Product description
| 1.Features |
| The piston rod has a one-way actuation seal ring consisting of an anti-wear filled PTFE ring and an O-ring rubber seal ring. The O-ring provides elasticity, compensates for the wear on the PTFE step rings, and has a one-way sealing effect. Suitable for sealing the piston rod of a hydraulic cylinder. A guide ring is generally used. If the axle diameter is less than φ30, the split groove shall be adopted. |
| 2.Materials |
|
The wear ring is made of PTFE bronze composite; The O-ring is Nitrile Butadiene Rubber (NBR); or Fluororubber (FKM). |
| 3.Performance |
|
The step ring for the rod resistance GSJ is suitable for a single side-pressure piston rod; Very high pressure stability under pressure and harsh conditions ; or Fluororubber (FKM); Good thermal conductivity; Very good reliability against extrusion ; High wear resistance; Low friction, no stick-slip phenomenon. |
| 4.Operating Conditions |
|
Pressure: ≤40MPa; Speed: ≤5m/s; Frequency: ≤5Hz; Temperature: -30°C to +200°C (depends on the material of the O-ring); Medium: mineral-based hydraulic oil, flame retardant liquid (HFA, HFB), biodegradable hydraulic oil, water. |
