Miniature aluminium curved jaw flexible couplings.
Discs (either red as standard with blue or white optional) are available to purchase separately. Flexible couplings transmit torque and rotational angle while absorbing misalignment. When the misalignment exceeds allowable values, vibration may result or the life of the coupling may become shortened. Zero backlash in low torque application, made capable by having the hubs pressed in a spacer. Can be used as a flexible coupling in a high torque application.

Where alternative bearing options are offered, we make no claims as to the suitability of the alternatives. Selection of the most suitable bearing is the responsibility of the customer. It is usually best to replace a bearing with the same type if that type is working well. High speed caged bearings are better suited to handle vibration than standard caged bearings.

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.
