K14020AR0 Bearing Product Overview & Core Advantages
The K14020AR0 is a metric angular contact ball bearing from the Reali-Slim mm Metric Bearings series, featuring a thin-section design with a single row construction. Engineered for applications requiring high precision and space optimization, this bearing excels at handling combined loads—simultaneously supporting significant radial loads and substantial axial loads in one direction, thanks to its defined 30° contact angle. Manufactured to ABEC-1 precision standards, it delivers reliable performance in compact assemblies where high rigidity and accurate rotation are critical.

K14020AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a width of only 20 mm relative to its bore and outside diameters, this bearing enables compact, lightweight machinery designs without sacrificing performance.
High Load Capacity: The single row angular contact construction and 30° contact angle provide excellent capability for handling combined radial and axial loads. It offers a radial dynamic load rating of 4907 lbf and a substantial axial static load rating of 11309 lbf.
Precision & Rigidity: Built to ABEC-1 tolerance class with tight dimensional tolerances on the bore, outside diameter, and width. The brass cage ensures stable ball guidance, contributing to smooth operation and high rigidity.
Material & Lubrication: Components are manufactured from chrome steel for high durability and fatigue resistance. The bearing comes pre-lubricated and is suitable for a temperature range of -30°C to 110°C.
K14020AR0 Bearing Typical Application Areas
The K14020AR0 is ideally suited for applications demanding a compact footprint and high precision under combined loading conditions. Key industries and equipment include:
- Robotics: Joint and actuator bearings.
- Aerospace & Defense: Control mechanisms, radar platforms, and gimbal systems.
- Medical Equipment: Imaging devices (CT/MRI scanners) and surgical robots.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Industrial Automation: Rotary tables, indexing heads, and precision gearboxes.
