Four point contact bearing is a special type of rolling bearing, mainly used as a key component in the automotive industry, aerospace, machine tool manufacturing, heavy machinery and other fields. It can withstand large combined loads such as axial and radial loads, overturning moments, etc. When using four point contact bearings, the following points should be noted:

1. Choose a four point contact ball bearing with the same or higher quality for replacement, to avoid using temperatures outside the range and avoid corrosion.

2. Use professional tools for installation and disassembly, avoid using unauthorized tools, and avoid contamination with moisture, dust, and dirt.

3. During installation, it is necessary to apply equal pressure on the circumference of the ring end face, and adjust the clearance and apply lubricating grease.

4. Regularly monitor the bearings and seek professional assistance. Regular maintenance is crucial, including checking the pre tightening torque of the ring mounting bolts, which need to be checked again every 500 hours of operation.

5. When using, avoid exceeding the rated load of the four point contact bearing, otherwise it may cause bearing failure and damage.

When installing four point contact bearings, it is necessary to pay attention to the condition of the shaft or bearing seat to ensure the correct installation and lubrication of the bearings.

7. When using, it is necessary to pay attention to the temperature of the bearings to avoid excessive heating, otherwise it may lead to bearing failure and damage.

8. For the dismantled and cleaned turntable bearings, it is necessary to follow the assembly drawing and check the pre tightening torque of the ring installation bolts to ensure the safe use of the four point contact bearings.

The above are the precautions to be taken when using four point contact bearings to ensure the safe, stable, and reliable operation of the bearings.
