WARNING! Never allow swing arm to contact workpiece or fixture during rotation. * Cylinder capacities are listed at 350 bar (35 MPa) maximum operating pressure with standard length VektorFlo® arm installed. Minimum operating pressure is 52 bar (5.2 MPa) for single acting cylinders and 35 bar (3.5 MPa) for double acting cylinders. The clamping force is adjustable by varying the system hydraulic pressure. To determine the approximate output force for your application, divide the cylinder capacity by 350 (35 MPa), 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 spring forces.)** To allow for piece part height 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 according to the Clamp Time and Fluid Flow Rates.**** In-port valves require the use of manifold mount ports.

Single And Double Acting Three cams and three cam balls guide the rotation of the plunger and provide greater guide, support and directional stability. Ideal for applications where speed is essential or massive arms are required. Low profile swing clamp arm details are found in Section 0. To avoid cylinder damage and preserve warranty, use recommended flow rate limits and time calculations in Section C.Arm clocking feature is compatible with all standard Vektek arms. Clocking drawing is in Section C. High clamp force capacity in a compact package. Manifold mounting capability and G Series porting. Arms sold separately - See Section O.Standard swing is 90°; swing angles of less than 90° require Swing Restrictors. Swing angles greater than 90° are special order products. 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.

n Three cams for more accurate arm positioning, smoother rotation and lower per cam surface contact pressure. n Patented stainless steel ball seat for improved rotary function, cam follower contact and reduced friction.

n Increased cam groove contact force provided by stainless steel spring.n Ball material of Tungsten carbide, one of the world's hardest materials.

TuffCam™ Low Profile Swing Clamp Cam Follower Design

TuffCam™ Low Profile Swing Clamps Vektek’s TuffCam™ Low Profile Swing Clamps meet your demand for speed, precise positioning, heavy arm applications and/or clamping capacity up to 33 kN. These Low Profile tri-cam design clamps, with their exclusive Cam Follower Seat, can position and clamp in one second or less and handle large arms with ease. Each clamp includes the Clocking Feature that dramatically reduces the time it takes to change arms for maintenance, replacement or fixture setup. One of the keys to this TuffCam™ innovation is the patented CamFollower Ball Seat that was developed to improve strength and wear. Usingthe Vektek V-Groove technology, a tungsten carbide ball and a stainless steelspring, these clamps have reduced static friction for improved clamp breakaway and extended life.

* Tougher Cams* Stronger Single Acting Springs* Precise Swing Angle* Clocking

n Available in these body styles:- Top Flange

- Top Flange Long Stroke (Double Acting Only) - Bottom Flange - Low Profile Rod Position Sensing - Low Profile Magnetic Position Sensing

n Single and double acting models available. The Single Acting models have increased spring forces for positive return in higher back pressure applications. n BHC™ (Black Hard Coating) on the cylinder bodies helps prevent scoring and scratching.n Standard fluorocarbon wipers for improved coolant compatibility.n Arm clocking feature uses standard Vektek arms.

CLAMPPOSITIONTuffCam™ Low Profile Clocking Feature

We have added 3 clocking features to Vektek’s Low Profile Swing Clamps. Customers have requested the clocking features to help improve and speed-up arm changes. A drill point on each clamp standardizes arm location at a particular position. An additional 2 (two) orientation drill points reside 120° out from that position and each other. Access to the positioning feature is through the back or side of the arm, making modification a snap for users. Each arm position can have its own specification.

The flows listed are maximum recommendations and clamp times are minimum recommendations.- For upreach, and double arms, use extended arm time and flow.- When using custom arms, the extended arm flows and times are to be considered the limiting factor. However, the actual time in which the clamp can be positioned will vary by custom arm configuration and may require customer testing in specific application to establish limits.

TuffCam™ Low Profile Swing Clamp Arm Clocking Feature

Views shown apply to Double and Single Acting TuffCam™ Top and Bottom Flange models.�

Three counter sunk Ø 4.8 x 90° clocking feature drill points are shown in the clamped position.�

The three clocking features are equally spaced 120° apart.
