Using White Metals for Bearings

Bearings are used to allow parts to rotate or move within a machine or structure. Building structures use them to allow movement between two parts of the structure. Therefore, the structure can absorb loads and withstand a degree of seismic activity. Machines use gears and other rotating parts to function. Tin-based white-metal alloys are ideal for manufacturing bearings for machines. These alloys have the necessary properties to optimise their performance and durability. Technoslide is experts in the design, manufacture, and repair of these white-metal machine parts.

We offer batch production and unique one-off production of white-metal bearings for your business. Industrial businesses are aware of the perils of such a part failing in heavy and expensive machinery. Therefore, they need someone to call when a bearing is starting to fail. We can react quickly in emergency situations, ensuring fast turnaround times. Should such a part have a bore of between 25 and 1800 mm, we will be able to deliver a solution for your business. Today, we will focus on the metallic alloys used to create white metals and why they are ideal for the manufacture of machine parts.

An alloy is a combination of metals that forms a new metallic alloy with unique properties. Alloys can also be created by combining one or more metals with non-metallic elements. The combination of silver and copper results in sterling silver, which is used for exotic cutlery. White metals are alloys such as sterling silver, which are light-coloured due to the specific types of metals used to create them. For machine bearings, tin-based white-metal alloys are typically used. These alloys provide the most suitable properties in terms of friction, heat, and stability.

When we look at the different applications of white-metal bearings within the industrial sector, different alloys are used to obtain certain characteristics. For light- and medium-duty internal-combustion engines’ main and big-end bearings, the alloy would consist mostly of tin, with a small percentage of copper being added. General-purpose heavy-duty uses would see the addition of lead in the alloy, adding plasticity to its properties. Therefore, different applications require different types of white-metal alloys to create the ideal bearing for the job.
