Product Description

The 627 ZZ is a high-performance, double-shielded deep groove ball bearing specifically engineered for fan motor applications. With optimized 7×22×7 mm (ID×OD×W) dimensions, this bearing delivers ultra-long service life (50,000+ hours) under continuous operation in HVAC systems, cooling fans, and industrial blowers.

Featuring dual metal shields (ZZ) for superior dust protection and ABEC-3 precision, it ensures low vibration and quiet operation – critical for noise-sensitive environments. The high-grade chrome steel construction with special C3 internal clearance accommodates thermal expansion in high-temperature fan applications.
