OKP
The piston seal set profile OKP is a double-acting seal element. It is especially designed for cylinders in the heavy hydraulics for working pressures up to 500 bar. It consists of a thermoplastic slide ring and a elastic pretension element.
ADVANTAGES ARE
- very good abrasion resistance
- small breakaway torques, even after longer stillstand
- impervious to pressure hammers
- very good security of extrusion even at high pressures and large gap
- best static and dynamic density
- small fitting area
- simple mounting on one-piece pistons because of divided slide ring
APPLICATION RANGE | |
working pressure: | ≤ 50 MPa (500 bar) |
working temperature: | - 30 °C to + 110 °C |
surface speed: | ≤ 1,0 m/s |
media: | Mineral oil-based hydraulic oils |
Chifly used for sealing of cylinders in the heavy hydraulics. The dimension series is largely orientated on the installation guidelines of ISO 7425-1.
MATERIAL | |
slide ring: | modificated thermoplastic (WK019) |
pretension element: | NBR-based elastomer |
MOUNTING INSTRUCTIONS
To ensure a faultless function, the fitting areas have to be burred and cleaned thorough. The cylinder lners have to show lead-in chamfers. The sealing OKP can be mounted into closed grooves.
For special cases of application (high temperatures, speed, specific pressure, use in water, HFA-, HFB-fluids etc.) please get in contact with our consultancy service.
