Now we are looking for a company to supply us with the complete set of wheels and axle that is used in large plastic garbage bins that are typically used in hotels and commercial areas. The wheel diameter is 8", rubber tread molded-on a black plastic hub/rim, and has a locking mechanism that allows the wheel to be fitted (snap in)onto the axle without any tool. The steel axle is plated steel shafting, about 1" in diameter or less. When assembled, wheel to wheel distance is about 14". The wheel has a long protrusion that acts as a spacer to prevent the wheel from touching the side of the garbage bin.
