3RF-Retractable-Jaw 3-jaw Shaft Chuck

Retractable-Jaw 3-jaw Shaft Chuck

Compensation-Type | 3-JAW

The workpiece compensation of eccentric is 1mm, fixed position for the center, swing and grasp the workpiece to three jaw.
Second machining can be performed without reversing the workpiece, thus significantly reducing setup time.
With compensating jaws clamping, the Rough and precision machining can be carried out.
With sealed design, the maintenance costs can be reduced.
Can be paired with double-rod rotary cylinder (3RF-D type).
The driver pin thrust can be controlled by the pressure of the rotary cylinder (3RF-D type).
