TuffCam ™ Swing Clamps
TuffCam ™ Low Profile Clocking
TuffCam™ 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.

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.
Clamp Time and Fluid Flow Rates for TuffCam™ Swing Clamps
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.
