metal or bearing metal, is any of several alloys used for the bearing surface in a plain bearing.

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.

Range Of Application

 

High sliding speed, engine construction

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.

 

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.
