O-rings are typical extruded seals. The compression rate and extension of the cross-sectional diameter of the O-ring are the main content of the seal design, which is of great significance to the sealing performance and service life. The good sealing effect of O-rings largely depends on the correct matching of O-ring size and groove size to form a reasonable compression and extension of the sealing ring.

Several factors affecting the performance of seals
The movement speed is very low (≤0.03/s), the smoothness of the equipment operation and whether there is crawling should be considered. When the moving speed is very high (≥0.8m/s), the ink used for the lubrication of the device may be destroyed, and the seals will be heated by friction due to the lack of good lubrication, which will greatly reduce the service life. It is recommended that rubber and plastics conform to the seal and work within the speed range of 0.3m/s~1.2m/s.
