  • Bearing Tolerances and Precision Levels | AST Bearings

    While all bearings are extremely precise mechanisms, a designer must consider the benefits of tighter tolerances in terms of performance and bearing life. For example, there is a direct correlation with precision class and bearing life. Raceway parallelism, a feature controlled by ABEC, can impact bearing torque.

  • Corrotect Corrosion Protection

    martensitic, bainitic or case hardened rolling bearing steels 100Cr6. If standard rolling bearing steels come into contact with water or humidity, however, they can undergo corrosion, which can cause a permanent impairment of the intended function. Corrosion-resistant rolling bearing steels provide a remedy here but are expensive.
