Single row angular contact ball bearings

Angular contact ball bearing high speed limit, both radial and axial loads, there may be subject to pure axial load, the axial load capacity has its contact angle determines the contact angle greater the axial load capacity of more large, usually no more than 40 °, belongs to the heart thrust angular contact ball bearings. These bearings are widely used in the mill roll axial positioning.
