HIGH PRECISION BEARINGS  

High precision bearings are sometimes called super precision bearings.  They ar e specifically designed for rigid, high speed, and high precision machine tools spindles, where high speed and high accuracy are critically necessity.

 

  High Precision Angular Contact Ball Bearings  

Precision angular contact ball bearings are specially  designed for high precision machines.  They are available in large numbers of sizes of bores, which are almost virtually made available to every machine tools application where the bearings can be used.  It has similar characteristics like a conventional angular contact ball bearings, the inner rings and outer rings ar e offset in certain angle to the bearing axis, where the loads will be transmitted across this angle through the balls.  The design provides a capability to carry axial loads in one direction, in addition to radial loads.  An axial force acting in one direction will be produced under a radial load, and that axial force need to be counteracted, thus angular contact ball bearings are often used in a pair or set.  

 

  High Precision Cylindrical Roller Bearings  

  High precision cylindrical roller bearings have similar characteristics and features of its?ˉ conventional type.  Their cross section is relatively low, high radial load carrying capacity, as well as high speed applications.  They are designed specifically to provide high degree of stiffness, and carry heavy radial loads in high speed spindle applications, where running accuracy of spindle bearing is necessary.  High precision cylindrical roller bearings are also available as single row and double row types.
