• Large ball and cam rotational mechanism assures the swing action
• Standard models swing 90°, swing angles of less than 90° readily available for a small additional charge, swings of more than 90° are special order products
• The original "duck billed," cross bolt locking, top cap screw arm design, as originated by Vektek, is highly recommended due to its low mass, versatility, and ease of modification.
• Special wipers and swept-line cylinder top helps keep chips from packing and coolant contaminants from entering 
  the operation
• Vent port with bronze filter gives the cylinder a place to "breathe" and helps keep chips and coolants from drawing past wipers (Unclamp port on double-acting models)
• Exclusive BHC™ (Black Hard Coating) on the cylinder bodies and rod bearing surface helps prevent leaks caused by scoring and scratching especially in the event of high side or "kick" loads which promote excessive scoring in many other brands. BHC™ gives a Rockwell 60C skin hardness
• Chromed and hardened alloy steel plungers run longer with less wear and drag than other brands
• Proprietary seal designs reduce leakage and increase seal life for longer lasting, more dependable operations

• V shaped design provides a tougher mechanism. The ball runs deep in the track eliminating cam to ball edge loading
• Resists flow related damage (Please follow recommended flow rates for longest swing clamp life)
• Lasts longer and will withstand operator induced "crashes" from improperly loaded parts with less damage
• Provides larger surface ball to cam contact area in the event 
  of a crash
• Will withstand swing interference better than other cam designs
• Standard swing clamp models have hardened V-cam tracks that resist damage and give you a built in extra cam (opposite swing direction) or straight line option should you accidentally 
  damage one
• Low profile swing clamps have double V-cams providing extra strength, but must be ordered in the required swing direction. Low profile 22 kN and 33 kN size swing clamps do not have built in multiple direction cams
• Vektek again changes the "state of the art" in ball and cam swing clamps making them work better at reasonable prices

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 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 shown above by 350 bar (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.)

** 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 to the level indicated in theClamp Time and Fluid Flow Rate chart.
