* Other material combinations can be customized
according to working conditions.
The GRS is a rotating combination seal consisting of a dynamic PTFE seal and a standard size O-ring with a static side reinforcement,suitable for hydraulic and rotary joints.
Low dynamic and static friction
High temperature & speed allowed
High extrusion resistance
Simple groove,space saving design
High compatibility, almost compatible with all fluids
Rotary hydraulic rotation exists in various industrial fields such as construction machinery, construction machinery and automobile equipment. The GRS seals are used to seal rods, shafts, pins, swivels, etc. that have a rotating or oscillating motion. It is a double rotating seal that can withstand pressure on both sides or alternating pressure. Installed in the groove of the ISO7425 standard. There is also a single-acting structure with a higher rotational speed.
Petroleum-based hydraulic oil, flame retardant hydraulic fluid, environmentally safe hydraulic fluid (bio-oil), water and others.
