At AUB, we have a wide selection of miniature ball bearings for you to choose from. Metric, inch, standard, flanged, open, sealed, shielded, chrome steel, stainless steel – plus a range of miniature thrust ball bearings. Miniature bearings are used in many applications such as remote control models, gyroscopes, miniature gearboxes, small motors, small instruments, dental equipment, vacuum cleaners, scooters, skateboards, fishing reels, etc.
With such a large application, it should come as no surprise that we now have an inventory of nearly 1 million miniature bearings in several thousand different types. View our bearing specification sheets detailing all the sizes and varieties we offer, with bore sizes as small as 1.0mm in metric sizes. Similar to the inch series miniature bearings, the metric series bearings offer high precision ABEC 3, 5 and 7 tolerances and are available with different radial clearances. Here you'll find standard sizes, weights and speeds to help make the right selection for your application.
