Bimetal bearings are a type of oil-free sliding bearing designed to provide excellent performance in demanding environments. These bearings are constructed using a high-quality low-carbon steel backing, which is then sintered with lead-tin bronze. Through multiple stages of high-temperature sintering and fine rolling, the copper and steel are bonded together to form a strong, durable bimetallic strip.
One of the key advantages of bimetal bearings is their high contact strength, large load capacity, and superior wear resistance. They are particularly well-suited for medium-speed, medium-load applications as well as low-speed, high-load conditions. Thanks to a specialized manufacturing process, oil grooves and oil holes can be precisely machined into the friction surface, allowing for optimal lubrication under various operating conditions.
These bearings have found widespread use in automotive engines, chassis systems, motorcycle clutches, gear pumps, and lifting equipment. Their versatility and reliability make them a popular choice in a variety of industrial settings.
Another variant, the metal-based inlaid solid self-lubricating bearing (commonly known as JDB), combines the benefits of both traditional metal bearings and self-lubricating bearings. It features a metal substrate that supports a specially formulated solid lubricant material. This unique combination provides excellent wear resistance, impact resistance, and heat resistance, making it ideal for heavy-duty applications involving low speeds, reciprocating motion, or rocking loads. These bearings are also resistant to water and acid corrosion, further enhancing their durability.
Users have reported that inlaid bearings not only improve fuel efficiency and energy savings but also offer a longer service life compared to conventional sliding bearings. Today, these bearings are widely used in metallurgical continuous casting machines, rolling mills, mining equipment, ships, steam turbines, hydraulic turbines, injection molding machines, and production lines.
In summary, bimetal bearings represent an advanced solution for industries requiring reliable, long-lasting, and efficient bearing technology. Whether in automotive, industrial, or marine applications, they continue to prove their value through superior performance and adaptability.
