Clip Fabric Seal

The purpose of using fabric sandwiched rubber Sealing material is to increase the stiffness and strength of the Sealing ring, prevent rubber extrusion, and make it suitable for high pressure. At the same time, in the process of wear, rubber wears ahead of fabric. When the rubber of the parts with high contact pressure wears off, the wear extends to the parts with low contact pressure, so that the wear of the whole sealing surface tends to be uniform, but the friction does not change significantly. However, the lip of the rubber sealing ring sandwiched with fabric can easily scrape off the oil film on the sliding surface, so the lubricity is worse than that of leather and polytetrafluoroethylene.
