Detailed description
7020 CD/P4A, 7020 ACDGA/P4A angular contact ball bearing installation form:
(1)Back to back installation
Bearing contact Angle line along the rotary axis direction diffusion, can increase the radial and axial bearing Angle rigid, resistance to deformation ability maximum
(2)Face to face installation
Bearing contact Angle line toward the rotary axis direction convergence, the bearing Angle rigid smaller.
(3) Series installation:
Bearing contact Angle line synthetic and parallel, can make the two bearing share the same direction work load
