Introduction to angular contact ball bearings:
Angular contact ball bearings have a high limit speed, can withstand radial and axial loads, and can withstand pure axial loads. Their axial load capacity depends on their contact angle and increases with increasing contact angle. This type of bearing has the following three structural forms:
Single row angular contact ball bearings are available in separate and non-separable versions. The S70000 type is a separate basic type, and the SN70000 type is an inner ring separation type. Its inner and outer rings can be installed separately, suitable for the parts with limited installation conditions. Its contact angle is 15. The inner and outer rings of the inseparable angular contact ball bearings cannot be installed separately. The bearing is the following three basic structures: contact angle a=15°, lock on the outer ring 70000C type contact angle a=25°, lock on the outer ring 70000AC type contact angle a=40°, lock on the outer ring 70000B.
The ball bearing is a non-separable bearing that can withstand large radial and axial bidirectional combined loads and moment loads. It can limit the axial displacement of the shaft or the casing. It has better rigidity and contact angle than the single row angular contact ball bearing. Is 30.
QJ0000 type double half, QJF0000 double half outer ring, four point contact ball bearing is a separate type bearing, the contact angle is 35. In no-load and pure radial loads, the steel ball and the ferrule are four-point contact. In pure axial load, the steel ball and the ferrule will have two points of contact and can withstand two-way axial load. This bearing can also withstand moment loads and has the function of single row and double row angular contact ball bearings. The bearing is guaranteed to work properly only when there are two points of contact.
Angular contact ball bearings are mainly made of solid cages, and four-point contact ball bearings are made of brass or aluminum solid cages.
