Hi, I'm working on a project with a unique mechanism and I need some input regarding the bearing selection and mechanical setup. First of all, does anyone know where I can learn more about bearings in general? I'm having trouble finding info about them. Second, has anyone here ever worked with timing belt profiles? The profile is a shaft sleeve that allows a shaft to be attached perpendicular to the belt on multiple sections of the belt. I'm concerned about having alignment issues because the timing belt may twist slightly when the bearing is being rotated.
