Double Row Angular Contact Ball Bearing - Reinforced Nylon 66 Retainer, 32-degree Contact Angle | High Radial And Axial Load Support, Dual Sealing Options, Temperature Range -30 To 110 Degrees

These Double row Angular Contact Ball Bearing features can support both radial and axial load of joint load, limit the axial displacement of the shaft in two aspects. And two-way thrust ball bearings, the bearing limit rotational speed is higher, the contact angle of 32 degrees, good rigidity, can withstand overturning torque is large, widely used in car front wheel hub ( some models also used the same size for the double row tapered roller bearings).
Double row angular contact ball bearing has four kinds of structure deformation:
Type A: outside diameter less than or equal to90mm bearing standard design. No ball filling gap, thus can withstand equal to the two-way axial load. Using light glass fiber reinforced nylon 66retainer, bearing temperature rise is small.
Type A: outside diameter greater than 90mm bearing standard design. Side of ball filling gap, equipped with Z stamping steel cage or solid brass cage. Type E : a reinforced structure, the side with ball gap, can hold more of the ball, so the carrying capacity is higher.
Double shielded type and with two sealing ring type, A type design and E design of double row angular contact ball bearings can both sides with dustproof cover ( non-contact) or the sealing ring ( contact ). Sealed bearing interior is filled with antirust lithium base grease, operation temperature from - 30 degrees to 110 degrees. During use without lubrication, no heating installation.
