1.Standard Materials

Seal ring: filled PTFE

O-Ring: NBR or FKM

2.Application Range

Rotary hydraulic transmission exists in industries such as engineering machinery, construction machinery and mobile devices. It seals the rod, shaft, pin, and rotary joints which make rotating or swinging motion. Double acting rotary seal, can undergo pressure from both sides or alternating pressure. Installed in grooves of ISO 7425 standard. Single acting structure of higher rotating speed.

Design and apply please refering to Trelleborg's TG4, Merkel's M16, Parker's OQ, AS’s YRB series standards.
