SFM

A selection of SFF models is available for use by the feed shaft, and a selection of SFM models is available for use by the main shaft.

Two types of couplings, either a high-rigidity type with one element or a high-flexibility type with two elements using a spacer, can be selected respectively.

In particular, the SFM model that has been developed for the main shaft of machine tools allows a maximum rotation speed of 20,000 min-1 and is capable of substantially lowering wind roar during high-speed rotation by the design that lowers the coupling circumference or edge irregularity to the extent possible.

It is mounted by a high-reliability friction lock. Extremely high-precision mounting is realized by using a centering mechanism.
