Detailed Description
Thrust ball bearings from a Ball (with Cage), an axis circle (axis bear with) and one seat (with the shaft with a space-tight housings with) components, ball and ring in the shaft seat Between the rotation. Only under the direction of the axial load, can not afford radial load. As axial load is evenly distributed on each ball, the greater load capacity, but working hours, greater temperature rise, allowing a lower speed limit.
Thrust ball bearings can not restrict or shell axis of radial movement, but limits the shaft and shell axial movement in one direction, therefore, such bearings are usually associated with the use of deep groove ball bearings.
Installation, shaft and shell holes of the axis must be of one mind, otherwise, they will focus on stress caused due to premature bearing damage. In order to eliminate this negative phenomenon, here circle diameter hole between the left and Shell 0.5 ~ 1 mm of radial clearance. Shell supporting shaft centerline and should ensure that the vertical surface, not tilted axis and the deflection occurred, or will be caused due to uneven distribution of load bearing premature damage. To remove the bearing axis tilt, can be present circle on the surface of the pad to support flexible materials such as oil rubber, leather, or a dribbling Block of the thrust ball bearings.
The general thrust ball bearings plate stamping cage when ≥ 250 mm diameter, using entities Cage
Thrust ball bearings are separated-bearing, according to its structure is divided into one-way thrust-and two-way thrust ball bearings. One-way thrust ball bearings to bear in one direction axial loading, two-way thrust ball bearings can withstand the two directions of the axial load. They can not bear the radial load.
Thrust ball bearings is also available with cushions of the structure, due to the installation of cushions面呈spherical shape, it is aligning bearing performance, can reduce the impact of the installation error.
Thrust ball bearings are mainly used in automobile, machine tools and other industries.
