TuffCam Low Profile Top Flange Inch Hydraulic Swing Clamps

5,000 lbs Capacity – Straight Pull Available in all models!

Catalog Section

Single Acting models have increased spring force for positive return in higher backpressure applications.
Manifold and SAE mounting capability.
See the Swing Clamp Arm page for all Low Profile Swing Clamp Arms.
One piece body construction reduces potential leak paths and improves rigidity.
Avoid cylinder damage and preserve warranty by following the Clamp Time and Fluid Flow Rate chart.
Tungsten Carbide ball material for strength and wear.
TuffCam™ Low Profile Clocking feature is compatible with all standard Vektek arms.
BHC™ (Black Hard Coating) on the cylinder bodies helps prevent scoring and scratching.
Optional In-Port flow control is a meter-in device with reverse free flow check valve.
Optional In The Port Sequence Valve is a sequencing device with reverse free flow check valve.

WARNING! Never allow swing arm to contact workpiece or fixture during arm rotation.

*Cylinder capacities are listed at 5000 psi maximum operating pressure with a standard VektorFlo® arm installed. Minimum operating pressure is 750 psi for single acting and 500 psi for double acting. The clamping force is adjustable by varying the hydraulic system pressure. To determine the approximate output force for your application, divide the cylinder capacity from the chart above by 5000 psi, and multiply the Resultant Number times Your System Operating Pressure to obtain the approximate clamping force for your application. (Actual force will vary slightly due to internal cantilever loading, friction loss and/or return springs.)
**To allow for piece part height variations, it is recommended that the vertical travel be set at about 50% of the vertical stroke.
*** To insure maximum service life and trouble-free operation, restrict fluid flow to the level indicated in the Clamp Time and Fluid Flow Rate chart.
**** In-port flow control requires the use of manifold ports.

* All ports (except breather) are shipped with a removable steel plug installed.
** Manifold Mount Counter bores for Ø7/16 X1/16 (2-011) O-ring face seals provided.
*** When used as manifold mounted, all (4) mounting bolts must be used to assure proper O-ring face sealing. Recommended bolt in column AF.

For proper sealing, mating surface must be flat within 0.003 in. with a maximum 63 µ in R_a surface finish.
