MST/MSTS flexible coupling slit type

MST/MSTS flexible coupling slit type

Backlash "0." Design of aluminum alloy slit pattern changed to improve performance.

[Features]
· Metal spring coupling with perfectly integrated structure, with slit in cylindrical material.
Leaf spring formed with a slit allows eccentricity, angle deviation, and end play.
· 2 kinds available: aluminum alloy / all stainless steel type.
· Wide range of outer diameters, ø8 to ø63
