Characteristics of thrust ball bearings
- Aug 01, 2017 -

1. One-way, two-way type

2, thrust ball bearings can only withstand axial load, one-way thrust bearings can only withstand a direction of the axial load, two-way thrust bearing can withstand two direction of alternating axial load.

3, thrust ball bearing can not limit the radial movement of the shaft or box, its limit speed is low, one-way thrust bearing can limit the axial movement of the shaft or box side, two-way bearings can limit the shaft or box in two direction of the axial movement.

4, when using this kind of bearing, if the Axis and box hole of the axis of different heart, will cause premature bearing damage, in order to eliminate this undesirable phenomenon, can be in the living ring between the outer diameter and the box hole to leave 0.5~l mm radial clearance. At the same time, the Axis center line and the box support surface should be kept vertical, in order to eliminate because the box support surface and Axis center line is not perpendicular to the bearing center tilt, can be in the living Circle support surface cushion with elastic linings, such as paint cloth, leather and oil-resistant rubber pads.

5, thrust ball bearings in operation, due to the role of inertia force, the steel ball and the raceway also to produce sliding between, and make the temperature increase, the work surface easily damaged. Therefore, in order to prevent the steel ball from sliding between the raceway, the thrust ball bearing must be minimized axial force in the work.

6. In order to allow installation error, whether it is one-way or two-way, you can choose spherical spherical seat cushion or with spherical seat ring type.
