Swing Clamps and Arms
Features, Patented Design and Air Ordering
VersaCam™ Features Large ball and cam rotational mechanism assures the swing action. Standard swing is 90°; swing angles less than 90° require Swing Restrictors (Page C-32). Swings angles greater 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, see end of Section C. Special wipers and swept-line cylinder top help 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
n Will withstand swing interference better than other cam designs. n VersaCam™ 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. Vektek changes the “state-of-the-art” in ball and cam Swing Clamps making them work better at reasonable prices. or “kick” loads which promote excessive scoring in many other brands. BHC™ gives a Rockwell 60C skin hardness. Hardened chrome 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. 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

Patented V-groove Cam Design V shaped design provides a tougher mechanism. The ball runs deep in the track eliminating cam to ball edge loading. Resists flow related damage better (Please follow recommended flow rates for longest Swing Clamp life) than other clamps. Lasts longer and will withstand operator induced “crashes” from improperly loaded parts with less damage. Provides planar rather than edge contact with the cam follower.

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