5.1 inch replacement caster wheels

These 5.1 inch black wheels are sold as a two-pack for repairing shopping trolleys, station hand pushcarts, travelling luggage carts and bike carts. Each wheel is made from rubber foaming and plastic and weighs 56g. They are intended for light-duty transport where a quick, tool-free swap is needed.

Sustained load capacity of 3kg per wheel

The manufacturer rates each wheel at 3kg or 6.6lb, which is the figure to rely on for continuous use rather than the higher 5kg peak value. Rubber foaming material absorbs vibration on smooth floors but will compress more under constant heavy loads. Plan the total cart weight so that no single wheel exceeds this sustained limit.

Check mounting hole depth

The wheel requires an 8mm mounting hole that is 33mm deep with a grooved bearing to engage the built-in buckle. Your axle shaft must be at least 32mm long at each end and 7-8mm in diameter. If the existing caster housing lacks the matching groove or the shaft is shorter, the wheel will loosen and fall off.

Questions about this item

Will the 5.1 inch rubber-foam wheels stay quiet and roll smoothly after hours of use on hard floors?

The rubber-foaming tread on each 5.1 inch wheel is designed to absorb vibration and reduce rolling noise, while the plastic hub keeps weight to 56 g for low rolling resistance during extended use.

My cart axle is 8 mm with a groove — will the 33 mm deep mounting hole and built-in buckle lock on securely?

Yes, the 8 mm mounting hole is 33 mm deep and includes an internal buckle that engages the groove on your axle; the shaft must be at least 32 mm long at each end and 7–8 mm in diameter for a firm fit.

Can I mix these 5 kg-capacity wheels with the original 3 kg plastic wheels still on my trolley?

Each new wheel supports 5 kg, while the originals are rated at 3 kg; the higher-capacity wheels will carry more load, so the older wheels may become the limiting factor if weight is unevenly distributed.
