3" (76.2mm) Ball Bearing Solid Steel Balls Precision Balls

Item is good quality and worked great for my application.

Perfect, just what I need to keep the concrete guys in line.

This thing is a beast. Super heavy and quite the desk toy. Do not drop this on anything you care about.

I know this probably isn't a conventional use for this, but these are absolutely fantastic for weighing down spools used in 3D printing (more specifically, in my Bambu Lab's AMS). For this application, I would recommend 1.5".I have not had any issues with the finish or rusting. These came smooth and have a polished appearance. I feel like these will last a long time (for how I'm using them anyway).

I randomly saw these while looking for 11mm Bearings to use as Pachinko balls in for my collection of authentic vintage Pachinko Machines from a Yakuza run Pachinko Parlour in Tokyo. Once I saw these I ended up with a pair of 1” 1.25” 1.5”1.75” 2” 2.5” 3” 4” 5” to display. Man these are really heavy and I keep them displayed with the 2” and 3” in my coffee table. Everyone who come over unfortunately be come absolutely mesmerised by the size of my Shiny Steel Balls, they can’t resist them. It quickly progresses to people touching my steel balls and then nonstop fondling my Steel Balls for hours. They don’t want to put them down. One person actually tried to walk off with them attempting to take them home. I have to watch my steel balls like a hawk. The worse part is people always leaving them smeared with finger prints. I might end up locking them behind ballistic glass for safety! You should get your own pair of big shiny steel balls a pair is better then one!!! Your life will change forever!!! Hands up n Hands down buy your own set ASAP!!! You can’t go wrong with multiple sizes of Big Shiny Steel Balls!!! Do It Now!!

Doesn't come with jar as shown. Comes in plastic bag. Otherwise they're fine.

I like holding onto one in each hand and moving my arms around in any old direction.the balance of which seams to make my my fore arms feel club-like in the way i can imagine how a bowling ball would feel if picked up from the top,but the top actually being the bearing snugly enscounced within my grip.i keep thinking of the overall feel in comparison to the odd shaped weights in a crankshaft.Odd but true.Buy the set of four,you will be so thrilled by the feel of the weight you will probably want to give a pair as a gift.

I use these in my Bambu AMS - just put one in a spool and it keeps traction on the rollers.
