The sleeve's internal/external diameter ratio is small. The mounting part's diameter as well as the moment of inertia can be reduced. The mechanism is simple and high concentricity can be maintained.

■ SMA MODEL

SMA models employs counter lock in inner ring and is good in centering.

A simple structure and rigid parts provide uniform transmission and can withstand heavy load. A short shaft direction length saves space.

This is designed for a medium load. The contact pressure is small and the mounting diameter and mass can be reduced. A short shaft direction length saves space.
