3 Pieces | NBR + NBR/fabric + POM | ≤400 | -30 to +100 ºC | ≤0,50 m/s |
Quick LINKS
3 PIECES PISTON SEAL
Compact seals which have a widespread use are used as double acting sealing elements in hydraulic cylinders’ piston applications.
Three-piece double-acting compact seals consist one fabric reinforced elastomeric sealing element, which allows a high mechanical strength, and two thermoplastic guide rings. The set withstands abrasion very well.
ADVANTAGES
- Low friction, free of stick-slip effect
- Improved abrasion resistance
- Good dynamic and static sealing effect
- Long service life
APPLICATIONS
Mining equipment , iron and steel industry , marine hydraulics andearth moving equipment.
WORKING CONDITIONS
Media | Mineral oils (DIN 51524) | HFA and HFB | HFC |
Temperature | -30 °C to +105 °C | +5 °C to +60 °C | -30 °C to +60 °C |
Pressure | ≤400 Bar | ≤400 Bar | ≤400 Bar |
Speed | ≤0,5 m/sn | ≤0,5 m/sn | ≤0,5 m/sn |
Surface roughness | ||
| Ra | Rmax |
Sliding surface | ≤0,4 μm | ≤3,2 μm |
Groove base | ≤1,6 μm | ≤6,3 μm |
Groove flanks | ≤3,2 μm | ≤16,0 μm |
Note: It is recommended to have 50% to 90% of the working surface material contact area value.
INSTALLATION
Three-piece piston seal profile has been designed for its installation in closed or open grooves taking the indicated catalogue information into consideration. We recommend having open groove design for dimensions that are smaller than Ø50 mm. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.
For special applications that require high temperatures ,piston seal set can be manufactured with reinforced cotton fabric + FKM and PTFE guide rings.
