High Precision Multi-Tooth Pneumatic Gripper with Force Maintenance
High Precision Multi-Tooth Pneumatic Gripper with Force Maintenance
Outstanding Performance
1.The TWN grippers feature high precision, permanent lubrication, and a multi-tooth straight-groove guide design.
- Compact structure supports short strokes and heavy loads
- Load is distributed across more surfaces, reducing contact stress
- Grease disperses more efficiently and uniformly
- Ensures lasting motion rigidity and positioning accuracy
- Oil-storage structure within the multi-tooth guide extends service life
2. Multiple sensor and pneumatic interface options are available for TWN grippers.
Gripping Force Maintenance – AS/IS
-
TWN grippers support gripping force maintenance and can be extended to TWN-P-AS/IS (AS: closing maintenance, IS: opening maintenance).
-
A spring is used as an energy accumulator to maintain a minimum gripping force during pressure drops.
Dust-Tight Version
TWN grippers are available in a dust-tight version (TWN-SD), achieving protection level IP64.
High-Temperature Version
The TWN grippers can be upgraded to a high-temperature version (TWN-P-HT), increasing the temperature tolerance from 5/90℃ to 5/130℃.
