VersaCam™ Swing Clamps and Arms
Features, Patented Design
VersaCam™ Features Large ball and cam rotational mechanism assures the swing action. Standard swing is 90°; swing angles of less than 90° require Swing Restrictors. Swing 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. Special wipers and swept-line cylinder top helps keep chips from packing and coolant contaminants from entering the operation. cylinder a place to "breathe" and it helps keep chips and coolants from drawing past wipers (unclamp port on double-acting models). Vent port with bronze filter gives the
Exclusive BHC™ (Black Hard Coating) on the cylinder bodies and rod bearing surface helps prevent leaks caused by scoring and scratching. This is especially true in the event of high side or "kick loads" which promote excessive scoring in many other brands. BHC™ gives a Rockwell 60C skin hardness. Hardened 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.

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 or longest swing clamp life) than other clamps. Lasts longer and withstands operator induced "crashes" with less damage from improperly loaded parts. n VersaCam ™ Swing Clamp models
CAM FOLLOWER BALL SEAT
V-groove provides larger surface ball to cam contact area in the event of a crash. n V-groove withstands swing interference better than other cam designs. Vektek again changes the "state of the art"
in ball and cam swing clamps making them work better at reasonable prices.

- Reduced static friction for improved clamp breakaway. - Reduced dynamic friction for improved cam life.. - Keeps cam follower centered in cam track for improved contact.
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.

- 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.
