Precision Lead Screw

The Lead Screw line from PBC Linear was designed to work perfectly with the Constant Force Anti-Backlash nut. Through years of testing and process improvements, PBC Linear 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

Innovative Anti-Backlash Nut

The patent pending Constant Force Lead Screw line from PBC Linear uses a method 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

World Class Motors

PBC Linear’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.
