Lead Screws & Supernuts®
Offering smooth, precise, cost effective positioning, our lead screws and Supernuts® are the right solution for your application. The Supernut® product line consists of both standard and patented anti-backlash nut designs that offer the highest level of repeatability. Thomson BSA precision lead screws are an excellent economical solution for your linear motion requirements. Our precision rolling process ensures accurate positioning to 0.003 in/ft and our PTFE coating process produces assemblies that have less drag torque and last longer.
Supernuts®
Thomson BSA provides a large array of standard plastic nut assemblies in anti-backlash or standard Supernut® designs. All of our standard plastic nut assemblies use an internally lubricated Acetal - providing excellent lubricity and wear resistance with or without additional lubrication. Learn More >
Bronze Nuts
Bronze Nuts can carry significantly higher load than plastic nuts. Thomson BSA uses SAE 660 bearing bronze for the best combination of load capacity and lubricity. For optimum performance, always use our TriGEL-600SM lubricant to reduce friction and keep your system running its best.Learn More >
