Thin Section Ball Bearing
- Outer diameter: 63.5mm~317.5mm
- Bore diameter: 50.8mm~304.8mm
- Rated load: 1650N~41340N
Thin section ball bearings are often referred as constant section bearings, and angular contact is one of the mostly used configurations (also including deep grove radial contact and four-point contact). Angular contact ball bearing features a circular pocket separator and its inner or outer ring is counter-bored to reduce one shoulder of the raceway to form the angular contact.
Its assembly method permits the use of a greater complement of balls and maintains a larger contact angle, making this type bearing can sustain greater axial loads. It can sustain axial load and unidirectional thrust capability, so this bearing should be used together with another bearing.
The chief advantage of angular contact ball bearing is that it offers greater axial load resisting capacity than a deep groove radial ball bearing or four-point contact radial bearing.
The difference between deep groove ball bearing is that angular contact ball bearing has sufficient diametral clearance to produce a substantial contact angle for resisting axial load. The standard thin wall angular contact ball bearing features a constant angle of 30°and approximately 65% of a full complement of balls.
