Product detailed description
The double-acting K17X piston seal has an innovative design and consists of a PTFE sealing ring and an elastomer ring. The special design of the PTFE ring increases extrusion resistance while minimising the risk of blow-by. K17X provides low friction and minimal breakaway forces in demanding hydraulic applications.
Advantages
- No blow-by effect
- Low friction and no stick-slip
- Excellent dynamic and static sealing
- Long service life
- High extrusion resistance
- High speeds and frequencies
- Designed for grooves according to ISO 7425/1
Applications
- Cranes
- Injection moulding machines
- Hydraulic press cylinders
- Forklift trucks
- Construction machinery
- Servo cylinders
- Hydraulic hammers
- Wind turbines
- Automotive industry
Also searched as: piston seal, piston U-cup, hydraulic seal, hydraulic cylinder seal, NBR, nitrile, PTFE, teflon, bronze, Kastas, K17X, Kastas K17X.
