KA020AR0

KA020AR0 RealiSlim open thin section bearings provide exceptional running accuracy. The KA020AR0 bearing has a 2-inch bore diameter. Its outer diameter is 2.5 inches. KA020AR0 ball material is 52100 chromium steel.

KA020AR0 angular contact thin section ball bearings can withstand simultaneous radial and axial loads, with the axial load acting in only one direction. A bearing series based on a single cross-section that remains constant as the bore diameter increases, resulting in significant space and weight savings. Bearings are available in metric and imperial dimensions. Depending on the design and series, bearings can be chemically and corrosion-resistant.

KA020AR0 is an A-type thin-section bearing with a 30° contact angle. The main advantage of an A-type bearing is that it provides greater thrust capability than a C-type or X-type bearing. Type A bearings have one-way thrust capability due to their counterbored outer rings. Therefore, this bearing should be installed opposite another bearing to establish and maintain the contact angle and support reverse thrust loads.

Typical applications include:

Precision robotic joints, semiconductor equipment and measurement systems, radar and microwave equipment, solar panels, guidance systems, medical imaging equipment, machine tools, textile machinery, material handling, satellite systems, antenna equipment, packaging machinery, aerospace, scanning equipment, optics Equipment, rotary joints, manufacturing equipment, military turrets, slip ring components, harmonic drives, reducers, etc.

General selection factors

Several factors must be considered when selecting RealiSlim open thin section bearings. These factors include ring material, design, guards and seals, cages, Annual Bearing Engineering Council (ABEC) ratings, radial clearance and lubricants, among others.
