Lead Screws, Nuts, & Hybrid Linear Actuators NEW The nuts are self-lubricating, maintenance free, and require no external lubrication in most applications — resulting in a smooth, quiet operation with no metal-to-metal contact. Constant Force Technology applies a uniform pressure to the nut at all stages of a motion profile and throughout it's life. NUT OPTIONS Constant Force Nut • Greater consistency and resistance to backlash Constant Force screw & Nut Coil Spring Adjustable Anti-Backlash Nut • Configurable for various torque requirements • Patent pending self-adjusting anti-backlash feature FC = Constant Force • Custom solutions available Adjustable coil spring anti-backlash nut • Patent pending coil spring anti-backlash feature Coil Spring Adjustable Nut Coil spring design results in transferred pressure, removing play between the nut and screw. • Two standard mounting options: flange or threaded O.D. • Custom mounting options available Lead Screw Features • 300 series stainless steel with PTFE coating • 6, 10, 12, and 16 mm diameters available • 1, 2, 4, 5, 6, 8, 10, 12, 16, 25 mm leads • Custom sizes, materials, and finishes available Compared to: INTEGRATED HYBRID LINEAR ACTUATORS • Reduced number of components • Eliminate component tolerance stack-up Traditional torsion spring Design Variable twisting spring force can result in loss of pressure on the nut requiring manual adjustment. • Improved rigidity and performance fEATURES & Benefits • External nut type: 3 nut options available • Utilizes Constant Force Technology, adjustable, or machined fixed nut and lead screws • Smooth, quiet, consistent operation • NEMA 17, 23, 34 flange sizes • Single, double, and triple stack motors available PBC Linear, a Pacific Bearing Company • 6402 East Rockton Road, Roscoe, IL 61073 USA • 1-800-962-8979 • www.pbclinear.com
