Constant force nut outputs uniform pressure to the nut at all stages of the motion profile

Constant Force Lead Screw line,  PBC Linear, nuts, and hybrid linear actuators

The new Patent pending Constant Force Lead Screw line from PBC Linear uses a constant force spring to apply uniform pressure to the nut at all stages of the motion profile. Compare this to a traditional anti-backlash nut which has a variable twisting force that can result in a loss of pressure on the nut.

•Superior Performance: 2-4x less backlash over the life of the device, as validated by leading lab automation customer testing
•Self-lubricating: All nut styles offered are self-lubricating for the life of the nut

The new Lead Screw line from PBC Linear was designed to work perfectly with the new Constant Force Anti-Backlash nut. Through years of testing and process improvements, PBC is proud to offer the most accurate standard lead accuracy on the market.
•CNC Roll Threading: Allow for standard accuracies of .003”/ft. (2-3 times better than the competition). Precision lead accuracy of .001”/ft is available upon request.
•Smooth is better: Proprietary process has resulted in less pitting and flanking, which results in longer life. Internal and customer testing have the screw/nut combination lasting at 6,000+ miles in continuous duty. (application dependent)
•300 Series Stainless Steel
•PTFE Coating available

PBC’s partnership with Moons Industries has allowed for a combination of extremely reliable stepper motors and great lead screw technology. The result is the Introduction of a full line of Lead Screw Motors.
•Sizes NEMA 8 – NEMA 23
•Laser Welded: screw & motor providing the most accurate alignment possible from the factory, while saving money & allowing for smaller size.
