Backlash is an inherent property of lead screw assemblies due to the sliding motion between the screw and the nut. For some applications, a certain amount of backlash, or “play,” can be tolerated, but applications such as positioning, dispensing, or assembly often require a level of precision and repeatability that can’t be achieved if backlash […]

Linear motion systems: Only as strong as weakest link
Demands placed on linear systems in today’s automation are greater than ever — and continue to increase. Here we review five links in the chain of design elements so critical to precision operation. By Mark Huebner • Mechatronics global product manager | PBC Linear Kevin Bischel • Principal engineer | PBC Linear A linear motion […]
What is a follower nut, and what role does it play in lead screw operation?
Although the idea of a “follower nut” may seem to indicate that the nut serves a passive role in lead screw operation, it actually plays an important part in monitoring the condition and life of the screw assembly. The wear characteristics of a lead screw nut make the expected service life of the assembly difficult […]
New Thomson video shows customer’s use of electric actuator synchronization option
Thomson Industries, Inc., a leading manufacturer of linear motion control solutions, has released a video showing how the synchronization feature available with its Electrak HD electromechanical linear actuators helped Spika Design and Manufacturing address a growing customer demand.
