HiPicco 698ZZ Deep Groove Ball Bearings, ID 8mm x OD 19mm x Width 6mm Miniature Bearings, Double Metal Shielded Ball Bearing Chrome Steel Z2 Lever 20pcs

Good part and good price.

- Good dimensional accuracy and consistency.- Made of quality, hardened steel. A file skates over.- Rolling resistance is as expected for lubed, shielded bearing this size.

Good quantity for the price. The dimensions are accurate. The bearing faces were well finished. For a quick threaded mount, 5/16"SAE was a little loose but depending on what you are doing, it could work. 3/8"SAE was definately too big. M8 was similar to 5/16".In all, they are nice little project bearings.

These bearings a very nice bearings for a good price! The roll very smoothly and work great in my project. My only complaint, is that that they were packaged in a small ziplock bag and not in a tube or anything else and the bag split inside the padded shipping envelope I received them in. Fortunately, all the bearings were there and undamaged but the need to be more securely packaged in the first place. Preferably in a tube like most miniature bearings are packed.

Nice little bearings. I'm using them in 3D printed contraptions, work well with the 2mm screws.
