Ball bearings use the low-friction rolling of balls to realize the smooth rotation of the shaft and the efficient transmission of kinetic energy to the various parts of the machine. This contributes to energy savings, longer life and reduction of breakdowns for the machinery. A precision of the bearings is linked directly to a precision of the machinery.

Ball bearings consist of four components – an outer and inner ring, a retainer, and the balls. The outer and inner rings support the rotational motion, the balls reduce the friction from that rotational motion, and the retainer keeps the balls in place. Lubricant is also added to make the movement even smoother, and some form of shielding is applied to prevent the lubricant from leaking.

MinebeaMitsumi’s greatest strength lies in single row radial deep groove ball bearings with external diameters up to 22mm.

MinebeaMitsumi partnered with our steel suppliers to develop a ball bearing using an innovative new material that is 20 times more resistant to rust and corrosion than ordinary stainless steel bearings. This bearing material is ideal for applications that may be exposed to saltwater, harsh weather or chemicals such as fishing reels and marine equipment, weather meters and medical devices. Using GP bearings in high corrosion applications can largely reduce defects and maintenance for end products thus increasing overall customer satisfaction.
