Super Precision Ball Bearings

Super Precision bearings includes a full range of single row angular contact bearings and deep groove ball bearings that are designed to meet the following requirements:
Extreme accuracy
High rotational speed
Quiet and smooth running
Minimum friction and heat generation
Controlled rigidity
Three series of Super Precision angular contact bearings are available, ISO series 19, 10 and 02 with preferred contact angles of 15 and 25 degrees.
To provide for a wide variety of applications, a choice of standard preload loads are available. In addition, these bearings are universally faced so that pairs can be mounted back-to-back or face-to-face without affecting the preload value. The bearings are also matched on bores and outside diameters to improve load sharing.
