Material:
Sealing body: filled with polytetrafluoroethylene (PTFE)
O-ring: Nitrile rubber NBR or Fluororubber FKM
The ST100 shaft uses a grid ring consisting of a low friction filled PTFE rectangular sealing ring and a rubber elastic body (O-ring) for sealing the piston rod in high-pressure system oil cylinders and servo oil cylinders for linear reciprocating motion, providing bidirectional sealing.
Technical data
Pressure ≤ 80MPaSpeed ≤ 15m/s
Temperature -54 ℃~+200 ℃ (depending on the O-ring composite)
Medium petroleum based hydraulic oil, flame retardant hydraulic oil, environmentally friendly and safe hydraulic fluid (bio oil), etc
Surface roughness Ra Rmax
Piston rod surface ≤ 0.2 μ m ≤ 3 μ mBottom of groove ≤ 1.6 μ m ≤ 6.3 μ m
Groove side ≤ 1.6 μ m ≤ 16 μ m
advantage:
- Excellent static sealing performance
- Allow for larger extrusion gaps- Low friction, no crawling phenomenon
Due to the availability of a wide range of materials, it has strong adaptability to working conditions
