SSB is a two piece single acting buffer seal which consists of onespecial designed elastomeric sealing element for to evacuatethe back pressure and one thermoplastic back-up ring.
PRODUCT ADVANTAGES
- No pressure build up between the primary and secondary seal
- High wear resistance
- Low friction
- Low axial housing heights
- Good protection to the secondary seal with pressure peaks
APPLICATION
Construction machinery , fork-lift trucks , injection mouldingmachines , agricultural machinery , cranes , earth movingequipment and standard cylinders.

| 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
Easily assembled into closed grooves. 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 SSB buffer seal is always used in a sealing system in combinationwith u-ring (K22 , K33 , etc) as they are not designed as being themain sealing element. SSB reduces the pressure peaks on itself inorder to save the main sealing element with pressure fluctuations.

Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.
