ANGULAR CONTACT BEARINGS

Angular contact bearings are ideal for use in gearboxes, pumps, electric motors, and clutches or other high-speed applications.

They are commonly used in the Materials Handling, Machine Tool, Steel Mill, and Wind Energy industries.

Although angular contact bearings can accept thrust loads in only one direction, they can be manufactured at different contact angles (usually between 0 and 45 degrees) to transfer the load acting upon the bearing.

Angular contact ball bearings are under high one-way axial load, the larger the contact Angle, the greater the load capacity.Cage material with steel, brass or engineering plastic, stamping or cutting molding way, depending on the bearing form or use different selection.There are other combination angular contact ball bearing, double row angular contact ball bearing and four-point contact ball bearing.
Angular contact ball bearings can bear radial load and axial load at the same time.Can work under high speed.The larger the contact Angle, the higher the axial bearing capacity.High precision and high speed bearing contact Angle usually take 15 degrees.Under the effect of axial force, the contact Angle increases.Single row angular contact ball bearings can only carry axial load in one direction, when bear radial load, will cause the additional axial force.And only limit shaft or shell axial displacement in one direction.If double installed in pairs, make a pair of bearing outer ring relative, namely the wide end facing the wide end face, the narrow end face the narrow end.This can avoid the additional axial force, but also can be in two directions the shaft or shell limits in the range of the axial clearance.

Angular contact ball bearing because of its outer ring raceway can have relative displacement in the horizontal axis, so can bear radial load and axial load at the same time, joint load (single row angular contact ball bearings can only carry axial load of single direction, therefore is generally installed in pairs) is often used to.Retainers made of brass, synthetic resins, according to the bearing form, the conditions of use and distinguish.

The type 7000 c (∝ = 15 °), type 7000 ac (∝ = 25 °) and 7000 b (∝ = 40 °) this kind of lock on the outer ring of bearing, generally inside and outside the circle cannot be separated, can bear radial and axial load and axial load in one direction.Carry axial load capacity is determined by contact Angle, contact Angle is big, has the ability to carry axial load.This kind of bearing can limit shaft or shell axial displacement in one direction.
