3. Application and Properties  

It seals the rod, shaft, pinm and rotary joints which make rotating or swinging motion. Rotary hydraulic transmission exists in industries such as engineering machinery, construction machinery and car devices. Can be applied in occasions where piston rod or piston sealing are required. Low friction, no crawling and no stick-slip behavior, simple groove, exellent wear resistance performance and dimension stability.
