Krütex 200 Temperature: -50°C ...+130°C Speed:= 1.0 m/s Fluids:Hydraulic fluids (mineral oil based), water emulsions Compression strength: 340 N/mm² Friction coefficient: 0,05 Krütex 100 Temperature: -50°C ...+120°C 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. |
