NSK 7220AC Angular Contact Ball Bearing Industrial Reducer

Angular contact ball bearings can bear radial load and axial load at the same time.Able to work at high speed.The higher the contact Angle, the higher the axial bearing capacity.The contact Angle is the Angle between the contact line of the ball and raceway in the radial plane and the vertical line of the bearing axis.High precision and high speed bearings are usually 15 degrees of contact.The contact Angle will increase under axial force.

Product Description

Cage material:

Steel plate, brass or engineering plastic, molding methods are stamping or turning, depending on the bearing form or use conditions.

Single row angular contact ball bearings can only bear axial load in one direction, when bearing radial load, will cause additional axial force. And can only limit the axial displacement of the shaft or shell in one direction.

The angular contact ball bearings can undertake both the radial load and axial load in the mean-time. Such bearings can work at a high rotational speed. The bigger the touching angle is, the greater the bearing's load capacity is.
