4Pcs 2"Chrome Steel Bearing Balls (51mm)

I'm using these as solid Baoding balls. The bearings are well made with no imperfections.

I bought these 1.5" (38mm) steel balls to clear clogs in my shop vac hose. Every week I vacuum a chicken coop with wood shavings, and waste clumps sometimes block the hose. These balls are the perfect size and heavy enough to roll through the hose and break up the clog. Even if you don’t have chickens, you might still enjoy them. They’re solid, satisfying to hold, and could be useful for many projects. The finish is polished steel (not chrome), so they may rust over time, but they can be kept in good shape with a little care.

Im not sure of why anyone else would get this obnoxiously sized ball. It sits there waiting to fall or kids to pick it up and give you a mild heart attack holding it over a sibling's head. I got it to use as an example of mass (more specifically the weight of my 3d printer bed). It is just as awesome as it looks, only bigger. It is the literal diameter as stated in the description. It is slightly out of round if you use a micrometer or if you put it in the biggest ball bearing ever. Tldr if you are looking for this ball it is as cool as it gets, if you are late night amazon scrolling... Just kidding I don't tell people what to do.

Great value for the money, the smoothness, size, weight, and bearing quality are excellent. I got these to use for hand exercises, and they are working great. They're exactly like the solid baoding chinese exercise balls, and this package has enough to use with both hands at the same time. They are even large enough to do the burn through science trick smacking them together with a piece of paper between them.

Great for use of internal material for whip making hobby

One star off because of the way they were packed. They were packed so they rubbed against each other during the trip and we're slightly scuffed because of it. They put both of them in one bubble bag which makes no sense because they bump into each other inside the bag. I put some metal polish on them and stuck them in a towel like a hammock and polished them like you do with a bowling ball. Fortunately, the scuffs were buffed out. I figured these would work great for a light workout everyday for the shoulders and arms, and they do. These are much more convenient than swinging dumbbells around, and 4 pounds or so, each, is enough for me at 64. It gives you a harder workout than you would initially think. They're great for lateral raises and rotational exercises. You can do anything with 3" steel balls that you can do with dumbbells, but you don't have to deal with the awkward bulk of a dumbbell. Hello it is right there in the palm of your hand. Of course, you're not going to build much mass with 4 lb, but it's good for toning. Its certainly better than sitting on the couch and becoming a potato, or more of a potato than you already are. My wife can use my balls to get a bit of a workout too if she wants. Lol

These a solid. I have not put them on a micrometer as I don’t need them that precise and won’t be measuring them. So if you’re in need of solid bearing balls this size, these are it. They’re perfect for my needs. Better than perfect. Just by my hardness tests, don't expect to drill into them. They are HARD steel.

They make great monkey Fists

No hay mucho que decir. Son exactamente como se describen

Excelente producto lo estoy usando para un proyecto

Que no miden 12,7mm, como dicen, mide 13, por lo cual no sirven para pistola traumática de aire comprimido, las conservé para mis “resorteras”, una desilusión.

Gracias es un producto bueno.

Es mentira que no se oxidan . Las use en proyecto de carpintería y se oxidaron unos días después de introducirlas en la artesanía , por ende me arruinó el proyecto u me hizo perder mucho dinero y tiempo
