FAQ
Q1: What is the advantage of hybrid ceramic bearings compared to steel bearings?

Hybrid ceramic bearings use ceramic balls and steel rings, providing lower friction, higher speed capability, and longer service life than conventional steel bearings.

Q2: Can you provide ABEC 7 precision grade for SR188 bearings?

Yes. We offer ABEC 1, ABEC 3, ABEC 5, and ABEC 7 precision grades depending on appliion requirements.

Q3: Are sealed versions available for dust or moisture protection?

Yes. SR188 bearings can be supplied with metal shields (ZZ) or rubber seals (2RS) for improved contamination protection.
