angular contact ball bearings Machine tool screw bearing 20TAC47BSUC10PN7B

Angular Contact Ball Bearing is mainly applied on high speed, high precision and little axial load occasions, such as airplane engine main shaft, machine tool main shaft and main shafts of other high speed precision machine. It can also be applied on high frequency motor, steam turbine, oil pump, air compressor and printing machine etc. It is one of the bearings most widely used in machinery industry.

    NSK 20TAC47BSUC10PN7B angular contact ball bearings can only bear the axial load of a single bearing. They generate additional axial forces when subjected to radial loads, so they are always used in pairs. Double row angular contact ball bearings can withstand radial and axial loads and have radial loads. Require:

    NSK 20TAC47BSUC10PN7 bearing angular contact ball bearings are mainly used in food machinery, electrical equipment, painting equipment, high-frequency motors, centrifugal separators, machine tool spindles, etc. Double row angular contact ball bearings are mainly used in oil pumps, printing machines, food packaging machines, electric Welding machine, fine chemical machine, etc.

    1. The frictional resistance is small, the power consumption is small, the mechanical efficiency is high, and it is easy to start.

    2, the size is standardized, interchangeable, easy to install and disassemble, easy to maintain.

    3. Compact structure, light weight and smaller axial size.

    4. High precision, high speed, low wear and long service life.

    5, can bear radial and thrust combined load at the same time;

    6, in a large load-speed range, unique design can obtain excellent performance;

    7. Bearing performance is relatively insensitive to fluctuations in load, speed and operating speed.
