3. bearings


Single row angular contact ball bearings are self holding units with solid inner and outer rings, and ball and nylon, steel or brass cage assemblies. The inner ring and outer ring raceways are mutually offset in the axial direction of the bearing. There are open and sealed bearings. They have very little self-regulation.
Many sizes of angular contact ball bearings are designed by x-life. These bearings are shown in the dimensions table. X-life quality bearings have improved raceway shapes and optimized surfaces. This results in a significant increase in the fatigue limit load of the bearing. In the revised life calculation, the life value is increased by more than 50%. Therefore, in certain applications, smaller bearings can be used if necessary.
Double row angular contact ball bearings are composed of solid inner and outer rings, and balls and retainers made of polyamide, stamping steel sheet, or brass. They are similar in structure to a pair of o-shaped single-row angular contact ball bearings, but are more compact. They have different sizes of contact angles and design of bearing rings.
The bearings can be open and sealed. The open bearing outer ring has a cutting groove for sealing or dustproof cover due to the production technology used. Sealed bearings require no maintenance and are particularly suitable for economical bearing applications. The self-aligning range of angular contact ball bearings is very small.
