Metal bellows couplings
MKJ-SAL
MKJ-SAL
- very low mass inertia torque
- easy for assembly
- a small space for assembly
- balanced
- special design available on request
The size of the coupling should be selected so that the nominal torque is greater than the highest torque to be regularly transmitted. (Acceleration or load torque). The shaft misalignments must not exceed the previously mentioned values. Otherwise this will limit the working life of the coupling.
hub material: aluminium alloy
bellows material: high-grade steel
