Rolling bearings: why raceway grinding + honing determine quality

In rolling bearing manufacturing, the raceway is the functional core. Its surface quality significantly influences noise behavior, friction, and service life.

Grinding defines the geometry. Honing optimizes the surface. Raceway grinding produces dimensional accuracy and roundness. The subsequent honing improves the microstructure, reduces roughness peaks, and ensures an even load distribution.

In many applications, this leads to:

• quieter running behavior
• lower friction and noise generation
• increased fatigue strength of the raceway

A matched grinding and honing tool system is decisive – adapted to the material, process step, and series requirement.

This is exactly where specialized tools for the bearing industry come in.
