718 Series thin-walled angular contact ball bearing

Thin walled angular contact ball bearings are a widely used type of angular contact ball structure in thin walled bearings. Thin walled angular contact ball bearings have a circular window hole holder, which lowers the edge of the inner or outer race raceway on one side of the deep groove ball bearing to form angular contact ball bearings. Its assembly method can accommodate circular hole cages and larger and more balls, forming a larger contact angle and obtaining greater axial load capacity. It can withstand radial and unidirectional thrust loads and is usually used together with another bearing of the same structure. The advantage of angular contact ball bearings is that they can provide greater axial load capacity than radial deep groove ball or four point contact ball types.

The difference between thin-walled angular contact ball bearings and thin-walled deep groove ball bearings is that thin-walled angular contact ball bearings have sufficient radial clearance to form sufficient contact angles to withstand axial loads.

Characteristics of thin-walled angular contact ball bearings:

The ratio of outer diameter to inner diameter is small, and the diameter of the rolling element is small, resulting in a large number.

Thin walled angular contact ball bearings have high axial bearing capacity. It has the advantages of high speed, high accuracy, and low noise and vibration, and is mainly used in situations where the axial force is high and deep groove ball bearings are not suitable.

The significant feature of angular contact ball bearings is their assembly method. A certain bearing ring, usually the outer ring of the bearing, has a sloping edge on one side. By utilizing the temperature difference between the inner and outer rings, the outer ring can be assembled together with the inner ring, steel ball, and cage to form an inseparable bearing. This bearing can withstand both unidirectional axial load and large radial load. When bearing axial loads, the inner and outer rings of the bearing can undergo certain preload adjustments.
