Shopping Cart Wheel Matcher

Match a replacement wheel to a shopping cart, luggage trolley, or stock cart from its diameter, tread width, hub length, and axle bore, and flag the parts that must agree.

A cart wheel is a small part with several dimensions that have to agree at once. Enter the diameter, the tread width, the hub length, and the axle bore, and the calculator identifies the size class and lists the other dimensions that must match before a part can be ordered.

The measurements are the whole basis of the result, so the tool asks for caliper readings and says so when a dimension looks unusual. Load rating, tread compound, and colour are not part of the match, and they matter more for a stock cart than for a shop trolley.

Inputs

Measured dimensions

Range: 2–8 in

Measure across the tread face through the centre.

Range: 0.5–2 in

The width of the rolling surface, not the hub.

Range: 0.5–3 in

Distance across the hub from one axle face to the other. Too long binds the fork; too short lets the wheel rattle.

Range: 0.1–1 in

The hole through the centre of the wheel, measured with a caliper or drill bit.

Bearing and application

Result

Overall
This set of dimensions describes a common cart wheel and should be easy to source as a stock replacement.
Size class
Standard cart wheel class, which is where most shopping cart wheels sit.
Hub check
The hub length is proportionate to the tread width, which is the usual cart wheel proportion.
Bearing note
Plain bore: the bore is a clearance hole, so a slightly different bore can be bushed down, but the hub length must still match.
Cart note
Shopping carts are the lightest of the three, and a cart wheel is usually specified by dimension rather than by load rating.

What to check

  • Measure the hub length and the axle bore with calipers, not a ruler.
  • Check the tread width as well as the diameter; both are needed to identify the wheel.
  • Confirm the load rating separately for stock and material-handling carts.

A matching aid, not a parts database, so it does not name a part number and cannot confirm that a supplier stocks the combination. It depends entirely on the accuracy of the user's measurements, and it does not consider load rating, tread compound, or colour. The size classes are generic, and the boundaries reflect common practice rather than a standard.
