Name£ºAngular Contact Ball Bearing
Introduction£º
Angular Contact Ball Bearing
Details£º
Angular contact ball bearings are particularly suitable for carrying combined (axial and radial) load. Sometimes, they can also carry pure axial load and operate in higher speed. Under radial load, axial component force which must be counteracted will be generated. Therefore, the bearings are normally adjusted against a second bearing.

Single row angular contact ball bearings can carry axial load acting in one direction only. In many applications, angular contact ball bearings in pairs or multi-arrangement should be used. Axial load carrying capacity of angular contact ball bearings increases with increase of contact angle.

LEGEND standard single row angular contact ball bearings have separable and non-separable designs. Contact angle of separable bearings is 15¡ã, and contact angles of non-separable bearings are 15¡ã, 25¡ã or 40¡ã respectively. Separable angular contact ball bearings can be divided into removable inner ring and removable outer ring according to the internal structures. Angular contact ball bearings have a pressed outer ring and more balls filled, and they have higher load carrying capacity. Mounting and dismounting of the bearings are very easy.

Stiffness of double row angular contact ball bearings with non-separable structure is better than that of single row angular contact ball bearings. Double row angular contact ball bearings can carry axial load in both directions and a certain tilting moment at the same time. Double row angular contact ball bearing is similar to single row angular contact ball bearing arranged in pairs or back-to-back in their operational effect, but its width is narrower.

Angular contact ball bearings are mounted singly or in tandem steel cage and machined solid cage. Solid cage is made of brass, bronze, various light alloy or phenolic resin. When angular contact ball bearings are used as high speed spindle bearings, the cages are often made of phenolic resin. Cages made of various materials are indentified by suffix.

In many cases, angular contact ball bearings can be provided in pairs or multi¨Carrangement. According to the mounting requirements, tandem, face-to-face or back-to-back arrangements can be selected for bearings. They can be supplied in matched sets of three or four bearings depending on the applications.

Three or four-point contact ball bearings are single row angular contact ball bearings with tow-piece inner ring or outer ring. They are separable. The bearings mounted in pairs can carry axial load in both directions and limit axial displacements in both directions. They take smaller space than that of double row angular contact ball bearings.
