The plane bearing is installed on the top of the shock absorber, between the spring and the top rubber of the shock absorber, and it can rotate freely under the pressure of up and down.

The role of the plane bearing:

1. The function of shock absorption and the active link of the car body

2. Ensure the flexibility of steering

When the vehicle turns and the wheels rotate, it is ensured that the suspension can rotate with the wheels.

Automobile shock absorber plane bearing structure

1. The automobile plane bearing is composed of rolling elements, shaft washer (tightly fit with the shaft) and seat washer (there is a gap with the shaft and tightly fit with the bearing seat hole).

Ball type:

Plastic slip ring type:

Lubricating parts of automobile plane bearings: between the plane bearing cavities.

Working conditions of automobile plane bearing: the working environment of the plane bearing is harsh (sand, muddy water erosion), and the working strength is high; the plane bearing only bears the axial load and does not bear the radial load; because the axial load is evenly distributed on the rolling elements Therefore, the bearing capacity of the plane bearing is large.

Combined with the working conditions and structural characteristics of the plane bearing of the automobile shock absorber, the grease must have the following characteristics:

※ Broad high and low temperature performance;

※ Very small friction coefficient, excellent extreme pressure resistance;

※ Very low evaporation loss and stencil oil separation;

※ Good lubricity, small working torque and good adhesion;

※ Excellent water and corrosion resistance, oxidation resistance and long service life;

※ It has good compatibility with most kinds of plastics and rubbers.

The company's lubrication solutions for plane bearings:

A plastic plane bearing lubrication scheme

Select lubricating grease made from PTFE thickened high viscosity synthetic oil, adding solid anti-wear material and structure improving agent. It is characterized by good high and low temperature resistance, excellent waterproof and sealing performance. It has good compatibility with plastic materials.

B Metal Ball Bearing Lubrication Scheme

It is a lubricating grease refined by using polyurea-based thickened and refined synthetic oil, and adding special anti-wear materials and structure improvers. It is characterized by excellent wear resistance, extreme pressure and water resistance. It can meet the long-life lubrication of bearings.

Bench application test:

After the test, the grease adhered well in the plane bearing and the lubrication was full. Torque values meet customer requirements.
