This series features a metric standard medium-diameter design with enhanced load-bearing capacity. The flanged design simplifies the machining of stepped mounting holes, allowing the bearing to be mounted directly onto equipment panels. From a mechanical standpoint, the internal raceway-to-ball contact geometry has been optimized, enabling the bearing to handle radial loads as well as bidirectional axial loads.
Bearing Features
It is an ideal choice for office automation equipment—such as printer and copier rollers—that requires a balance between speed and load capacity. Precision heat-treated bearing steel ensures excellent fatigue strength, guaranteeing operational stability during frequent start-stop cycles and reducing the need for maintenance.
