   Bearing on the use of the machine is mainly used for the following three parts: spindle, ball screw shaft and the general.

  Machine tool spindle bearings as the basis for component parts, its performance directly affects the speed of the machine, rotary precision, rigidity, resistance to cutting chatter vibration, noise, temperature rise and thermal deformation, thereby affecting the machining accuracy of parts, surface quality. Therefore, the machine must be equipped with high-performance SKF Bearings.

   The accuracy of rolling bearings are generally divided into P0, P6, P5, P4 and P2 five levels for precision machine tool spindle bearings precision should be P5 and above level, and for CNC machine tools, machining centers, high-speed, high precision machine tools spindle bearing, you need to use P4 level and above, super-precision bearings.

   Machine tool spindle bearing usually include SKF deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, angular contact thrust ball bearings, tapered roller bearings and thrust bearings of six structure types.
