Servo couplings / pilot bore, core bore, internal thread / 1 disc: steel / body: steel / SFS / MIKI PULLEY (Part Numbers - CAD Download)

Servo couplings / pilot bore, core bore, internal thread / 1 disc: steel / body: steel / SFS / MIKI PULLEY

MIKI PULLEY

MIKI PULLEY

Using carbon steel for the main body material, with very precise adjustment and high rigidity.

[Features]
· Torsional rigidity is extremely high, accurate shaft rotation, super precision control is possible.
· Since all power transmission is transmitted by friction coupling, there is no backlash.
· SFS-SS/ DS type is shipped from the factory as an assembled finished product.
