General Information

1. If users want to change the length of the single arm of a clamping cylinder, it should be noted that the length must be less than 1.2 times G value in order to avoid the serious slanting of the piston rod. If the length in design needs to be larger han the aforesaid limit value, it is better to use products having double arms in order to extend the use life of the cylinder.

2. When using double/single arms of which the lengths are very long, it is necessary to consider whether the weight of the clamping arm is too heavy or not, and to use a throttle to appropriately slow down the flow rate of the air/oil in order to avoid the damage of the swing mechanism due to the inertia of the clamping arm. Further, it should not directly apply the unadjusted air pressure to the hydraulic swing clamp cylinder.

3. Workpiece should not be clamped within a swing stroke during the downward pressing of the clamping arm, and should be clamped within the vertical stroke; otherwise, the cylinder will be seriously damaged.

4. During the loading and undoading of a workpiece, it is necessary to use an air blower to clean the piston and the seal for removing the iron slag or foreign objects attached thereon in order to prevent the foreign objects from entering the seal to cause oil leakage.

5. When using the pneumatic cylinder, it is necessary to use a device having F.R.L.* function and a throttle in order to effectively remove the moisture, lubricate the cylinder and avoid the damage of the swing mechanism  due to the inertia impact of the clamping arm in order to extend the use life of of the cylinder.

6. If the direction of the single arm needs to be changed due to the problem of piping, it should use a wrench to fix the clamping arm first, and then unscrew the screw and knock the clamping arm upward to change its direction. It should not apply the lateral force to the clamping arm or laterally impact the clamping arm, which
should be also noted when locking the clamping arm in order to avoid the damage of the swing mechanism due to improper forceapplied thereon.

7. The theoretical clamping force is derived from the formula : F= P x A. In fact, the friction must be taken into consideration; further, it should take the loss due to the restoring force of the spring into consideration when using single-acting cylinders. In general, the actual clamping force is 85%(just for reference) of the theoretical
clamping force.

8. The direction of the swinging is directed to the direction of the downward pressing of the clamping arm, including clockwise direction(Right) and counterclockwise direction(Left), which will be marked on the label onthe cylinder.

9. The Power source should not exceed the rated maximum pressure and the highest flow value.
*F: Filters, R: Regulators, L: Lubricators



FEATURES:
The clamping cylinders are used when machining a workpiece by means of a machine tool in a restricted area.

The clamping cylinders are double-acting pull cylinders
with a total stroke of swing stroke plus clamping stroke.

The clamping cylinders are available at four or five standard sizes with clockwise and counterclockwise swing. The mounting types include flange and threaded
types.


NOTES:
If a longer clamping arm is desired, please keep the length of clamping arm within 1.2 times of that of the standard clamping arm.

When a longer clamping arm is used, please reduce the operating pressure as appropriate.

Installation of a flow control valve is recommended so as to protect cylinder body and internal components.
