Small Parts and Bearings offers over 100,000 products including small bearings, timing pulleys, timing belts, seals, o-rings, gears etc - see the full listing in the Online Catalogue. Our main business is handled primarily through our internet store or via phone, fax or mail order. To keep our prices low we have minimised overheads by not having a storefront. If you would like to deal through an MBA distributor with a showroom and counter service you can contact H.E. Supplies (Hobby Engineering Supplies).

Using the links at the top of this page you will find extensive information including catalogues (Products and Store link), technical data, and other product specific information. We sell our product worldwide through our online store and have quite low overseas freight rates.

The Small Parts and Bearings online store is linked directly to the Miniature Bearings Australia online catalogue, so all new MBA products are added automatically. Recent additions include full ceramic bearings in Silicon Nitride and Zirconia, and ceramic hybrid bearings for pushbikes and other applications. New products are being added every week. We also suggest that you may want to take a look at the technical information sites - Shafting Information, Couplings Information and Gearboxes Information. If you arelooking for hobby parts youmaylike to try H.E. Supplies Hobby Parts.
