Double-Direction Angular Contact Thrust Ball Bearings are specially designed high precision bearings for the main spindles of machine tools. Compared with the Thrust Ball Bearings in the 511 Series, this type contains more balls of smaller diameter and has a contact angle of 60°.They are designed to carry only thrust loads. High contact angles carry high axial loads.

The precision we offering are P5, P4, P2, SP and UP precision. If any requirement of the precison, please feel free to let us know.

All the bearings we are offering are direct factory price, fast delivery, perfect quality. For more bearings, please contact us by e-mail, wechat , whatsapp or skype.
