627ZZ (7x22x7) Deep Groove Ball Bearing, Miniature Bearing

627ZZ Ball Bearing — 7x22x7mm

The 627ZZ is a miniature deep-groove ball bearing with a 7mm bore, 22mm outer diameter, and 7mm width. Fitted with double metal shields (ZZ), it keeps dust and debris out while retaining lubrication, making it a reliable, low-maintenance choice for small-scale rotating assemblies.

Its compact size and smooth, low-friction rotation make it a solid choice for robotics, small drone components, and precision instruments needing reliable rotation on a 7mm shaft.
