Before taking the angular contact ball bearings course, it is recommended that you have passed the bearings basic course , or have some prior knowledge about bearings.This lessons may focus on features and benefits of single row and double row angular contact ball bearings. Arrangement of universally matchable angular contact ball bearings is also discussed. Four-point contact ball bearings are also considered. GQZ angular contact ball bearings are used in many pump and compressor applications. Three examples of demanding applications are presented. Following is something most characteristic about angular contact ball bearings,after reading it, you may get a new known to angular contact ball bearings. Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. If you have any other questions,you can call us.
