Thomson BSA® precision lead screws are an excellent economical solution for your linear motion requirements. For more than 25 years, Thomson BSA has designed and manufactured the highest quality lead screw assemblies in the industry. Our precision rolling machines ensure accurate positioning to 0.003 in/ft and our PTFE coating process produces assemblies that have less drag torque and last longer.
Jeff Johnson, Thomson Screw Product Engineer, says ball screws and lead screws can sometimes be used in the same applications. Typically, ball screws are used in industry applications that need a lot of load or life while lead screws are used in smaller, lighter duty applications. Lead screws however are highly customizable with the ability to interchange leads, sizes, nut configurations quickly. Cost is usually not the primary consideration when selecting a screw technology. Watch this video to learn the differences.
