New Bearing-making Technology Developed

A porous cast iron sleeve bearing-making technology of great economic value is widely used in the machine-building industry sector of the DPRK.

The sleeve bearing is made of expensive nonferrous metal and its melting, moulding and machining processes are very complicated, with large power consumption.

The new technology makes it possible to make the sleeve bearing on the spot promptly with low production cost as its main raw material is cast iron shavings.

The bearing with a long serviceable life can be applied to various machines according to its uses.
