KA030AR0 Bearing Product Overview & Core Advantages
The KA030AR0 is a thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. Featuring a single-row design with a 30° contact angle, this bearing excels at handling combined loads, efficiently supporting both radial and significant axial loads in one direction. Its Reali-Slim open construction provides maximum cross-section utilization while minimizing weight and envelope size. Manufactured to ABEC-1 precision standards with premium chrome steel components, it delivers reliable performance in high-rigidity applications requiring precise rotational accuracy.

KA030AR0 Bearing Structural Features & Performance Benefits
Thin-Section Engineering: With a consistent 0.25" cross-section regardless of bore size, the KA030AR0 provides maximum bearing performance in minimal space, enabling compact machinery design without sacrificing load capacity.
Angular Contact Design: The 30° contact angle and single-row construction deliver superior axial load capacity (1230 lbf static) while maintaining excellent radial load handling (507 lbf dynamic). This makes it ideal for applications experiencing combined loading conditions.
Precision Manufacturing: Built to ABEC-1 tolerance class with tight dimensional controls (bore tolerance: -0.0006"–0"), this bearing ensures smooth operation and precise positioning. The brass cage provides superior ball guidance and stability at moderate speeds.
Material Excellence: Constructed from chrome steel for both rings and balls, the bearing offers high hardness, wear resistance, and dimensional stability across the operating temperature range of -30°C to 110°C.
KA030AR0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and positioning systems requiring high precision and compact design
- Aerospace Systems: Control mechanisms, actuation systems, and instrumentation where weight and space are critical
- Medical Equipment: CT scanners, surgical robots, and diagnostic instruments demanding smooth, precise motion
- Industrial Machinery: Rotary tables, indexing heads, and precision spindles in manufacturing equipment
- Optical and Instrumentation: Telescope mounts, measuring devices, and scientific instruments requiring minimal deflection
