SPG-1 is a two piecedouble acting piston seal which consists of one energizing elastomer ring and special mixture thermoplastic ring.
PRODUCT ADVANTAGES
- Low firction , free stick-slip
- Excellent performance in large diameter cylinders and heavy duty applications
- Long service life
- High sliding speed
- Wide range of temperature and chemicals depending on the o-ring material
- Minimum static and dynamic friction coefficient for a minimum energy loss
- Simple groove design and low axial housing heights
- No twisting in the housing
APPLICATION
Steel industry , injection moulding machines , presses , large diameter cylinders , steel industry
| MATERIAL | |

| NBR | 80 SHORE A |
| OPERATING CONDITIONS | |
| MEDIA | Mineral oils (DIN 51524) |
| TEMPERATURE | -30°C +105°C |
| PRESSURE | ≤400 Bar |
| SPEED | ≤5.0 m/sn |
Note: The above data are maximum values and cannot be used at the same time. For HFA HFB HFC used applications , special filled PTFE materials are recommended. Resistance in low temperature and high temperature applications can be improved by alternate elastomer compounds.
| SURFACE ROUGHNESS | Ra | Rmax |
| Sliding Surface Ød | ≤0.2 μm | ≤2.0 μm |
| Groove Base ØD | ≤1.6 μm | ≤6.3 μm |
| Groove Flanks B | ≤3.2 μm | ≤16 μm |
Note: It is recommended to have 50% to 90% of the working surface material contact area value.
INSTALLATION
We recommend using special assembly tool (See section; Hydraulic Sealing Elements General Installation Information). 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.
NOTES For special applications that require high temperatures , rod seal is manufactured in FKM and PTFE material.
