TuffCam ™ 7 MPa Swing Clamps
Bottom Flange Swing Clamp
Double Acting n Six clamp capacities are available ranging from 1.9 kN to 20.4 kN. n TuffCam™ 7 MPa Swing Clamps are designed to operate from 1 MPa (10 bar) to 7 MPa (70 bar) without pressure reducing. n 7 MPa Clamps and work supports are paired to work at pressures between 4 MPa (40 bar) and 7 MPa (70 bar) without pressure reducing the clamp. n Clamp repeatability ±0.25° and swing angle repeatability 90° ± 3°. n Consult table at the start of Section C for clamp time and fluid flow rates. n Patented ball seat delivers improved rotary function, cam follower contact, while reducing dynamic and static friction. n Can be either manifold mounted or plumbed. n Tungsten-Carbide ball material; one of the world’s hardest materials. n Clocking feature for the TuffCam™ 7 MPa at the end of Section C for repeat locating of arm. n For swing restrictors, see the end of Section C. n Arms sold separately in Section D. Short arm threaded contact bolt hole is designed to clamp over the work support centerline. n Optional In The Port flow control is a meter-in device with a reverse free flow check valve. n Optional In The Port sequence valve is a pressure 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 7 MPa (70 bar) operating pressure, with a standard length VektorFlo ® 7 MPa arm installed. Maximum operating pressure is 10 MPa (100 bar). The minimum operating pressure is 1 MPa (10 bar). 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 7 MPa (70 bar), and multiply the resultant number by your system operating pressure MPa (bar) to obtain the approximate clamping force for your application. (Actual force will vary slightly due to internal cantilever loading, and/or friction loss.) ** 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 at the start of Section C. **** In The Port valves require the use of manifold mount ports.
