About this category

What you need to know about bakery & oven rack casters.

Bakery rack casters take more punishment than almost any other cart caster in a retail environment. Pan racks roll loaded into and out of ovens, hit oven gaskets, then come back to room temperature, then heat up again on the next bake. Cheap polyurethane wheels soften and flat-spot. Standard rubber wheels char.

Per the P&H Casters Retail Guide, the bakery casters supplied to factory bakery rack OEMs are the Z20P254CLDE, Z42P352CLPL, Z40P382CLPL, and the high-temperature WL4052BZ phenolic and W22043N0B silicone wheels for the inside-oven rack positions. The 5-inch CLDE family is the standard pan-storage and proofing-rack wheel; the 8-inch CLPL is on the largest commissary racks; and the phenolic and silicone wheels are reserved for the wheels that actually enter the oven.

If you don't know which spec your rack uses, send a photo of the wheel and the rack frame to our team — most US bakery racks use one of the four part numbers above.

Which shopping cart wheel do I need?

Most US grocery carts use a 5-inch wheel with a 5/16-inch axle in a polyurethane or rubber tread. If you operate a Walmart, Target, Publix, or Whole Foods cart fleet, the OEM cross-reference is on the matching retailer page. If you do not know your cart manufacturer, measure the wheel diameter across the tread, measure the axle hole, and pick the matching universal P&H wheel. Polyurethane lasts longer and handles flat-spotting better than rubber, but rubber is quieter on hard floors. For 24/7 operations or heavy carts, choose a wheel rated 250 lb capacity or higher per wheel.

If you can send a photo of the existing wheel and a measurement across the tread, our fitment team will confirm the exact match within minutes during business hours. There is no upcharge for fitment review.

Frequently asked

Cart wheel buyer questions.

Top questions from store-ops teams and refurbishers.

How do I measure my cart wheel?

Lay a ruler across the face of the wheel from one outside edge to the other, through the center of the axle. That is the wheel diameter. Then measure the axle hole through the hub center: most US carts are 5/16 inch, but some specialty carts use 1/2 inch. Tread width is the thickness from inside face to outside face. Full measuring guide.

What is the difference between polyurethane, rubber, and TPR wheels?

Polyurethane lasts longer, handles higher loads, and resists flat spots from parked carts. Rubber is quieter on hard floors and slightly cheaper. TPR (thermoplastic rubber) sits in between. For high-traffic stores, polyurethane is almost always the better long-term cost. Material comparison.

Can I order in bulk for my whole fleet?

Yes. Volume tier pricing applies automatically at 50, 200, and 500+ wheels. Multi-store fleets get dedicated reps, NET-30, EDI, and custom packaging. Fleet program details.
