628ZZ (8x24x8) Deep Groove Ball Bearing, Miniature Bearing

628ZZ Ball Bearing — 8x24x8mm

The 628ZZ is a miniature deep-groove ball bearing with an 8mm bore, 24mm outer diameter, and 8mm 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 an 8mm shaft — a slightly wider alternative to the more common 608ZZ where extra load capacity or axial stability is needed.
