Angular contact ball bearing
Single row angular contact ball bearing can only bear axial load in one direction. This type of bearing is usually adjusted relative to the second bearing. Their bearing rings have upper and lower shoulders and are inseparable.
Four point contact ball bearing is a radial single row angular contact ball bearing. Its raceway is used to support the axial load acting on two directions. For a given axial load, a finite radial load can also be supported. The bearing is of separate design, that is, the outer ring with ball and cage assembly can be installed separately with two inner ring half rings.
The double half inner rings of four point contact ball bearings have shoulder with grooves. When used in combination with cylindrical roller bearings, the oil flow is improved. In addition, the concave part can also be used for disassembly.
