Reliable raceway for needle bearings

Practical benefits

Hardened surface for shafts: You obtain a precision raceway for applications where the shaft cannot be hardened and ground.
Smooth bidirectional axial displacement: The Skf inner ring accommodates axial movement in both directions to ensure smooth mechanical operation.
Standardized dimensional accuracy: Precision dimensions of 45 x 50 x 25 mm allow complete interchangeability within compact needle roller assemblies.

In a nutshell

The right choise for

With the Skf ir 45X50X25 inner ring, you provide a precision-ground and hardened raceway for needle roller bearings on shafts that cannot be hardened and ground. This prevents direct shaft wear and premature bearing failure during mechanical overhaul of rotating equipment, gearboxes, and drivetrains. Featuring an inside diameter of 45 mm, an outside diameter of 50 mm, and a width of 25 mm, it accommodates axial displacement in both directions. You can easily combine it with needle roller assemblies and restore worn raceway surfaces without replacing the entire shaft.
