Frequently asked questions
Is it a driven wheel?
No, it is a passive caster. It supports the chassis and turns freely, so the drive wheels or motors must provide propulsion.
How do I mount it?
Fasten the caster to the underside of the chassis through its mounting plate. Check that the hole spacing matches your chassis and that the ball clears the surface.
