K20013AR0 Bearing Product Overview & Core Advantages
The K20013AR0 is a single row angular contact ball bearing engineered for applications demanding high precision and compact design. As part of the Reali-Slim mm Metric Bearings series, it features a thin cross-section, making it ideal for space-constrained installations. This bearing is designed to handle significant combined loads, including radial and single-direction axial loads, thanks to its specific 30° contact angle. Manufactured to ABEC-1 tolerance standards, it offers reliable performance in high-precision machinery. Its chrome steel construction and optimized geometry provide excellent durability and operational stability.

K20013AR0 Bearing Structural Features & Performance Benefits
This bearing's performance is defined by its specific construction:
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides excellent resistance to combined loads, supporting a radial dynamic load rating of 3254 lbf and axial static load rating of 7899 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control on the bore diameter (200 mm) and outside diameter (226 mm), ensuring consistent performance in precision applications.
- Optimized Material Selection: Components made from chrome steel (rings and balls) and a brass cage provide high strength, wear resistance, and stable operation across the specified temperature range of -30°C to 110°C.
- Space-Saving Design: With a minimal width of 13 mm and thin cross-section, it is ideal for applications where space and weight (0.62 kg) are critical constraints without sacrificing load capacity.
K20013AR0 Bearing Typical Application Areas
