Metal-polymer bearings, also known as self-lubricating bearings, are a type of bearing that are designed to operate without the need for external lubrication. They are made from a metal backing with a layer of polymer material bonded to the surface. The polymer layer is impregnated with lubricant, which is released as the bearing moves, providing a constant supply of lubrication.

Metal-polymer bearings offer several advantages over other types of bearings. One of the main benefits is their ability to operate without external lubrication, which can reduce maintenance requirements and extend the life of the bearing. This also makes them a good choice for applications where lubrication is difficult or impossible, such as in underwater or vacuum environments.

Another advantage of metal-polymer bearings is their ability to operate in a wide range of temperatures and environments. They can withstand high temperatures and exposure to harsh chemicals, making them ideal for use in industrial applications.

Metal-polymer bearings also offer excellent resistance to wear and corrosion, which helps to ensure long-lasting performance and reliability. They are often used in high-load, low-speed applications, such as those found in heavy machinery or industrial equipment.

There are several types of metal-polymer bearings available, including those made from bronze, aluminum, and stainless steel backings. Each type has its own unique properties and is suited to different applications.

In summary, metal-polymer bearings are a versatile and reliable choice for a wide range of industrial applications. Their ability to operate without external lubrication, resistance to wear and corrosion, and ability to withstand high temperatures and exposure to harsh chemicals make them a popular choice among engineers and equipment operators.
