Angular contact turbo ball bearing 5305 -zz

There are raceways on the inner and outer rings of angular contact ball bearings, and the inner and outer rings can make relative displacement along the axial direction of the bearing. This kind of bearing is especially suitable for bearing compound load, that is, radial and axial load acting at the same time. The axial load bearing capacity of angular contact ball bearing varies with the contact angle α Increases with the increase of. The contact angle is the angle between the connecting line of the contact point between the ball and the raceway in the radial plane and the vertical line of the bearing axis.

There is an angle between the ligature of steel ball of Contact ball bearing and its contact point with inner & outside circles and radical side. The angel is generally 15°,30°,40°, 25°showing with letter/letters C, A, B,AC respectively.
Angular contact ball bearings mainly take large axial load, the greater the contact angle, the greater the load capacity to withstand.
Cage materials are steel, brass or engineering plastics, and molding methods are stamping or turning, which is depending on the form or different applying conditions of the bearing.
