The excavator SPG seal consists of an anti-wear filled PTFE ring and a rectangular rubber seal. The rectangular ring provides a pre-tightening force that compensates for the wear of the PTFE square ring. Hydraulic system, reciprocating, two-way piston seal under high pressure and low pressure and high frequency conditions. This seal has a low frictional resistance and ensures high wear resistance. Since the single seal has a two-way sealing capability, the installation space is eliminated.
Low friction PTFE bronze with square ring is a low friction piston seal. PTFE + Bronze seal ring is energized by a rubber o-ring to provide a long lasting high speed.Low friction, non stick slip phenomenon.Good wear resistance.
Excavator double acting PTFE seal has bidirectional sealing capability, eliminates installation space, seals with very low friction, eliminates creeping and ensures high wear resistance.
