624ZZ (4x13x5) Deep Groove Ball Bearing, Miniature Bearing

624ZZ Ball Bearing — 4x13x5mm

The 624ZZ is a miniature deep-groove ball bearing with a 4mm bore, 13mm outer diameter, and 5mm 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 well suited for micro robotics, small drone components, and precision instruments needing reliable rotation on a 4mm shaft.
