NTS3_S series

Robot hand

3-jaw parallel gripper - NTS3_S series

High-quality, highly durable standard 3‑jaw gripper with an integrated measuring function

With a built-in scale, it enables diameter measurement (external/internal diameter) through three-point gripping of the workpiece.
High gripping force for stable gripping of heavy work piece
Improved gripping accuracy due to highly rigid body

How to order

Please install a check valve in the air-pressure circuit so that the gripper will not release a workpiece even if the air pressure drops down.

Gripping force

Click the model number and the gripping force diagram will be displayed. The gripping force, F is a product of the actual gripping force per jaw, F1 and the number of jaws

NTS307S
NTS309S
NTS311S

The gripping force will be calculated by the gripper model, air pressure, and other gripping conditions.
