Materials

Standard materials used for the races of our miniature ball bearings are AISI440C Stainless Steel and SAE52100 Chrome Alloy Bearing Steel

AISI440C Stainless Steel bearings are heat treated to a hardness usually from Rockwell C 58 to Rockwell C 61+. All RMB German Product is manufactured to a minimum of Rockwell C 61. The maximum recommended operating temperature is 177^o Celsius (350^o Farenheight).

SAE52100 chrome steel Bearings are usually slightly harder than AISI440C bearings. RMB heat treats their SAE52100 chrome steel bearings to Rockwell C 61-64. The maximum recommended operating temperature of chrome steel bearings is 120^o Celsius (248^o Farenheight).

Operating temperatures higher than those shown above will need special treatment. Please consult SPB.

See our sections on seals and shields and cages for information about the materials used in these parts.

Bearings for very corrosive environments are made from 316 stainless steel or acetal, but it must be noted that tolerances for these bearings are not as precise as for AISI440C or SAE52100. The available range of these types is limited.

The materials listed below cover some of the standard materials used in the SPB product range. Not all materials are available for bearings. When you click into each material you will see a list of standard SPB products to which that particular material relates.

Site Summary:

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, Gearboxes Information and General Engineering Parts Information.
