Micro-motor bearings for digital device and information device

With precision motors used to implement subtle and complicated motions in high-tech devices taken as an example, a sintered oil-impregnated bearing, which is a major Peace-lon product, can properly receive rotations of those motors. Peace-lon bearings play active roles behind the scenes as important parts that are vital to performance of those motors, and even of the devices themselves.

Having a line up of 250 and more, and 200 to 300 million pieces manufactured monthly, Peace-lon can be described as a driving force behind high-tech industry.
