Product Information

It is not necessary to manufacture a hole for the installing and you just need to use bolt to fix the swing clamp on the fixture plate. It is helpful for you to clamp thick workpiece because the main structure of the cylinder body is on the fixture plate.
Feature of the doubling acting type: Oil circuits control clamping and unclamping, you can control the clamping and unclamping by changing the direction value.
Feature of the single acting type :The design of the interior system is simple. It is not necessary to design for unclamping. It can return back to the original position by spring and the system design is simple because of few accessories.
The material of the cylinder body is carbon steel and treated by nicarbing. The hardness of the outside and inside surface of the cylinder is high and the cylinder is anti abrasive.

Max.operating pressure: 250 kgf/cm²
Min.operating pressure: 70 kgf/cm²
Single acting and Double acting
The action and the speed of clamping / unclamping needs to be slowed down appropriately.
The length and weight of the customized clamping arm shall not exceed 1.5 times of the standard clamping arm.
Please refer to Q&A for the rotation diagram, installation instructions and removal methods of the clamping arm.

Usable fluid:
ISO-VG-32 hydraulic oil equivalent to ISO viscosity grade
