Hi! my project is a small conveyor assembly where the rollers need to be swapped out fairly often, depending on the material we’re running. I’m considering using an M14 threaded connection between the aluminum roller hub and the steel shaft, so the hub would screw onto the shaft up against a shoulder. To secure it, my idea was to use a standard steel locknut tightened against the hub. On paper, this looks compact and easy to service, but I haven’t come across many examples of threaded hub-to-shaft connections in roller assemblies. My concern is whether vibration and load cycles will cause the hub to back off over time, even with the locknut. Has anyone here tried a similar approach, and is there a good reason why this isn’t common practice? thx
