TuffCam Low Profile Bottom Flange Inch Hydraulic Swing Clamps

Single And Double Acting

Catalog Section

Single Acting models have increased spring forces for positive returning higher back pressure applications.
Manifold mounting capability as well as SAE porting.
One piece body construction reduces potential leak paths and improves rigidity.
Tungsten Carbide ball material for strength and wear.
Arm clocking feature is compatible with all standard Vektek arms.
Low profile swing clamp arm dimensions are found here.
To avoid cylinder damage and preserve warranty use recommended flow rate limits and time calculations.
Optional In-Port Flow Control is a meter-in device with reverse free flow check valve.
Optional In-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 5,000 psi maximum operating pressure, with a standard length VektorFlo® arm installed. Minimum operating pressure is 750 psi for single acting, 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 shown above by 5,000, and multiply the resultant number by 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 to about 50% of the vertical stroke.
*** To ensure maximum service life and trouble-free operation, restrict fluid flow using the Clamp Time and Fluid Flow Rates Chart for TuffCam.
**** In-port flow control requires the use of manifold mount ports.

* All ports (except breather), are shipped with removable steel plugs installed.
** Manifold mount counter bores for Ø 7/16 x 1/16 (2-011) O-Ring face seals provided.
*** When used as manifold mounted, all four mounting bolts must be used to assure proper O-Ring face sealing. Recommended fastener sizes are listed 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.
