Solid turned bronze sliding bearing
We do not have the BRO-MAS® bronze sliding bearing in stock – we make each one individually for your dimensions and your individual needs. This guarantees that our sliding bearing meets the highest requirements and remains in service as long as possible. Despite the production on request, you do not have to wait long for your order: We deliver the BRO-MAS® bronze sliding bearing at short notice, regardless of which special size you have requested.
We normally make our lathed BRO-MAS® bronze sliding bearings from the standard material CuSn12, which is composed of 85 to 88.5 percent copper and 11 to 13 percent tin and up to 2 percent nickel. Other materials are also available in this product group on request, for example, when the sliding bearing is used in temperature ranges that exceed the recommended 150°C. CuSn12 is very resistant to wear and tough, with good resistance to corrosion, especially from sea water. Our bronze sliding bearing also has the following properties:
As already noted above, as the customer you specify which individual tolerances the specified bronze sliding bearing should meet according to your needs. This applies to the diameter of the housing bore, the tolerance of the bushing after installation, as well as the shaft tolerance. However, there is hardly any choice of shaft material. It should be hardened steel with a roughness depth of less than 6.3 Rz. For the BRO-MAS® bronze sliding bearing, regular maintenance is critical, which in the first instance involves careful lubrication with oil or grease. If you use additional lubrication grooves or lubrication holes, the lubricants are better distributed and you can greatly reduce the number of maintenance intervals required. If you follow these recommendations, your individually manufactured bronze sliding bearing will provide you with a long service life, regardless of whether it is used in construction and agricultural machinery or in vehicle, equipment and machinery construction.
* On request further materials are available for higher demands, e.g. for higher temperature ranges.
** The above stated material properties are valid for optimal operating conditions. Through changes of the application conditions e.g. higher sliding speed or strain, these values are subject to change.
