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. Festo has published a new whitepaper “Key considerations for designers looking at bearing systems with linear axes”.
The white paper can be downloaded for free and aims to help designers understand 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.
“Since 2008, Festo have manufactured highly successful electro-mechanical axes,” said Nigel Dawson, product manager at Festo. “We identified the opportunity to offer machine builders a single combined axis solution with a wider profile with multiple guide rails to cater for high load applications. Whilst this seemed a simple task, the reality of developing such a solution proved more challenging than first considered and highlighted some useful insights for design engineers, which are shared within this whitepaper.”
