Casters on the 4 x 4-1/2 plate pattern suit warehouse carts on epoxy and smooth concrete. Typical builds show wheel diameters 4, 5, 6, 8 in, polyurethane treads, and capacities 750 to 1,000 lb. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level.

Blue Solid Polyurethane Wheel Casters: buying guide

Blue solid polyurethane wheels are a one-piece urethane wheel in a distinctive blue compound. Solid through — no separate core, no tread to delaminate. The blue color is a visual marker: it signals a non-marking, premium-compound wheel to anyone auditing the equipment.
