Precision miniature lead screws for the smallest application designs

Thomson Industries has introduced a line of miniature lead screws and nuts. This new offering extends the Thomson lead screw product line to include 2-, 3- and 4-millimetre diameters.

“OEMs are increasingly demanding components for smaller assemblies, and we are pleased to announce that Thomson high-quality lead screws and nuts are now available in diameters smaller than six millimetres. This provides our customers with additional flexibility to design more compact systems and is part of the ongoing expansion of our miniature offerings,” said Saurabh Khetan, Thomson product line manager for lead screws.

The new Thomson miniature lead screw line is available with either standard or anti-backlash lead nuts to optimise positional accuracy, friction and repeatability. The anti-backlash lead nut design reduces friction between the nut and screw threads in order to optimise efficiency while still eliminating play between the lead screw and nut.

Customers can specify a variety of lead options and end machining capabilities for maximum flexibility in final assembly and precision at a miniature scale. As with all Thomson products, a wide variety of customisation options are available. For ease of mounting and integration, Thomson also offers oversized end machining options such as journals and even a brand new, integrated coupler design, which allows customers to easily mount the lead screw onto various shaft diameters without the need of an additional coupling component.

Thomson says the smaller screws are ideal for a wide range of applications but are especially valuable in emerging medical technologies and analytical equipment.
