable raceway performance with Skf

Practical benefits

Hardened precision raceway surface: You obtain a precision ground raceway on shafts that cannot be directly hardened and ground.
Accommodates bidirectional axial movement: The design allows axial displacement in both directions smoothly during continuous rotational operation.
Seamless component interchangeability: Standardized manufacturing enables you to replace worn bearing rings quickly without modifying surrounding parts.

In a nutshell

The right choise for

When your shaft cannot be hardened and ground, the Skf ir 50X55X25 inner ring provides a precision-machined, hardened raceway for needle roller bearing assemblies. Designed for the ir series, it protects shafts from premature wear and damage in gearboxes, pumps, and rotating machinery. Featuring a 50 mm inside diameter, 55 mm outside diameter, and 25 mm width, the running surface smoothly accommodates bidirectional axial displacement during heavy rotational operation. This allows you to replace worn raceways quickly during maintenance and overhaul tasks without having to rework or replace the complete shaft.
