4" x 1-1/4" Solid Polyurethane Wheel w/ Plain Bore - 31UD40-24

About This Wheel - 31UD40-24

Choose this 4-inch solid polyurethane wheel with the plain bore for a light cart that must keep rolling in a wet or dirty spot with the fewest parts to fail, the one-piece wheel with no tread to peel and no bearing to seize.

Stepping up to 4 inches over the smaller plain-bore wheel lets a light cart clear a low threshold or a floor seam without adding a bearing to maintain. The wheel is solid Blue polyurethane through and through, so there is no bond line for shock or chemicals to attack, and the plain bore rides straight on the axle with nothing to wash out or rust. The polyurethane stays non-marking and tough in the cold to -50°F. The 1-1/4 inch tread carries a light load.

Ideal applications

• Light cart clearing a low sill in a wet or dirty area
• Simple low-speed rig with no bearing to service
• Cold-spot cart to -50°F where a bonded tread debonds

Skip the plain bore if the cart cycles fast or carries more; a solid polyurethane wheel with a roller bearing rolls easier under heavier use.

Pairs with: a matching 4-inch caster fork and axle to build a swivel or rigid caster, from the Caster Hardware collection.

Wrong fit? Need a bearing, or more load? See the 5-inch roller solid polyurethane 41UE52-24 and the solid polyurethane wheel collection.
