Forklift PU Caster Wheel – 80x70x47mm

Forklift PU Caster Wheel — 80×70×47mm Polyurethane Hard Tread Replacement Caster Wheel for Forklift & Pallet Trucks

This forklift PU caster wheel measures 80×70×47mm with a hard polyurethane tread, designed as a direct replacement caster wheel for forklift steering axles and pallet truck caster assemblies in warehouse, logistics, and industrial environments. The three dimensions define the complete wheel specification: 80mm outer diameter determines the overall wheel height and rolling circumference, 70mm tread width provides the load-bearing contact surface that distributes the weight of the forklift across the wheel-to-floor interface, and 47mm bearing bore inner diameter must match the axle shaft or bearing outer race on the caster fork assembly. Using a wheel with an incorrect bore size — too large will wobble and cause uneven wear, too small will not fit over the axle — is a common installation error that leads to rapid wheel failure and potential caster fork damage. The hard polyurethane tread compound provides the optimal balance of durability for continuous industrial use, non-marking performance for sealed concrete and epoxy warehouse floors, and low rolling resistance for manual pallet truck applications where every kilogram of push force matters for operator ergonomics. Unlike pneumatic rubber tires, PU caster wheels never go flat, require zero air pressure maintenance, and maintain consistent rolling characteristics regardless of ambient temperature — critical for cold storage and freezer warehouse operations where rubber hardens and pneumatic tire pressure drops with temperature. 5kg gross weight with 30×30×30cm compact packaging. OEM support available for custom sizes and hardness specifications.

Installing the 80×70×47mm PU caster wheel requires removing the axle bolt or retaining clip from the caster fork, sliding the old wheel off the axle, and installing the replacement. Before installation, inspect the caster fork for cracks, bending, or corrosion — a damaged fork will cause the new wheel to wear unevenly and may fail under load. The wheel bearings — typically sealed ball bearings pressed into the 47mm bore — should spin freely and silently. If the old wheel seized because of bearing failure, the axle shaft may have been scored or worn by the frozen bearing inner race rotating on the shaft — inspect and replace the axle if scored. After installation, the wheel must spin freely without side-to-side wobble. For pallet trucks with tandem caster assemblies where two wheels share a single fork, both wheels should be replaced as a pair to ensure even height and load distribution.
