Thomson Industries, Inc., a leading manufacturer of linear motion control solutions, has introduced a family of compact linear systems that makes it easier for motion designers to implement complex applications in small spaces. Designers needing thrust and bearing support in a single, compact unit now have the flexibility to build such applications with versatile, time-tested components from Thomson.

To determine whether a machine screw jack or ball screw jack is the right fit for your application, Thomson and Motion engineers offer the following application parameters early in the design phase.

When designing for linear motion systems, the initial decision between round and square rail can significantly impact cost, performance and durability. Square rail, which is typically the more expensive option, has a higher load capacity and tighter accuracy. Round rail offers distinct cost and reliability advantages for certain applications, but maximizing those advantages depends on specifying the right bearing to minimize friction in each application. Designers must often choose between plain bearings, often called bushings, and ball bearings. And within each type, they will have more options that impact price, performance, maintainability and durability. Understanding these options early in the design cycle will optimize the performance and cost of the linear motion application.
