Kayak cart Wheels (100% Corrosion proof)

Granted I don't get out much so this may be general knowledge, but I've never seen these wheels anywhere except on my own home made cart.  They're the only absolutely corrosion proof wheels I have ever found, wheel and bearings are 100% plastic and so far work great for me, (although I haven't got sand into the bearings yet). A 1" OD aluminum tube from Ace made a perfect light weight axle.

I see the link doesn't work, so go to seitech.com, choose parts and accessories, and catagory - wheels,  You'll get a list of wheels and parts, I used the B wheels, last on the list.

Is this the one?

Think it has been used by Travis and didn't perform very well in the sand.

thanks for the feedback,  looks like the picture also has tracks from some wheeleez wheels, any experience on how those plastic/SS bearings hold up with salt and or sand? 

Actually no bearings seem to be the way to go. The WheelEz don't have any and have been working like a charm. Those WheelEz people really hit a home run with that cart. It'll be a hard one to beat.

Looks similar to the wheels used on my first Roleez kayak cart.  I can vouch for the suckiness of those wheels when it comes to sand...it's easier to drop the wheels and pull the yak like a sled than it is to pull those wheels through soft sand.  They work great on trails or concrete though. 

Thankfully, I have my new Wheeleez cart for use on the beach!
