By using KALLER gas springs instead of traditional coil and rubber spring elements, several benefits are obtained.
The benefits are:
Compact - high spring force in less space/height
Adjustable force
Controllable
Large initial force
Low force build up
Pre-loaded
Life Cycle Cost savings
The gas springs in the KALLER Gas Spring range can be divided into two main
groups: Piston rod sealed and bore sealed gas springs.
