    The limit speed of angular contact ball bearing is high, it can bear both radial and axial load,also can bear the pure axial load,its capacity of axial load is depended on its contact angle,and will increase with the contact angle's increase.such bearings have following three structures:
    Single-row angular contact ball bearings, including separation type and non-separation type two forms. S70000 type is the basic of separation-type ,SN70000 type is a inner ring separation type. Its inner ring and outer ring can be installed separately,suitable for installation condition which is restricted . Its contact angular is 15.non-separation angular contact ball bearings the innner ring and outer ring can not be installed separately.the following is three structures:
    Contact angle a=15o,latch at the outer ring is 70000C type
    Contact angle a=25o, latch  at the outer ring is 70000AC type
    Contact angle a=40o, latch  at the outer ring is  70000B type

    Double-row angular contact ball bearings are non-separation bearings ,they can bear greater radial and axial bi-direction load and torque load,but mainly radial load,it can limit axial or shell do two-way axial displacement,compare to the single-row angular contact ball bearings,they have better rigidity,the contact angle is 30.
    Four-point angular contact ball bearings are separate bearings, QJ0000 type with two-semi-innner rings, QJF0000 type with two-semi-outer rings,the contact angular is 35. at no load and pure radial load,steel ball and rings will  be  four-point contact,while, under pure radial load,steel ball and rings will  be  two-point contact and can bear bi-direction axial load. such bearings also can bear torque load and have the function of both single-row and double-row angular contact ball bearings. Only when have two-point contact, this bearing can be guaranted in normal work
    Angular contact ball bearings in our company mainly use the machined solid cage,four-point contact ball bearings use the brass or aluminum machined solid  cage.
