Driving a bearing out needs a firm surface with a gap underneath for the bearing to drop into. This stand is a hard maple block with a non-marring rubber top and a figure 8 through hole. It supports parts from 608 caster bearings with an 8 mm bore up to R8 rear wheel bearings with a 1/2 inch bore. It arrives needing four screws and a Phillips screwdriver, and can be clamped down.
Suits anyone who uses a punch, puller or press on wheelchair casters, rear wheels or fork assemblies. It is a support only, so a punch or puller is still needed to move the bearing.
