Superior Performance
-
TWN grippers feature high precision, permanent lubrication, multi-tooth design, and straight groove guidance.
-
The compact structure is ideal for short strokes and heavy loads.
-
Load distribution across multiple surfaces reduces contact stress.
-
Grease is dispersed more efficiently and evenly.
-
Ensures long-term motion rigidity and accuracy.
-
The oil storage design within the multi-tooth guide extends service life.
-
TWN grippers offer multiple sensor and pneumatic interface options.
Gripping Force Maintenance – AS/IS
-
TWN grippers can be equipped with gripping force maintenance, expanded to TWN-P-AS/IS (AS: closing maintenance, IS: opening maintenance).
-
A spring serves as the holding accumulator, ensuring a minimum clamping force is maintained in case of a pressure drop.
Dust-Tight Version
TWN grippers can be upgraded to a dust-tight version, designated as TWN-SD, achieving an IP64 rating.
High-Temperature Version
TWN grippers can be upgraded to a high-temperature version, designated as TWN-P-HT, increasing the temperature tolerance range from 5–90°C in the standard version to 5–130°C.
