FAQ - Frequently Asked Questions

1. What does “ZZ” stand for?
It refers to metal shields on both sides of the bearing, protecting internal components from contamination.

2. What is “C3 clearance”?
Indicates an internal clearance greater than standard, suitable for applications with temperature-induced expansion.

3. Is the bearing pre-lubricated?
Yes, factory-lubricated and designed for hassle-free operation.

4. Typical applications?
Used widely in high-speed machinery, motors, industrial gear units, and equipment subject to thermal fluctuations.

5. How does it compare to sealed types?
Metal shields enable better heat dissipation and performance under high speeds compared to rubber-sealed options.
