100 3/32" Inch Chrome Steel Bearing Balls G25

These bearings turned a some pretty sloppy linear rails into pretty tight and useful linear rails on my Ender3v2. Well worth the cost and effort.

These bearing balls are actually 3/32". I measured most of them by hand and they were accurate down to .01mm, so I'm happy. I used them to replace the cheap bearings in my linear rails and they work great for the price.I just had a set from another seller for being .20mm larger than 3/32". Seems like a lot of sellers aren't very truthful with the quality of their products. Luckily, these are exactly as advertised.

Fit perfectly Shimano Saint 2014 model pedals. Cannot find this size in any store or bike shop. Good quality, i use them for a year and the pedals feels the same, no play or sign of wear.

The media could not be loaded. I took the time to disassemble the rails and the carriage, and clean everything completely.Out of the box 2 of the carriages were very tight and would hang sometimes. one was a bit looser but would also hang occasionally. So after disassembly and cleaning with Isopropyl alcohol.With these rails i ordered some spare bearings (amazon.com/dp/B015RKOZ7G) in-case they were needed and they were certainly useful. I however didn't fully replace all of the bearings in the end because that made the carriage too loose. What i ended up doing was replacing half of the bearings on just one side and that made these tight rails butter smooth.I also did end up swapping some of the carriages to different rails to improve things. In the end all of my rails are now super smooth and great!

Love this!! It's the perfect size for what I need it for and it came with 16 extra ball bearing, if I need more in the future I'm definitely ordering them again. 😊

I have several precision calipers and measuring devices that I used to test sample bearings and they all measured as indicated. I was +/- .001mm with random testing and that is at the limits of my test measuring gear plus more than good enough for my CNC and 3DP linear rail carriages. The price was fair, delivery was prompt and the bearings were as described.

I recently bought an inexpensive set of linear rails. Based on the various YouTube evaluations of the these Chinese manufactured rails, the biggest problem (besides the nasty grease they pack them with) is the inconsistent ball bearing size and quality. These ball bearings are an inexpensive upgrade to your linear rails. Clean out the block, pull out the old ball bearings and reinstall with these bearings and a small amount of Super Lube 92003. A reasonable cost rail upgrade!Like this review? Please click "helpful" below
