NFS

Product Information

Clamping arm swing right or left, then clamping on straight line to hold the workpiece.
The cylinder body material is carbon steel, the surface is hard mebrane treated.
Suggested to add a flow control valve to the hydraulic inlet to control the motion of the swing angle in order to prevent the inertial impaction.
A workpiece should be clamped within up-down clamping stroke, not swing stroke.
When load and unload the workpiece, it is necessary to use an air gun to clean the piston and the seal for removing iron slag or other junk. In order to prevent the junk enter into the seal to cause oil leakage.

Max. operating pressure: 210 kgf/cm²
Min. operating pressure: 70 kgf/cm²
Single acting and Double acting.
NOTE:
The acting speed of clamping-unclamping should be slowed down.
For customized clamp arm, please don't exceed 1.5 times of the original length and weight.
The methods to mount & remove and the rotation diagram of the clamp arm, please refer to Q&A.
Orders with customized request are available, welcome to contact us.

Usable fluid:
General Hydraulic Oil Equivalent to ISO-VG-32.
