Metric Size Standard Miniature Ball Bearings MR106

Metric Size Standard Miniature Ball Bearings MR106

The MR106 is a compact miniature ball bearing with a 6mm bore and 10mm outer diameter, measuring just 2.5mm wide. Made from chrome steel, it’s built to handle radial loads up to 95 lbf while spinning smoothly at speeds up to 45,000 RPM.

Its open design allows for easy lubrication, and the stainless steel cage ensures durability. With a radial clearance of 0.002mm to 0.013mm, it offers smooth operation for precision applications.

This bearing is ideal for small devices like model motors or precision instruments where space is limited. It works well in temperatures from -30°C to 110°C and complies with RoHS and REACH standards.

Weighing only 0.55g, it’s lightweight yet robust for its size, making it a practical choice for compact machinery.
