K30013AR0 Bore 300 Mm, 13mm SERIES, REALI-SLIM MM Metric Series Bearings
The K30013AR0 Thin-section angular contact ball bearings are primarily used in applications with stringent requirements for weight, space, and precision, such as aerospace gyroscopes, robotic joints, medical CT scanner gantries, machine tool spindles, semiconductor manufacturing equipment, optical instruments (e.g., telescopes), and precision rotary tables.
The K30013AR0 bearing is a Thin-section bearings with an inner diameter of 300 mm , an outer diameter of 326 mm, a width of 13 mm. It typically uses Precision Class 1 (ABEC 1F) standard grade precision tolerances and GCr15SiMn rings, GCr15SiMn rolling mlement. Its dynamic radial rated load is approximately 18006 N, its static radial rated load is approximately 53763.8 N. open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
K30013AR0 bearings ( 300 mm x 326 mm x 13 mm) have the advantages of Extremely compact, lightweight design, composite load-bearing capacity, high rigidity, and flexible installation, and are therefore widely used in the Robot joints, aerospace, semiconductor equipment, medical instruments and optoelectronic turntables.

The K30013AR0 Thin-section angular contact ball bearings mainly consist of a thin-walled inner ring, a thin-walled outer ring, steel balls, and a cage. Their cross-sectional dimensions are constant and extremely thin, with contact angles typically of 15°, 25°, or 30°, making them suitable for space-constrained installations.
Thin-section angular contact ball bearings utilize a thin-walled, constant cross-section design, resulting in lightweight construction and a small footprint, effectively reducing the overall weight of equipment. They can simultaneously withstand radial and axial loads, possessing high rigidity, high-speed capability, and good positioning accuracy, and are easy to install.
