JIC-87715786 CASE SPGW Piston Seal
-
Type:
- SPGW typically refers to a double-acting piston seal with a symmetrical design that is suitable for bidirectional pressure.
- Often consists of a PTFE (Teflon) or polyurethane sealing ring combined with an elastomeric O-ring or energizer (e.g., NBR, FKM) for improved sealing performance.
-
Design & Function:
- Low friction due to PTFE or polyurethane material.
- High-pressure resistance (often rated for 300+ bar, depending on size).
- Wear-resistant, suitable for long service life in hydraulic cylinders.
- Self-lubricating (especially PTFE-based seals).
- Bidirectional sealing (works in both directions of piston movement).
-
Common Materials:
- Sealing ring: PTFE (Teflon), Polyurethane (PU), or other engineered plastics.
- Backup ring: Nylon
- O-ring: Nitrile (NBR), Fluorocarbon (FKM), or HNBR for high-temperature applications.
-
Typical Applications:
- Hydraulic cylinders (industrial, mobile, and heavy machinery).
- Construction equipment (excavators, loaders).
- Agricultural machinery (tractors, harvesters).
- Oil & gas, mining, and marine hydraulic systems.
-
Advantages:
- Reduced leakage compared to single-acting seals.
- Handles high pressure and dynamic movement efficiently.
- Suitable for a wide temperature range (depending on material).
