村上製作所 List of Products and Services

Murakami Manufacturing Co., Ltd. designs and develops according to application needs. We respond to high-demand processing requirements with a consistent system from alloy casting. Full-floating bearings for turbochargers are made from an alloy based on brass, with cutting processing and surface treatment to enhance functions such as wear resistance. The turbo metal, which can be considered the heart of high-performance turbo engines, has an inner diameter of just 6mm, yet incorporates various high-functionality elements within its simple shape.

Murakami Manufacturing Co., Ltd. designs and develops products according to their intended use. We respond to high-demand processing needs with a consistent system from alloy casting. Turbochargers, as they are translated as superchargers, send pressurized air or mixed gas into the cylinder and utilize exhaust pressure to improve fuel efficiency and horsepower. However, because they operate at high rotational speeds, the components are subjected to high load pressures. In recent years, turbochargers have gained attention as part of diesel engine exhaust purification and fuel-saving measures, and there is a tendency for production volume at Murakami Manufacturing to increase rapidly.

Murakami Manufacturing Co., Ltd. designs and develops products according to their applications. We respond to high-demand processing needs with a consistent system from alloy casting. Compressor impellers are very delicate products that require dynamic balance, and two-surface correction to achieve balance on both sides demands a high precision with an eccentricity tolerance of 0.5 microns. Bearings are collectively referred to as "bearings" in English, and different types such as sliding bearings, ball bearings, and static pressure bearings are used depending on the application. Among these, "sliding bearings" operate with relative sliding through a thin film created by lubricating oil, and Murakami Manufacturing boasts the largest production volume in the industry for automotive crank washers.
