Product Description

Extra Miniature Bearing

Extra-miniature bearing can greatly expand application. An abundant variation of extra-miniature bearings is available for use in the latest downsized and weight-saving products.

Feature:

1. Bearings with a bore size smaller than 2 mm are available in many versions based on 18 basic types of 3 metric series (68, 69, 60) and 6 basic types of the R series (inch). Available in high carbon chromium steel or stainless steel, plain or flanged, shielded or open types.

2. This particular line of miniature bearings enables manufacturers to further downsize their products without compromising requirements for speed, low starting and friction torque, reduced vibrations and noise.
