Bearing Precision Ratings

Precision bearings are bearings with a manufacturing tolerance rating of ABEC 1 or higher: a higher ABEC number means a higher level of precision. For most applications, ABEC 1 or ABEC 3 bearings will offer significant accuracy. When highly precise position is required, ABEC 5 or ABEC 7 bearings should be specified.

Precision Bearing Materials & Uses

Precision bearings from WM Berg are made using hardened steels as opposed to standard bearings which are typically made with low-carbon steel. Precision bearings are used in a wide range of applications in healthcare, aerospace, motion control and many other industries where greater accuracy, increased load capacity and superior system performance are required.
