Mining Seal XSP55
Function:
Compact piston seal set, designed to seal the hydraulic fluid between two pressurized spaces, preventing the flow of the fluid to the other side and transforming the pressure force into the movement.
Features:- Double acting piston seal, designed with interference on the ID which provides a good static fit in the groove.
- Consisting of a PU or elastomere sealing element and all-over fitting backup rings with bracket guide rings sitting on.
- Useable for short and long stroke lengths.
Good dynamic and static sealing performance.- High frictional force.
