Manufacturer Rubber Ring For Top Cover Thickened Rubber Strip Air Filter Material
1. Prodcut introduction
The rubber sealing ring is an annular cover composed of one or several parts, which is fixed on one ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent leakage of lubricating oil and invasion of foreign objects.

3. Product advantages
1. The sealing ring shall have good sealing performance within the working pressure and certain temperature range, and can automatically improve the sealing performance with the increase of pressure.
2. The friction between the sealing ring device and the moving parts shall be small and the friction coefficient shall be stable.
3. The utility model relates to an axial-acting elastic rubber seal ring, which is used for a rotary shaft non-pressure seal. The sealing lip has better mobility and adaptability, can compensate for large tolerance and angle deviation, can prevent internal grease or oil leakage, can also prevent external splash water or dust invasion.
