Know the types and application of the rolling bearing

To know the types and application of the rolling bearing: 1. Centripetal thrust ball bearing thrust centripetal ball bearings can bear heavier bidirectional axial load and a small amount of radial load, axial rigidity, suitable for high speed, it is mainly used for lathe, boring machine, radial drilling machine and other machine tool spindle. 2. Thrust ball bearing thrust ball bearing contact Angle of 90 ', the structure is separable type, can only carry axial load. With a spherical seat thrust ball bearings are so can eliminate the influence of the installation error. Due to the centrifugal force of steel ball to race the lateral, easy to scratch, so not suitable for high-speed operation. This type of bearings is mainly used for machine tool spindle rotary worktable, vertical lathe, auto steering movement, etc. 3. Miniature ball bearing inside diameter less than 10 mm or less than 26 mm in diameter of bearing called miniature bearing. Miniature ball bearings are mainly used for various kinds of instruments and meters, micro motor, gyroscope, automatic control institutions and medical equipment, etc. 4. Linear motion ball bearings linear motion ball bearings by the outer ring and cage ( Also called ball loop frame) And 3 ~ 5 columns of steel ball. Friction coefficient than sliding bearing is much lower, a - A 0. 001-0. 003. This type of bearing radial clearance is small, high precision linear motion, it is mainly used for nc machine tools of the reciprocating mechanism, instrument automatic recording device, automatic tracking, and guide pillar of stamping die, etc. 5. Tapered roller bearings taper roller bearing roller and raceway for line contact line contact or modification, can withstand the heavier radial and axial load, also can be subject to pure axial load, front and rear wheels is mainly used in cars, machine tools, rolling stock, rolling mill, construction machinery, lifting machinery, printing machinery and all kinds of speed reducer, etc. Double row circular cone roller bearings is mainly used for machine tool spindle and the rolling stock and so on, four row circular cone roller bearings used in roll support, etc.
