As you can see in the pic I swapped-out one of the "stock" wheels on my gate carrier for this grooved caster.TIPS:1 - Make sure you know the axle bore you require before ordering. (If it's not the default you can request the size you need.)2 - Also make sure your axle can accommodate the caster's width.3 - I actually ordered a 5" diameter caster even though the carrier's opposite wheel is 6" in diameter (see pic). The reason for this is that the caster rides atop an inverted V-track which elevates the axle. So the caster's axle is raised about 1/2" to basically match the level of the 6" wheel opposite it. Cool, huh? ### ⭐⭐⭐⭐⭐ Nice Wheel *by S***W on Reviewed in the United States on November 24, 2019* This wheel replaced an aluminum and rubber wheel where the heat in Florida released the glue between the rubber and the aluminum in the shop. This wheel fits well in replacing that wheel and will hopefully withstand the heat better, since it is of a different compound. ### ⭐⭐⭐⭐ Used as a replacement for kids hovercart *by B***O on Reviewed in the United States on June 30, 2020* Very nice wheel. We used a 6x2 rubber over cast iron with ball bearings to replace the garbage pneumatic tire that came on my son's hovercart. He says it rides great and it looks really cool too, like a mag wheel. The rubber is not too hard at all, I think it's a 70 Shore A hardness which seems perfect for this application. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/252214880-4-x-2-polyurethane-on-polyolefin-wheel-only-with-roller](https://www.desertcart.nz/products/252214880-4-x-2-polyurethane-on-polyolefin-wheel-only-with-roller) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-06-19*
