Link Clamps
Pneumatic Link Clamps
Double Acting
- Excellent alternative to swing clamps when swing space is limited.
- Available in three sizes: 1, 1-1/2, and 2-1/8 inch bore.
- Top Flange body mount.
- Left, forward, or right lever position from the same body.
- Link clamps clear large obstructions better than other types of clamps.
- Manifold mounted or standard plumbed using standard NPT fittings.
- Standard and Extended levers sold separately.
* Equal to ±3° with standard lever.
** Use of extended length arms will result in a reduction of clamp capacity. See graphs of lever output curves for clamping force of various arm lengths. The clamping force is adjustable by varying the pneumatic system pressure. To insure maximum service life and trouble-free operation, these devices should be positioned in no less than 1/2 second. These recommendations apply when using the standard arm. When using the optional long arm or your custom arm, please restrict the flow rates to position the arm in no less than 1 second.
*** Per complete cycle.
Operating Pressure Range: 30-250 psi
Fluid: Clean Dry Air
Lubrication: Not Required
Levers are to be adjusted to within ±3° of nominal clamp angle to prevent premature failure.
