Description
This Square Compact Rod Seal GSR is composed of a rubber O-ring and a PTFE ring. The material is PTFE+NBR. In special cases, the rubber will be used FKM. The rod seal ensures that when the rod circulates back and forth in the gland, the pressurized fluid will not leak out of the system. It can be applied in special cylinders, pumps, and valves, machine tools, robotics, servo equipment, etc.
The Square Compact Rod Seal GSR is a very effective and reliable low friction seal. For reciprocating hydraulic systems. It is applicable to high and low-speed reciprocating motion environments, a wide range of fluids, and high-temperature conditions. Suitable for a larger gap of the piston rod. The low friction and simple groove allow this Square Compact Rod Seal GSR to work in the medium with oil spots.
