3E809KAT2 robot bearing/harmonic drive bearing is a special kind which easily deforms in a reversible way. It has a very thin outer ring which varies from round shape to oval interatively during its working time.  easily  double sealed bearing designed primarily for application of radial load—deep ball grooves also permit application of thrust load in either direction, often used in conjunction with another bearing.

BEART bearing offers a wide variety of thin section bearing styles for industrial applications.

Most radial ball bearings are designed so that as the bore size increases, the width and the thickness of the bearing changes proportionately. Thin section bearings reduce total cost in a system because the cross section remains the same as the bore diameter increases, thereby improving design efficiency over standard bearing geometries. Modern designs rely on a compact design, low weight and miniaturization. Thin section bearings are an ideal solution. Each series of thin section bearings is based on a single cross-section that remains constant even with increasing bore diameter. This design often allows solid shafts to be replaced with hollow shafts. The interior of the hollow shaft provides space for components such as air or hydraulic lines, pneumatic lines, electrical wiring, etc. For a large number of applications, a four-point contact thin section bearing can even replace two bearings. This allows for a more compact design, simplifies the installation, and may reduce cost.
