Thin section bearing

Extremely thin-section ball bearings and roller bearings contributing to downsizing, weight saving, and reduction of torque loss of robots, construction equipments, and industrial machinery.
Features
Low frictional and irregular torque ensure highly efficient power transmission and smooth rotating performance.
The high accuracy of the bearings enables excellent high-speed performance
