TuffCam™ Swing Clamps were developed to meet your demand for a product that can handle the stress and positioning requirements of high-speed or heavy arm applications. These tri-cam design clamps will position and clamp in less than one second and handle larger arms than standard swing clamps. One of the keys to this innovation is the patented Cam Follower Ball Seat that was developed to improve strength and wear. Using the patented Vektek V-Groove, a composite ball seat, and an elastomer spring, these clamps have reduced static friction for improved clamp breakaway and reduced dynamic friction for improved life.
