Rotaly Table, Gripper

In addition to linear components, THK also offers rotary tables and grippers. These can be seamlessly integrated with THK's linear product lineup and easily operated in combination with THK's controller

Rotaly Table, Gripper
ET (Rotaly Table)

The THK Electric Rotary Table ET combines a cross roller ring and hypoid gear to achieve a repeatable positioning accuracy of ±0.04 degrees. Its slim, compact design supports multi-point positioning, continuous rotation, and speed control, with flexible top, bottom, and side mounting options. Compatible with both servo and stepping motors, it can be easily operated when paired with a THK controller.

EG (Gripper)

THK's Electric Gripper EG delivers smooth, high-rigidity operation through its integrated LMGuide, achieving a repeat positioning accuracy of ±0.01mm. It supports multi-point positioning, speed control, and gripping force adjustment, while maintaining grip even when power is cut. Compatible with both servo and stepping motors, it is widely used as an end effector for articulated and Cartesian robots.

Features

ET Table

ET Table Structure

By integrating the cross roller ring and hypoid gear into a unified rotation mechanism, the rotary table and motor are compactly housed, achieving a slim design with a reduced overall height. This integrated structure contributes to space savings in equipment while also maximizing rotational accuracy.

Mechanism Realizes High Rotational Accuracy

Combining our proprietary cross roller ring with a hypoid gear achieves a highly precise rotation mechanism — a structure only possible because THK has been a manufacturer of cross roller rings.

EG Gripper

EG Gripper Structure

The drive structure efficiently transmits motor output through LM guides, achieving both smooth motion and high rigidity. By combining a small-lead sliding screw with a reduction mechanism, it delivers a repetitive positioning accuracy of ±0.01mm and stable gripping force, even with a compact motor.
