High clamping power for all compact design rail profiles

Process Clamping for Rail Systems, Compact
Holding force 1.300 lbs

Small can clamp perfectly too: the LOCKED-Family PLK clamping elements are more compact than the PL components. They also clamp directly onto the respective linear guide, suit all standard rail sizes from 15 mm to 55 mm (0.65 to 2.17 in) and profiles from the known suppliers and are extremely reliable and space-saving.

Thanks to the patented spring steel plate system, the LOCKED-Family PLK achieves clamping and holding forces of up to 472 lbs (2,100 N) with the shortest reaction times when vented. LOCKED PLK achieve 100% clamping force due to the steel pads that are used, even on greased rails. The clamping elements represent the maximum holding forces. For either the 58 or 87 psi (4 or 6 bar) version, they are good for up to 1 million cycles.
