Krütex Rod Guide Rings

Operating conditions

Krütex 200                       Krütex 100                  

Temperature:                    -50°C....+130°C                -50°C....+120°C

Speed:                             ≤ 1.0 m/s                           ≤ 0,5 m/s

Friction coefficient::          0,05                                    0,25

Compression strength:     340 N/mm²                       270 N/mm²

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%).

Cord length

Cord length: A = 3,14 x B - M

- Gap M from table

- B = guide ring’s 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.
