Speed:= 0,5 m/s
Fluids:Hydraulic fluids (mineral oil based), water emulsions
Compression strength: 270 N/mm²
Friction coefficient: 0,25
Calculating radial load
FR = (D x L x q / v )x n
FR= maximum radial load (N)
q = compression strength at operating temperature for the given compound (N/mm)
D x L = diameter x seal width (mm)
n = number of rings
v = confidence coefficient (recommendation> 3)
Materials
Phenol resin and synthetic fabric laminated together as layers. This structure guarantees high torsion strength and elasticity. Including PTFE gives better gliding properties (Krütex200). Dimensional accuracy is improved by extremely low water absorption properties of the material (< 0,1%).

Advantages
- High mechanical durability
- High temperature resistance
- High wear and aging resistance
- Easy to assemble
- Low friction
- High weight-carrying capacity
- High surface harness
Cord length
Cord length: A = 3,14 x B - M
- Gap M from table
- B = guide rings effective diameter
- Piston B = øH - L
- Rod B = øH + L
- L = Depth of housing

Installation
The guide ring is stretched open when assembled into the groove
Attention!
The gap behind the seal is chosen seal specifically according to operating conditions.
