E-Catalog > VEKTEK USA > Metric TuffCam Swing Clamps

TuffCam™ Swing Clamps meet your demand for a product that can handle the stress and positioning requirements of high-speed or heavy arm applications. These tri-cam design clamps, with their patented Cam Follower Seat, can position and clamp in one second or less, handle large arms with ease and include the Clockingfeature that dramatically reduces the time it takes to change arms for maintenance, replacement or fixture setup.

• Single and double acting devices available.The Low Profile Single Acting models have increased spring forces for positive return in higher backpressure applications.
• Three cams for more accurate arm positioning, smoother rotation and lower per cam surface contact pressure.
• Vektek again changes the "state of the art" in ball and cam swing clamps making them work better at reasonable prices.
• Patented ball seat for improved rotary function, cam follower contact, and reduced dynamic and static friction.
• Standard fluorocarbon wipers improve coolant compatibility.
• Both TuffCam and TuffCam Low Profile include theClocking feature that uses standard Vektek arms.
• Same mounting envelope as standard VektorFlo^®swing clamps.
• BHC™ (Black Hard Coating) on the cylinder bodies helps prevent scoring and scratching

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

** Cylinder capacities are listed at 350 bar (35 MPa) maximum operating pressure, with a standard length VektorFlo^® arm installed. Minimum operating pressure is 52 bar (5,2 MPa) for single acting, 35 bar (3,5 MPa) 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 350, and multiply the resultant number X 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 work piece height variations, it is recommended that the vertical travel be set to 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 Flow Rate Chart.

Cylinder capacities are listed at 350 bar (35 MPa) maximum operating pressure with a standard VektorFlo^® arm installed. See the Arm Length and Pressure Limitations graph for clamping force with various other arm lengths installed.  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 graph by 350 (35 MPa), 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.
