White metal bearings and bimetallic bushings, with a steel backing and AlSn20Cu material, offer exceptional performance in a wide range of industrial applications. The combination of steel and AlSn20Cu alloy provides a strong and durable foundation for the bearing or bushing, while the white metal material offers excellent wear resistance and self-lubricating properties.

The steel backing provides the necessary structural support and stability for the bearing or bushing, ensuring it can withstand the rigors of heavy loads and high-speed operation. The AlSn20Cu alloy, on the other hand, is a highly wear-resistant material that is capable of maintaining its performance under extreme conditions.

The white metal material itself is a type of bearing alloy that is known for its self-lubricating properties. This means that it does not require additional lubricants to function effectively, further reducing maintenance requirements and extending the life of the bearing or bushing.

Bimetallic bushings, in particular, are designed with a steel backing and an overlay of AlSn20Cu alloy. This combination allows for precise machining and fitting, ensuring a tight and reliable fit between the bushing and its mating surface. The overlay of AlSn20Cu alloy also provides the necessary wear resistance and lubricity to handle demanding applications.

In summary, white metal bearings and bimetallic bushings with steel backing and AlSn20Cu material offer a reliable and long-lasting solution for industrial applications requiring high performance and durability. Their unique combination of materials ensures superior wear resistance, self-lubricating properties, and structural stability.

Mounting advise

Housing: Mounting bevel min. 1.5 mm x 15-45°

Shaft: Mounting bevel 5 mm x 15°, edges rounded.
The application of an fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.

Bearing & Bushes

Bimetal bearing & bushes made up of white metals are manufactured keeping in mind the desired properties like wall thickness, interference fit, locating tangs, free spread, grooving configuration and clearance.

bimetallic strip a strip made of two or more layers of metal with different expansion coefficients that can be combined and processed.

In general, hot rolling, cold rolling and hot pressing are used to compound, and the alloy with low melting point can be cast to the solid metal layer with high melting point for compound.The composite method depends on the properties of the component metal and the application conditions of the bimetal.

Manufacturing technology of aluminum tin bearing alloy bimetallic strips Thin wall bearing (hereinafter referred to as the bearing shell) is one of the main vulnerable components of internal combustion engine, its variety and large output, as the internal combustion engine technical indicators (such as speed, power, etc.), the increase of demand bearing has a high bearing capacity, white metal (tin base alloy or lead white white metal) bush bearing capacity can not meet the requirements, prompted bimetal strip copper base alloy (continuous casting or sintering) successful development and application of manufacturing technology.But this kind of alloy shell, because of its surface properties (such as compliance, embedded hidden sex, etc.), therefore, the need to set up a thickness of about 0.02 ~ 0.05 mm pewter binary alloy or ternary alloy surface coating, to improve the performance of bearing surface to meet the requirements of bearing working reliability, obviously, this will increase the manufacture cost of bearing, and leads to some problems such as environmental protection, thus, force bearing shell companies and scholars to research and development at home and abroad with medium AlSn20Cu surface of bearing capacity and the good performance of bearing alloy (Sn 17.5 ~ 22%,Cu is 0.7 ~ 1.3%, the rest is Al) and its bimetallic belt manufacturing technology.
