The double acting BSF Glyd ring is a combination of a slipper seal and an energizing o ring. It is produced with 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 glyd ring against the sealing face with increased force.
BSF works perfectly as double acting piston seals of hydraulic components such as injection molding machine, machine tools, presses, excavators, forklifts & handling machinery, agriculture equipment, valves for hydraulic &pneumatic circuits and so on.
