Review on 🪑 GBL Casters Castors Furniture Workbench: Enhanced Mobility and Versatility for Your Workspace by Bryan Finken

Bearing, bushing and pin shown. Well, there are no wheel bearings or bushings, just a bolt that goes through a drilled hole in the center of the wheel. Two wheel casters do not work like two wheel casters to change direction because the studs that run through the center of both wheels rub against each other causing friction and preventing them from turning independently.
