Bimetal bearings are sliding bearings primarily constructed from two distinct metal layers bonded together, combining the advantageous properties of each material. Thanks to this composite structure, they exhibit excellent wear and friction resistance, corrosion resistance in certain combinations, and the ability to withstand a wide range of operating temperatures. There are various types: self – lubricating bimetal bearings incorporate lubricating elements or coatings to function effectively with minimal external lubrication; those designed for high – load applications have a robust base metal layer with a specialized overlay to bear substantial weights; and corrosion – resistant bimetal bearings use metals that are highly resistant to chemical attack for use in harsh environments.

Bimetal bearings find extensive applications across numerous industries. In the automotive sector, they are installed in engines, transmissions, and chassis components to reduce wear, enhance operational efficiency, and handle the stresses and impacts encountered during vehicle operation. In industrial machinery, they are used in heavy – duty equipment such as pumps, compressors, and gearboxes to ensure reliable performance under high – load and continuous – operation conditions. These bearings offer a long service life, which reduces the frequency of replacements and associated downtime, along with low maintenance costs. Many manufacturers also provide custom – designed bimetal bearings to precisely meet the specific requirements of different customers and applications.
