Swing Clamps and Arms
Bottom Flange Low Profile Clevis
TuffCam Bottom Flange Low Profile Clevis Swing Clamp Use double ended Rocker Arms to apply equal force on two surfaces of different heights. Maximum allowable arm travel for work piece height variation is ±10°.
Manifold and SAE mounting capability. One piece body construction reduces potential leak paths and improves rigidity. 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. Pin, retaining rings, and centralizer springs included. See Clevis Arms on page C-54.

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 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 system hydrauic pressure. To determine the approximate output force for your application divide the cylinder capacity shown above by 5000 and multiply the resultant number by your system operating hydraulic 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 hieght 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 Rates Chart for TuffCam. **** In-port valves require the use of manifold mount ports.

All ports (except breather) are shipped with removable steel plugs installed. Manifold mount counter bores for Ø7/16 x 1/16 (2-011) o-ring. O-rings are provided.
**
*** When manifold mounted all (4) mounting bolts must be used to assure a proper o-ring face seal. Recommended bolt in column AF.
