Choose CNC lathe spindle bearings, choose the right size but choose the wrong contact angle, your spindle will definitely fail soon!
Improper selection of contact angle will affect the speed, life and torque of the bearing, so it is very important to choose the right contact angle!
In addition to the conventional C-15° AC-25° B-40° TAC/760 series-60° angular contact ball bearings, we also have unconventional contact angles such as 18° and 21°.
CNC lathe spindle bearings generally use C and AC contact angles. From the perspective of the same model, the AC angle can withstand greater axial force than the C angle, and the C angle can reach a higher speed due to the relatively small axial force!
