Improved Bearing Alloy - A Contribution Toward Environmental Protection.
There are differences between European and US bearing metals. This paper shows the mechanism for improving the properties of bearing alloys and the environmental problems that have arisen so far in this connection. Since 1994, a new generation of bearing alloy has been on the European market, further improved, but no longer harmful to the environment. Although this is a material with a high load-bearing capacity, its plastic deformation (creeping) could be greatly reduced, so that bearing lifetime can be enhanced or its load-bearing capacity can be increased. The technology was accepted well in the marketplace and is successfully used in a wide range of European industries, e.g., for rolling-mill bearings, gears, generators, turbines, and ship propulsion. This paper compares this improved alloy with the US standard ASTM B 23-2. The advantages realized are clearly shown. Practical examples are presented, and an outlook to further improving the load-bearing capacity of bearings is given.
