## Description

100pcs 3/32" 2.381mm Si3N4 Silicon Nitride Ceramic Balls G5.

Review: Great for rebuild of Shimano PD-A600 - I have 2 sets of Shimano PD-A600 road/touring pedals that I use for gravel racing and touring/road. These get a lot of miles and I purge and refresh the grease in them every month or so. They started clicking. It was loud and annoying as %#$!. People started to shun me - who could blame them - and eventually even dogs wouldn't bark at me. 3/32 is the ball bearing size, and if you are going to go - go ape - upgrade to ceramic bearings and save .00001 grams per pedal. Disassembled and rebuilt with these ceramic bearings, fresh marine grease, and now have silent, click-free pedaling. Right after replacing I did a 205 mile ride with nothing but the hiss of tires on the road - awesome. ****Added bonus - ceramic is harder than steel, so the new bearings will actually polish and smooth any micro nicks or pits in the bearing races from the skanky old bearings. 4 pedals x 24 bearings each leaves 4 left on the workbench, so the count was accurate. Really can't go wrong here.
Review: Perfect for linear rails - Bought these to clean up some old and sad linear rails that were missing some balls. Unfortunately, I discovered that MGN12 blocks take about 68 balls a piece, so I was a little short on the four that I needed to fill only ordering 200. That said, I did get full bags, so they seem to be doing better with the packing. I'll be buying the other 100 that I need to fill the last block.

### ⭐⭐⭐⭐⭐ Perfect for linear rails
*by W***M on February 10, 2021*

Bought these to clean up some old and sad linear rails that were missing some balls.

### ⭐⭐⭐⭐ Most of them were very close to spec, some a bit oversized. Received 100ct, as ordered.
*by A***. on January 8, 2023*

Measured 30% of the bearings I received (counted one by one, 100 in the package, bad reviews probably lost some). 29 out of those 30 measured in at a slightly undersized 2.379. This is within my calipers spec (+-0.003mm). The one that was not within this spec was way oversized, measuring 2.39. These will likely be a good purchase for most, if you are willing to clear each ball manually to pull out the out of spec ones. I WOULD NOT get these with the ENOMAKER rails that amazon suggests, as those rails have severely undersized bearings due to the coating on the rail.
