Product Description

Rotary gripper suitable for holding and reversing workpieces on transfer lines.
[Features]
· Compact integration of gripping with rotation functions.
· Eliminates whirling of the piping and wiring caused by combining individual products (rotary table + adapter + air gripper).
· Compared with combined products, the longitudinal dimension is approximately 20% shorter.
· 2 types of angle rotation (90° and 180°) are now standard.
· Auto switches can be retrofitted using the magnet (equipped as standard).

Chuck Rotation Range / View from Chuck Side

The figure on the left indicates the position of the chuck when pressure is applied to port B.
When pressure is applied to port A, the chuck rotates clockwise.
Adjusting bolts allow the rotation range of the gripper unit to be adjusted by ±5° at both ends of rotation.
