250 1mm Diameter Chrome Steel Bearing Balls G25

They worked as intended

Have an expensive watch bracelet tool set. The tool handle had a small ball bearing held in place by a small O-ring. The bearing applies slight "grip" pressure to the tool tip inserted into the handle so the tool tips can be switched out quickly but stay in place. My O-ring disintegrated from oxidation (old age) and the bearing was lost. My tool was virtually unusable. I used this bearing as a replacement (along with a replacement O-ring) and the tool is good as new. Obviously a light load application so not a test of durability but I have a good impression from the packing and shipping and overall polish of these bearings that this is a quality product.

Watch Repair

I use them to make adjustable triggers for the classic Russian Mosin Nagant Battle Rifles.

I can't vouch for the precision or load handling of these bearings. I'm using them in a switch where the bearing slides in a groove to create a postion detent. The bearings arrived quickly and they were neatly packaged and for my needs they do the job well.
