Features:
Double direction angular contact thrust ball bearing 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°. Consequently, the influence of centrifugal force is less and they can withstand higher speed and have higher rigidity.
Double direction angular contact ball bearings in series 20 and 29 have the same inner and outer diameters as the double-row cylindrical roller bearings in series NN30 and NN49 respectively, and they are both used for high axial loads.
Their cages are machined brass.
There are the BTR,BAR 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.
