PS-65
Description
The PS-65 is a two piece single acting piston seal which consists of asymmetrical profile with pressure relieving grooves and a thermoplastic back-up ring.
Material: PU with a POM back-up ring
Product advantages
- superior static and dynamic sealing effect
- improved sealing gap thanks to the active back-up ring
- relief grooves against dynamic pressure
- easy assembly into the closed groove
- simple groove design
- high wear resistant
Applications
Heavy duty cylinders, crap cutters and hydraulic jacks
Operating conditiones
| Media | Mineral oils (DIN 51524) | HFA and HFB | HFC |
| Temperature (min.) °C | -30 | +5 | -30 |
| Temperature (max.) °C | +100 | +50 | +40 |
| Pressure Bar | ≤400 | ≤400 | ≤400 |
| Speed m/sec | ≤0,5 | ≤0,5 | ≤0,5 |
Surface roughness
| Surface roughness | Ra | Rmax |
| Sliding Surface ØD-Ød | ≤0.4 μm | ≤3.2 μm |
| Groove Base ØDb-Ødp | ≤1.6 μm | ≤10 μm |
| Groove Flanks B | ≤4.0 μm | ≤16 μm |
Note: It is recommended to have 50% to 90% of the working surface value.
Installation
Easily assembled into one piece piston. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation all individual parts of the seal must be oiled with system oil.
Permissible sealing gap
| pressure (bar) | 100 | 150 | 250 | 400 |
| Smax (mm.) | 1,00 | 0,80 | 0,70 | 0,60 |
Note: The largest sealing gap value occurring on the non-pressurized side of the seal is vital for the function and in this respect it is quite important to use the S value lower than the above indicated numbers.
We can also produce this piston seal on request in the materials below. This is our type DK102-R.
