Key Features of Precision Bearings

High Accuracy

These bearings are engineered to very tight tolerances to ensure minimal runout and consistent motion. The precision of the bearing is specified by the progressive number in a bearings tolerance class. For ISO standards, the higher the number the higher the bearing precision. However, with DIN standards the lower the number the higher the bearing precision.

Durability

Precision bearings are made from high-grade materials with advanced heat treatments and coatings for wear resistance. They are designed to withstand harsh environments including high speed, loads, and temperatures.

Low friction and smooth operation

These bearings are optimised to reduce vibrations and noise beyond standard bearings

Types of Precision Bearings:
