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.
Why are lead screws such a popular choice for precision linear applications? Learn not only their long list of benefits but how you can put these components to work for your design projects and applications.
Presenter: Saurabh Khetan, Product Line Manager - Lead Screws, Thomson
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.
For proper performance of your XC lead nut, installation steps for its five components must be followed closely.
Which motor is right for your lead screw application? A properly integrated lead screw and motor can cut costs, boost performance, simplify maintenance and provide greater prototyping flexibility. Three of the most common approaches include implementing an external shaft coupling; permanently or semi-permanently fusing the lead screw and the motor shaft together; and using detachable connections. This article covers the key considerations when comparing these options.
Learn MoreWith careful attention to selection and application, lead screws can deliver efficiency that comes close to ball screws on many applications, high levels of load capacity and very good positioning accuracy. Lead screws also offer many other advantages such as more flexible configuration and form factor, the ability to operate without lubricant, quieter operation, clean materials and lower cost. This article examines how to determine whether a particular application is a good fit for lead screws, and how to select the right lead screw for the application.
