TuffCam™ 7 MPa Swing Clamps
TuffCam ™ 7 MPa Swing Clamps
Three cams for more accurate arm positioning (90° ± 3° swing accuracy) (±0.25° contact position repeatability). 7 MPa swing clamps are designed to work at any pressure between 1 MPa (10 bar) and 7 MPa (70 bar) using either the standard or extended length arms without the need for pressure reduction. Patented ball seat for improved rotary function, cam follower contact and reduced dynamic and static friction. Tungsten Carbide balls. BHC™ (Black Hard Coating) on the cylinder bodies helps prevent scoring and scratching. Clocking features help to improve and speed-up arm changes. (See the end of Section C.) For swing restrictors, see the end of Section C. Arms ordered separately.
TuffCam™ 7 MPa Swing Clamps were developed to meet your demand for high-speed, precise positioning and/or heavy arm applications in a 7 MPa operating pressure environment. One of the keys to this innovation is the patented spring loaded TuffCam™ design that was developed to improve strength and wear. Using the patented Vektek V-Groove, a stainless steel ball seat, these clamps have reduced static friction for improved clamp breakaway and reduced dynamic friction for improved life. This combination adds up to producing the most accurate and repeatable swing clamp cam assembly. Available in 6 sizes from 1.9 kN to 20.4 kN at 7 MPa (70 bar), in Top Flange and Bottom Flange body styles. Double acting.

Excess weights may require slower speeds and customer testing in specific application to establish limits.
Cam Follower Ball Seat
7 MPa TuffCam™ Swing Clamp Cam Follower Design * Three cams for more accurate arm positioning, smoother rotation and lower per cam surface contact pressure. * Stainless steel ball seat for improved rotary function, cam follower contact and reduced friction. * Increased cam groove contact force provided by stainless steel springs. * Ball material is tungsten carbide - one of the world’s hardest materials.
