Important Considerations For Designers At Reviewing Bearing Systems with Linear

By Nigel Dawson

The majority of electro-mechanical axis utilise extruded aluminium profile in a range of sizes with a single guide rail and bearing arrangement driven by an electric motor through a belt or ball screw arrangement. There are physical limitations to the forces such a system can accurately and reliably guide. This paper explores some alternative design arrangements to cope with higher load applications and identifies design considerations observed during the development of a Festo high load, twin rail system.
