4"X1.5" Heavy Duty Casters-High Temperature Oven Rack Casters, Industrial casters-Set of 4 with Loading Capacity: 2800LB (4 Swivel)

Super affordable in the world of industrial high temp casters. We use these on our (3) carts for our powder coating oven.

I bought 4 High Temperature caster to replace my restaurant moving counter. My wheels have to be resisted the high temp up to 200F. These wheel surface clean and bright, material is hard and heavy, the 2 swivel steel rig works flexible, and heavy duty. Great value. Hope it can be lasted for several years. Recommended!

Husband does powdercoating and needed to make his own racks for the oven. These are working well for him. So far so good. Will definitely be buying more

I love the quality!

these are crap wheels. I would like to get my money back, but the guys throw them away. so we ordered the other one's that are great. x001uqesrz.. part number that was great is z20p2431ngd these are the good ones.The company said to get my refund from amazon.thank youopal gallagher

The media could not be loaded. TL;DR; Typical double ball bearing casters with solid polymer ball bearing wheels. I’m unable to test the high temperature feature. Minor locking bar defect easily corrected.I’m using these for shop and barn purposes in general and these are destined for a welding table on rough surfaces in a barn.If you have used this type of caster before then I’d say they are typical with one other additional feature. I generally lubricate my casters on installation with 30 weight engine oil or 3 in 1 oil whatever I have at hand. The lower race on these casters has a new to me feature of a lubrication hole to get into the inner portion of the lower race. See photo. It’s just a hole in the race but I rather appreciate that access.This is a bench review not in use but I have been using a couple of dozen of these type of casters and this particular one is top quartile in terms of look and feel. I’d be disinclined to use these in high temperature environments or high continuous weight environments as I prefer solid cast iron or cast aluminum wheels in that application. OTOH I have never had a polymer wheel fail on a good quality caster like this so that may just be my prejudice and polymer wheels certainly roll more pleasantly.The wheel is accurately pictured and appears to be a single piece of moulded polyurethane over a ball bearing. The bearing can’t be observed directly but has a steel sleeve the wheel axle bolt passes through and it rolls to easily to be anything else. I did not try to remove the steel sleeve but there is a gap between it an the polymer moulding to introduce oil. See video.There was one defect on this caster likely introduced in the shipping process and easily remedied. The locking bar was bent slightly more than 90 degrees and very slightly interfered with the rolling of the wheel. I just inserted a screwdriver between the bar and the wheel to bend it back slightly.4.5 stars, nice execution on a caster great description and pictures very minor defect.

These heavy duty casters swivel nicely! The wheels lock solid via a downward lever-cam action that engages with an indent at the very end - a nice feature that ensures you have it locked all the way (note this locks only the wheel, not the swivel). I think these would serve large utility carts and mobile tables well, especially if used on smooth concrete-like surfaces. But with the 4 inch diameter, this would be capable of rolling over some small bumps and cracks. The wheel is a really hard epoxy plastic-like material, hard enough to withstand great pressure, and heat. Because of this hardness, you might want to avoid using it on softer surfaces, like a wood floor, or painted floor, or anything more delicate. But, these wheels should hold up to some hard use. I like that it's double ball bearings, and a grease fitting installed for the swivel, should be able to service and maintain these for decades! A good choice for the obvious industrial kitchen cart, but also for use at a glass fabrication shop, or metal forge facility. Of course these don't have to be used just in high heat application, they are also applicable general rolling tables, utility carts, moving dollies, mobile bases, etc!

I got these casters to replace the wheels on my welding cart that carries my welder, welding supplies and large very heavy welding gas canister. These are very well built, very heavy duty caster wheels. While they are specifically intended for baking carts that will be exposed to very high oven temperatures I won’t be exposing them to such harsh duty in my application. The wheel material is very hard and rolls well on soft surfaces such as wood, carpet, linoleum, etc. On hard surfaces such as concrete they provide a bit of a rougher ride, but will certainly hold up better than soft polyurethane wheels. As well, if your cart payload is heavy these wheels will not develop flat spots as so many of the softer wheels tend to do when sitting stationary over time.
