Home - Practical Machinist - class 7 spindle bearings

3/1/2010· class 7 spindle bearings. I am currently in the process of replacing the spindle bearings in my Trak DPM mill and was curious to know how much difference there is in the different bearing classes. It has class 5 bearings in it now but most of the new machines have class 7, including the new proto traks if I''m not mistaken.

Precision Bearings | Bearing Service

Generally a bearing is considered high precision when it is manufactured to ABEC 5, 7 or 9 (ISO 5, 4, 2) tolerances, with ABEC 7 (ISO 4) being the most popular. Higher precision bearings are available in ball bearings, angular contact ball bearing, ball screw support bearings, cylindrical roller bearings, spherical roller bearings and tapered roller bearings.
