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.

For heavily loaded applications or where greater rigidity is required, it may be necessary to use a multiple set. The outer surfaces of matched multiple sets are marked with a “V” to ensure correct orientation and order.
