Angular Contact Ball Bearings can bear both radial load and axial load, can work at high speed. The greater the contact angle, the higher the axial load capacity.High precision and high speed bearings normally use 15° contact angle , under the action of axial force, the contact angle will increase.Single Row Angular Contact Ball Bearings can only withstand axial load in one direction .When a radial load is applied, an additional axial force is induced.and can only limit the axial or housing to do displacement of the shaft in one direction.Two row Angular Contact Ball Bearings can withstand a larger radial load-based radial and axial combined load and torque load , limit the axial displacement of the shaft in both directions.It has limited inclinability of Inside the bearing, between the outer rings of Two row angular conatact ball bearings in component that limits biaxial displacement of the shaft and housing.
Grinding machine spindle bearing : adopt 15°and 25° contact angle design,provide a certain axial support, match work method, meet the rigidoutput of various load requirement ,High Precision Technology, ensure the stable precision performance under high speed .Application area: lathe, grinding machine,working spindle of machining center and so on .
Four-point contact ball bearings are separable bearings,there are generally two structures. QJ0000 type -- Double half inner ring, one integral outer ring;QJF0000 type -- Double half outer ring, one integral inner ring . Contact angle mostly adopt 35°.Under pure radial load,the ball contacts the raceway at four points.Under uniaxial load,The ball contacts the raceway at two points.it can bear axial load in two directions,It can also bear certain eccentric load, i. e. Moment Load.
Character of Walking reducer of angular contact bearing is overload design can meet strong load requirements,aim at special design for torque , ensure constant and stable torque output .Application : used in low speed and heavy load field such as track transmission.
