Versatile and 2-Jaw Pneumatic Parallel Multi-Tooth Gripper with Multiple Sensor and Pneumatic Interfaces
Outstanding Performance
The TWN grippers feature high precision, permanent lubrication, multi-tooth design, and straight groove guidance.
The compact structure is suitable for short strokes and heavy loads.
The load is distributed across more surfaces, reducing contact stress.
Grease is distributed more efficiently and evenly.
The design ensures long-lasting motion rigidity and accuracy.
The multi-tooth guide's oil storage structure enhances service life.
The TWN grippers offer a variety of sensor and pneumatic interface options.
Gripping Force Maintenance – AS/IS
The TWN grippers can be equipped with gripping force maintenance, available in the expanded TWN-P-AS/IS (AS: closing maintenance, IS: opening maintenance).
A spring functions as the holding accumulator, ensuring that a minimum clamping force is maintained in the event of a pressure drop.
Dust-Tight Version
The TWN grippers can be upgraded to a dust-tight version, expanded to TWN-SD, with an IP64 rating.
High-Temperature Version
The TWN grippers can be upgraded to a high-temperature version, expanded to TWN-P-HT, with a temperature tolerance range extended from 5/90°C in the basic version to 5/130°C.
