Double-direction angular contact thrust ball bearings
LYNBC Double-direction angular contact thrust ball bearings are specially designed high precision bearings for the mail spindles of machines tools.
Compared with the thrust ball bearings , this type contains more balls of smaller diameter and has a contact angle of 60°. Consequently, the influence of centrifugal force is less and they can withstand higher speed and have higher rigidity. They are both used for high axial loads. Their cages are machined brass. There are the series of highly rigid angular contact ball bearings suitable for high speed that can be easily replaced by these double-direction angular contact ball bearings. They are usually used in combinations of more than two bearings and with a preload. Their contact angle is 60° .For more details , please contact LYNBC technical department.
▲ LYNBC can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNBC Technical Center if you need any assistance in this area.
