Precision bearing

Angular Contact Ball Bearings (Angular Contact Ball Bearings) It can withstand both radial and axial loads. Can work at higher rotational speeds. The larger the contact Angle, the higher the axial carrying capacity. The contact Angle is the Angle between the contact point connection of the ball and raceway and the vertical line of the bearing axis in the radial plane. High precision and high speed bearings usually take a 15 degree contact Angle. Under axial force, the contact Angle will increase. Single row angular contact ball bearings: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft, booster pump, drilling platform, food machinery, dividing head, repair welding machine, low noise type cooling tower, electromechanical equipment, painting equipment, machine slot plate, arc welding machine Double row angular contact ball bearings: oil pump, Roots blower, air compressor, various transmission, fuel injection pump, printing machinery, planetary reducer, extraction equipment, cycloidal reducer, food packaging machinery, electric welding machine, electric soldering iron, square box, gravity spray gun, wire stripping machine, half shaft, inspection and analysis equipment, fine chemical machinery

Angular contact ball precision bearings Precision machine tool bearingAngular contact ball bearings can bear radial and axial loads at the same time, and can also bear pure axial loads. Their axial load capacity is determined by the contact Angle and increases with the increase of the contact Angle. Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, additional axial force will be caused, and corresponding reverse load must be applied. Therefore, this kind of bearings are generally used in pairs. Double row angular contact ball bearings can bear large radial and axial bidirectional combined loads and torque loads mainly radial loads. It can limit the two-way axial displacement of shaft or housing, and the contact Angle is 30 degrees. Angular contact ball bearings installed in pairs can bear radial and axial combined loads mainly in radial direction, and can also bear pure radial loads. The series configuration can only withstand axial loads in a single direction, while the other two configurations can withstand axial loads in either direction. This type of bearing is usually selected and combined by the manufacturer and submitted to the user in pairs. After installation, the preload interference is preloaded, and the ferrule and steel ball are in the axial preload state, thus improving the stiffness and rotation accuracy of the whole set of bearings as a single support.

Outer spherical precision bearing Its outer ring outer diameter surface is spherical Mainly used for bearing radial load mainly radialThe outer spherical bearings are preferentially used in situations requiring simple equipment and parts, such as agricultural machinery, transportation system or construction machinery. Mainly used to bear radial load mainly radial and axial combined load, generally not alone to bear axial load, this kind of bearing can be installed respectively inner ring (with a full set of rollers and retainer) and outer ring. The bearing does not allow the shaft to be tilted relative to the housing, and additional axial force will be generated under radial load. The size of axial clearance of this kind of bearing has a great relation to the normal operation of the bearing. When the axial clearance is too small, the temperature rise is higher. When the axial clearance is large, the bearing is easy to be damaged. Therefore, special attention should be paid to adjusting the axial clearance of bearings during installation and operation. If necessary, pre-interference installation can be used to increase the rigidity of bearings.
