Type K25V and K35V
For small engines and generator sets with 1 or 2 cylinders
These flexible mountings contain a special rubber compound with excellent vibration damping properties. They are suitable for marine engines in the power range between 4 and 15 kW (6-20 hp).

Type K40A
For 3-cylinder marine diesel engines
Type K40 has a relatively soft, rubber compound which fulfils the requirements of light-weight vessels with a modern 3-cylinder marine diesel engine. The rubber elements create an optimum in vibration dampening. Type KSTEUN40 features internal buffers which limit the engine movements when started or stopped. It is also secured against overload and shearing off.

Type K50V/75V/80V/100V
For smaller engines up to ± 60 kW (80 hp)
This type is suitable for smaller engines up to approximately 60 kW (80 hp).
