Flanged extra-miniature/miniature/small bearings
Characteristics
Extra-miniature, miniature and small ball bearings of this type have flanges on their outer rings to make positioning in the axial direction easy, and they achieve economy by eliminating the need to spotface the housing edges.
This type is ideal for parts that require high-speed rotation, low-friction torque and low-vibration/noise for devices that should be smaller, thinner and lighter-weight.
