Metric Size Standard Miniature Ball Bearings 634zz

The 634zz is a compact metric ball bearing with a 4mm bore and 16mm outer diameter, crafted from sturdy chrome steel. Its shielded design keeps dust out while allowing smooth rotation at speeds up to 36,000 RPM.

With a dynamic radial load capacity of 256 lbf, it handles moderate forces well. The stainless steel cage and shields ensure durability in temperatures from -30°C to 110°C.

This single-row bearing is easy to install and requires lubrication for optimal performance. Its small size (5mm width) and lightweight (5.44g) make it ideal for miniature applications.

Common uses include small motors, hobby projects, or precision instruments where reliable radial support is needed. Compliant with RoHS and REACH standards for safe operation.
