Product Description

Product Description

Description

MG Ring is a very effective and reliable low friction seal. It is particularly suitable as a rod seal in both high and low pressure systems.The double-acting  Ring is a combination of a based slipper seal and an energizing O-Ring. It has an interference fit which together with the squeeze of the O-Ring ensures a good sealing effect even at low pressure. At higher system pressures, the O-Ring is energized by the fluid, pushing the MG Ring against the sealing face with increased force. The geometry of the Ring ensures good static sealing and allows the lubricating hydrodynamic fluid film to be built under 
the seal in linear applications.

Pressure:	Up to 60 MPa
Speed:	Up to 15 m/s
Material:	PTFE(PU)+NBR\FKM
Temperature:	-45 °C to +200 °C
