10 Balls 1/4 inch=6.35mm Loose Ceramic Balls G5 Si3N4 Bearing Balls

I'm an artist and need ball bearings for my projects. Nothing technical so I can't speak to the actual use as a bearing. However, the website and searching are excellent. Delivery is excellent.

This is a wonderful company it’s easy to use their website they have both metric and US measurements.
Quality is exellent. Highly recommend!😬😬😬

After upgrading the rear hub on my cyclocross bike I can now go at least 2 to 3 miles per hour faster than before the upgrade. These are really great low friction bearings and make a really big difference when used with the correct type of grease--ceramic bearing grease.

I had a set of older hubs with cup and cone type bearings. Some of the balls were scarred and the races were getting scarred as well. Since Ceramic Si3N4 balls are so much harder and more perfectly rounded than steel and don't scar like steel, they clean and smooth the races nicely. So I replaced all the steel with nice ceramics front and rear. They are rolling much nicer now and they only get faster with time and use.

Easy installation into races and smoother operation with less wear.
