The term bimetal refers to a composite material made by bonding one of a variety of special bearing layers onto a plate steel base. Daido Metal’s atomic-level bonding technology includes sintering, pressure welding, casting and impregnation. We manufacture bimetals of all characteristics, using copper alloys, aluminum alloys, polymers and other materials. The foundation of our high-quality bearings is in the development of these bimetal materials. These capabilities are the main reason the Daido Metal brand is so well respected.
Bimetal materials must undergo forming technology to produce high-performance bearing products. Extremely precise machining is required at this stage, whether press cutting, press working to form parts into half-bearings or cylindrical shapes or finishing to optimal thickness are being performed. We design and manufacture in-house our own press molds and dedicated machinery. Because we employ technology accurate to the micron level, we are able to produce high-quality bearings with consistent reliability.
Smooth motion depends upon the condition of the surfaces where friction occurs, with the overlay covering the bearing layer playing a crucial role. Daido Metal is continually developing overlays and improving production methods, and has established a surface treatment technology for creating uniform, highly precise films. We are also actively engaged in developing new surface treatment technologies.
In order to propose the most suitable bearing for the customer,
it is important to accurately predict the conditions to which the
bearing will be exposed by theoretically calculating the oil film
pressure applied to the bearing etc. By utilizing various analysis
software such as EHL, FEM, CFD, etc., it is possible to design an
optimum bearing that will not cause bearing damage. This also
contributes to shortening the development period. Analysis
engineers are located not only in Japan, but also in Europe and
North America to respond to customer needs.
