RoundRail linear guides are the non-driven building blocks for linear slide tables. They offer flexibility to fit specific envelopes by allowing customized separations between shafts and/or bearings on shafts to produce higher moment capacity. When combined with ball screw assemblies, they become a driven slide table. 

Why Thomson Linear Guide Systems?

For optimal self-alignment of bearing components with minimal stress, Thomson linear guide rail systems deliver ultra-smooth travel when mounted to wider-tolerance, prepared surfaces. Our linear rail systems are available in a wide range of sizes, bearing types and mounting configurations to best accommodate your motion control designs and applications. 

Customization Options

Despite our multitude of linear guide options (end and continuous support, FluoroNyliner®, side-mounted, dual and twin shaft, etc.), sometimes your design projects require a solution that falls outside of our standard offering. In these instances, Thomson application engineers are happy to work with you to customize a roundrail linear guide system that meets your exact specifications.
