About Oil Seal Use Guides:
- Oil seals that are not used temporarily should be kept properly to prevent contamination with oil, dust or sun exposure.
- When the shaft diameter is worn into a "V"-shaped groove, so that the contact pressure between the new oil seal lip and the shaft cannot be reduced, the displacement method can be used to make up.
- When the lubriC.A.Ting oil volume of the reducer is less than or equal to 7 liters, the amount of lubricant added per liter is 20-30ml;
- When 7-15 liters, the amount added is 15-20ml per liter of lubriC.A.Ting oil;
- When>15 liters, add 10ml per liter of lubriC.A.Ting oil.

Basic Requirements For Sealing Materials:
- The performance of the sealing material is an important factor to ensure effective sealing. The selection of the sealing material is mainly based on the working environment of the sealing element, such as the temperature, the working pressure, the working medium used, and the movement mode. The basic requirements for sealing materials are as follows:
1. Have certain mechanical properties, such as tensile strength, elongation, etc.;
2. Appropriate elasticity and hardness, small compression set;
3. High temperature and low temperature resistance, no decomposition or softening at high temperature, and no hardening at low temperature;
4. It is compatible with the working medium, without swelling, decomposition, hardening, etc.;
5. Good oxygen resistance and aging resistance, durable;
6. Abrasion resistance, no corrosion to metal;
7. Easy to shape and process, low price.
