1. Pay attention to take out the fixed amount of oil sealing before assembly

Check the oil seal of the skeleton, measure the size of the skeleton seal, and the size of the axis and inner cavity. Before installing the skeleton seal, clear the axis diameter and the inner diameter of the oil seal. The size of the inner cavity should be applied to the total diameter of the oil seal, and the damage of the skeleton seal should be checked. Deformation. The twisting spring is not falling off and corrosion. Avoid the skeleton sealing without flat skeleton during transportation. External force squeeze and impact, and destroy its true circle.

2. Pay attention to the processing and testing procedures of pre -installed equipment

The specifications of a large number of internal cavity and axis components are correct, especially the internal chamfering, without the slope. The shaft and the top of the cavity are processed and cleaned. Murder edges. Sand. Iron chips and other debris will cause irregular damage to the skeleton sealing. It is recommended to use chamfers in the chamfering area.

3. Pay attention to whether it feels smooth

Can I feel smooth when using it? Before installing the real circular skeleton seal, do not tear up the packaging paper prematurely to avoid the debris sticking to the surface of the oil seal and bringing it into a job. The characteristics of the skeleton sealing are that if it is not installed immediately, it is recommended to use a cloth cover on it to avoid foreign bodies connected to the oil seal. Hands or tools with lithium -based grease must be cleaned.
