Description
Piston seal composed of PTFE sealing ring energized by O-Ring. Function: Dynamic sealing of piston; low friction, no stick-slip. Materials: PTFE (virgin, bronze-filled, carbon-filled) + O-Ring (NBR, FKM, etc.). Temperature range PTFE: -100°C to +250°C. Chemical resistance: Virtually universal. Installation: Requires expansion and calibration; use assembly cone and calibration sleeve. Minimum mountable sizes (closed groove): KPOR30 >8 mm, KPOR31 >8 mm (series 000). Applications: High-speed, high-temperature hydraulics.
Possible Applications
This elastomer-energized piston seal is deployed primarily in high-performance hydraulic actuators and servo-cylinders operating within demanding industrial machinery. Typical implementations include injection molding machines, heavy-duty metalforming presses, and flight-control actuation test rigs where precise positioning and rapid directional changes are mandatory. Because the low-friction interface eliminates breakaway jerking, the component ensures ultra-smooth linear motion at both micro-step velocities and high actuation speeds. Furthermore, the broad thermal and chemical resilience profile makes it well-suited for hydraulic systems utilizing aggressive synthetic fire-resistant fluids in extreme ambient environments.
