Performance Benefits of Lead Screws and Nuts

CNC Roll Threading: Offers standard accuracies up to 0.003”/ft., with precision lead accuracy down to 0.001”/ft. on request, ensuring superior precision over competitors.
Durability: Custom coating process results in less pitting and flanking, extending the life expectancy of the screw/nut combination to 6,000 miles in continuous duty, depending on the application.
Material Quality: Constructed from 300 Series Stainless Steel for strength and durability, with optional PTFE coating available to further reduce friction and enhance efficiency.
Self-lubricating Designs: All nut styles are self-lubricating for the entirety of their lifespan, minimizing maintenance requirements.
Anti-Backlash Nuts: The Constant Force Anti-Backlash options deliver 2-4x less backlash over the device’s lifetime, confirmed by leading lab automation customer testing.
Temperature Resilience: Designed to excel in temperatures ranging from -30°C to 120°C (-22°F to 248°F), accommodating various environmental conditions.
Customization: Available machined journals to suit specific application requirements, alongside the availability of standard and custom ball screw designs.
Versatility: The collection includes various nut shapes (triangle, round, rectangle) and special features like constant force anti-backlash, catering to diverse operational needs and installation scenarios.
