Servo flexible, SFS

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.

(i)Caution

Some of the items are scheduled to be discontinued as of end of March in 2023. The manufacturer keep the items produced but they are not available with Misumi.
There are not the replacement items and the plan to resumption of sale. Please check the quotation and order screen for details.
