Smallparts Balls - Technical Information

Balls

People often refer to balls as "ball bearings". This is incorrect. A ball is just a ball. Ball bearings contain balls just as roller bearings contain rollers. Balls and rollers are known as the "rolling elements" of a bearing.

Balls are used in many applications other than bearings. Some examples include valves, floating covers, decoration, ball transfers and the retractable ends in ball plungers. SPB provides balls in many materials including steels, plastics and ceramics. Ball material and precision should be selected in accordance with the requirements of the project at hand - see the links to the tables below.

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.

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, Gearboxes Information and General Engineering Parts Information.
