3. Application and Properties  

 

Can work under conditions of high speed, high pressure and that needs to keep pressure. For double acting  pistons such as piston accumulators, positional cylinders and bearing cylinders. High static and dynamic sealing effect, allow large extrusion space, can keep pressure, less leakage in the hydraulic cylinder, simple groove design, small installation space, excellent sliding performance, no stick-slip behavior.
