About this category

What you need to know about high-temperature casters.

High-temperature casters and wheels are rated for sustained heat exposure where polyurethane and rubber would soften or melt. Three compounds dominate this category: phenolic resin (flat-tread, most common bakery oven rack spec), silicone-on-aluminum (highest sustained-heat rating, autoclave and sterilization spec), and high-temp epoxy (mid-range, dishwasher and proofing-rack spec).

P&H high-temp wheels on SCW include the WL40 phenolic family (WL4052BZ, WL4052BN, WL4062BZ, WL4082BN — sized 5-inch to 8-inch), the WH2040BG3C 4-inch phenolic bakery wheel, the W12043NL/NU epoxy wheels for light-to-heavy bakery applications, and the W22043N0B silicone-on-aluminum wheel for the highest-heat in-oven positions. The T30C141CLDTB stainless caster is brake-equipped for sanitation-spec applications adjacent to high-heat environments.

Phenolic doesn't roll as quietly as polyurethane and isn't appropriate for customer-facing retail floor applications, but for back-of-house heat-exposure environments it's the only spec that holds up.

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.
