I'm not that familiar with any of these components so this question can sound a bit basic.
I'm starting some mechanical project which involve a timing belt, basic pulleys and a small motor with a gearbox. I'm building a small actioner which push a element along a aisle, the plan is to build many of this and be able to maintain in the future.
I want to find easy to replace parts without need to be depending of a single providers/manufacturers or need to custom made it to avoid need to re-design when need more parts in the future. Are there some standards around, formats, measures, sizes of this kind of parts?
This are some examples of what I need:
