Hollow Rotary Table Feature Overview

Dynamic balanced clamp ring mechanism

Error-Free installation and the balanced clamping system allows higher input speeds and no backlash for power transmission.

Universal mounting motor flange

Allows quicker delivery and easier mounting to any stepping motor and servo motor.

High torque & low backlash

Helical gear type planetary gearing.
Improvement of wear resistance by gear heat treatment.

Increased service life

Full complement needle planet bearings. (Solid uncaged needle roller bearings)
