MR106 is a metric size miniature deep groove ball bearing with a dimension of 6x10x2.5 mm. Its bore diameter is 6 mm, outer diameter is 10 mm, and thickness is 2.5 mm. It is an ABEC-1 grade ball bearing, the tolerance of bore and outer diameter is -0.008 to 0 mm, and the tolerance of width is -0.12 to 0 mm. Its radial clearance is 0.002 to 0.013 mm, which it is MC3 grade. If you want double shielded miniature ball bearing the same sizes bore and outer diameter as MR106, you can check MR106ZZ bearing. However, the width of MR106ZZ is 3 mm not 2.5 mm as MR106.

MR106 bearing can bear a dynamic radial load of 422 Newton, and a static radial load of 174 Newton. Lubrication is required, and with the oil lubricating its rotating max speed can reach up to 45,000 rpm. It is suitable to work in a temperature condition between -30℃ to 110℃.

With its very small sizes, high speed but lower load, MR106 bearing is widely used in applications like precision instruments and micro motors, etc. Fitrun Bearing is a professional manufacturer of miniature ball bearings with 20 years bearing manufacturing experience.
