Industrial Shock Absorber / COMPENSER®

With the KL-Type, LEBEN provides a hydraulic industrial shock absorber with spring return for applications in light engineering.

industrial shock absorber spring

The COMPENSER® of the KL series is an industrial shock absorber for light mechanical engineering, e.g. handling equipment, small storage and retrieval machines and small crane systems. Due to the lower resetting force, this buffer of the KL-series is well suited for operation-related push in cycles in creep speed.


  • preferred installation position: vertically, other installation positions are also possible upon request
  • low resetting force
  • very short design
  • high buckling safety
  • surface galvanized
  • low-viscosity COMPENSOL®
  • flange mounting optionally on front or back
  • foot mounting or flange mounting or screw connection with a counter nut
  • optionally constant or variable reaction force along the stroke
  • temperature range -25 to +80° C
  • energy absorption up to 20 kNm

Shock Absorber with SpringThe piston rod 2 pushes the piston 6 into the pressure chamber 7. At the same time, the damping medium flows through the metering grooves placed in the outer tube 8, via the piston 6 and into the volume balance chamber 5. The return spring 3 is tensioned and, after the impact has occurred, pushes the piston rod 2 back to the initial position. By this the damping medium flows back into the pressure chamber 7.
