   ZYS precision angular contact ball bearing with 15 ° (C) and 25 ° (AC) contact angles. As for the angular contact ball bearings, the bigger the contact angle is, the greater the axial load capacity is, but the lower the limited speed of bearings becomes. Therefore ,the spindle, with high speed and small axial load ,should adopt the 15 ° angular contact ball bearings,whereas the 25 ° angular contact ball bearing should be adopted.
