Precision Skf needle bearing raceway

Practical benefits

Hardened raceway for shafts: You obtain a smooth bearing surface when the machine shaft cannot be hardened or ground.
Smooth dual axial displacement: The design accommodates axial movement in both directions without causing unnecessary mechanical wear.
Fully interchangeable component fit: You can easily swap components during maintenance thanks to standard precision manufacturing dimensions.

In a nutshell

The right choise for

With the Skf ir 70X80X25, you create a hardened raceway for needle roller bearings when the machine shaft cannot be hardened or ground. This precision inner ring prevents direct wear and scoring on the shaft surface, allowing you to quickly replace the bearing contact surface without machining or replacing the entire shaft. The design smoothly accommodates axial displacement in both directions during demanding industrial operation. Thanks to standardized dimensions of 70 x 80 x 25 mm, you benefit from a precise fit and complete interchangeability in gearboxes and drive assemblies.
