F626 ZZ MGK 6x19x6 Flanged Ball Bearing - Miniature, Shielded

Technical Specifications and Applications of the F626 ZZ MGK Flanged Bearing

Product Overview

The F626 ZZ MGK 6x19x6 flanged ball bearing is a miniature deep groove bearing with a flange (F) and double metal shields (ZZ). The flange ensures stable mounting in cylindrical housings, preventing axial displacement, while the metal shields protect the rolling elements from dust and contaminants. Compact, lightweight, and factory-lubricated, it is designed for high-speed, low-friction operation in precision applications.
