Vektek Low Pressure 7MPa Catalog

TuffCam ™ 7 MPa Swing Clamps

Clevis Plunger Bottom Flange

Double Acting n All left or right swing clamps swing 90°. Clamps available in 6 retract capacities ranging from 2.2 kN to 24.1 kN. Designed to operate at 7 MPa. n Use double ended Rocker Arms to apply equal force on two surfaces of different heights. n Allowable arm travel for work piece height variation is ± 10° n Two standard arm orientations available (0° and 90°). Request other arm orientations through Vektek. 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 Choose manifold mount above or below the flange or plumb the device. n Tungsten-Carbide cam followers for strength and wear. n Clocking feature for the TuffCam™ 7 MPa at the end of Section C. n Arms sold separately in Section D. 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 retract capacities are listed at 7 MPa (70 bar) operating pressure. Divide cylinder retract force by 2 for when using symmetrical length arm. 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 retract force for your application. (Actual force will vary slightly due to internal 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 per table at the start of Section C. **** In The Port valves require the use of manifold mount ports.
