BSJ Hydraulic Seals – Rod compact seals

Description

Produced with a combination of special compound PTFE ring and 70 shore NBR O-ring,our BSJ design has a wide application area.Being able to be usded safely at high linear velocity,BSJ type seals can also work in higher temperatures or different liquids by means of changing O-ring used as pressure ring.By the help of its profile design they can be used as header pressure ring in hydraulic systems without having the problem of hydro-dynamic pressure.Apply to the working condition of fast speed, high pressure, and the necessary pressure keeping. Recommended for double-acting pistons as piston-type energy storage, supporting cylinder and positional cylinder. Double safety with low friction and high elasticity, good dynamic and static sealing performance, larger extrusion clearances can be allowed, at the same time with the function of holding pressure, less leakage in the hydraulic cylinder. Simple groove, small installation space, excellent sliding performance, no crawling phenomenon.No stick-slip effect when starting for smooth operation.
