Angular contact ball bearing, 角接触球轴承) 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. Contact Angle to plane for diameter ball and raceway contact points connect with the bearing axis of the Angle between the vertical line. High precision and high speed bearing contact Angle usually take 15 degrees. Under the effect of axial force, the contact Angle increases. Angular contact ball bearing of both inner and outer ring raceway, and inner and outer phase of displacement of the bearing axis. This type of bearings is particularly suited to composite under load, namely the radial and axial role of negative charge at the same time. Angular contact ball bearing axial load capacity increases with the increase of contact Angle alpha. Contact Angle to plane for diameter ball and raceway contact points connect with the bearing axis of the Angle between the vertical line. Angular contact ball bearing model is divided into: alpha = 15 ° angular contact ball bearings ( The type 70000 c) ; Alpha = 25 ° angular contact ball bearings ( 70000 ac type) ; Alpha = 40 ° angular contact ball bearing, 70000 b) ; Back-to-back double angular contact ball bearing in pairs [ 70000C( AC、B) Type/DB] ; Duplex angular contact ball bearing in pairs (face to face 70000C( AC、B) Type/DF] ; Tandem double angular contact ball bearing in pairs [ 70000C ( AC、B) Type/DT] ; With ball gap of double row angular contact ball bearings ( The type 00000) ; No loading ball gap of double row angular contact ball bearings ( 00000 a) ; No ball gap, a double row angular contact ball bearing with dust cover ( 00000A- Z) ; No ball gap, two sides with a dust cover double row angular contact ball bearing, 00000A- 2 z) ; No ball gap, a double row angular contact ball bearings with seals ( Type 00000 ars) ; No ball gap, with seals on both sides of double row angular contact ball bearing, 00000A- Type 2 rs) ; Four point angular contact ball bearing, QJ0000 type) And 13 species.
