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 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.)

** 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.

**** In-port valves require the use of manifold mount ports.

Optional in-port flow control is a
meter-in device with reverse free
flow check valve. 

• Three cam sizes available for accurate arm positioning, smoother rotation and lower per cam surface contact pressure.
• Patented ball seat for improved rotary function, cam follower contact and reduced dynamic and static friction.
• Fluorocarbon wipers are standard for improved coolant compatibility.
• Standard swing is 90°; swing angles of less than 90° require Swing Restrictors. Swing angles greater than 90° are special order products.
• Same mounting envelope as standard VektorFlo® MetricSwing Clamps.
• Tungsten Carbide ball material for strength and wear.
• Top flange TuffCam™ swing clamps can be either manifold mounted or standard plumbed.
• Fitting 30-8711-20 adapter assembly included and shipped with the clamp. Plugs are also included and shipped.
• 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.
• TuffCam™ Clocking feature uses standard Vektek arm.
• Arms Sold Separately.

BHC™ (Black Hard Coating) on the cylinder bodies helps prevent scoring and scratching.

For proper sealing, the mating surface
must be flat within 0.08 mm
with a maximum surface roughness
of 1.6 mµ Ra
