NSK has developed a mine conveyor bearing with an integrated seal. The bearing features water resistance three times that of the company's existing product. In addition, it has a structure with enhanced hermeticity to prevent the ingress of dust.
NSK plans to market it around 2010, aiming for annual sales of 200 million Yen.
The low-torque, highly hermetic bearing has been designed for use in conveyor rollers, demand for which is increasing for mine development in Australia and South America.
