Bearing Solutions for the Medical Industry

Miniature ball bearings have become essential components in the rotating elements of various equipments and machines. In response to the trend toward equipment and machinery that gets smaller, more compact, thinner and quieter, we manufacture hundreds of kinds of miniature ball bearings, including specialized types, from extremely small bearings with a 1.0 mm bore diameter and a 3.0 mm outer diameter to bearings that are about 20 mm in outer diameter.

The bearings consist of inner ring, outer ring, balls, retainer and cage. This type is the most generally used radial ball bearings for many applications.   Extra-thin-section deep groove ball bearings have a small radial cross-sectional thickness. They are used when extreme compactness is important. 

Deep groove ball bearings with extended inner rings are inch series bearings with their inner rings extended equally on both sides beyond the width of the outer ring. This feature simplifies the design and fabrication of parts closely surrounding the bearing.  

Thrust ball bearing consists of flat washers (without raceway groove) and ball-installed cage. This type can support an axial load only from one direction.   This type has a raceway groove on both washers and holds a higher load rating.  

The pivot ball bearing consists of outer ring and several balls. This type supports a tapered tip (pivot of normally 60°) of spinning shaft. 

 Deep groove ball bearings with flanged outer rings is a type that the flange extends around the entire circumference of the outer ring. This feature simplifies a process of the mounting of the bearing into housing.
