Greeting to all,
I have been concerned about shaft deflection and support. Typical solution is to go with a larger dia. shaft and/or shaft support. This would require a rail mount system of some type. Thinking outside of the box, the support is only needed when deflection is present, and then only where the load is at that particular point in time and distance.

So, why not make the shaft support travel with the load. I attached a file of concept that might resolve some deflection issues. The idea is that the load is carried by the shaft and sleeve bearing, then under downward force the load is transfered to a ball bearing running directly under the shaft and the sleeve bearing. This should prevent shaft deflection ???

Please let me know your thoughts.

Thanks
