KA065AR0 Bearing Product Overview & Core Advantages
The KA065AR0 is a thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. As part of the Reali-Slim Open Bearings series, its single-row design is specifically configured to handle significant combined loads, including radial and unidirectional thrust loads, thanks to its defined 30° contact angle. Manufactured to ABEC-1 precision tolerances, this bearing offers reliable performance in compact envelopes, making it ideal for high-rigidity systems where weight and cross-section are critical constraints.
KA065AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA065 | Bearing series designation for Reali-Slim angular contact bearings with a 6.5" bore diameter. |
| A | Signifies Angular Contact design with a 30° contact angle. |
| R0 | Indicates standard radial internal clearance (0.0000 – 0.0005"). |
KA065AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact construction with a 30° contact angle provides excellent resistance to combined loads, supporting a radial dynamic load of 788 lbf and an axial static load of 2000 lbf.
- Precision Engineering: Built to ABEC-1 tolerance class with tight bore and OD tolerances, ensuring smooth operation and accurate rotational performance in precision assemblies.
- Optimized Material Selection: Features chrome steel rings and balls for high wear resistance and durability, combined with a brass cage for superior guidance and stability at moderate speeds.
- Space-Saving Design: With a remarkably slim 0.25" width and large bore diameters, this bearing is ideal for applications where minimizing cross-section is critical without sacrificing performance.
KA065AR0 Bearing Typical Application Areas
- Robotics & Automation: Rotary joints, robotic arms, and precision positioning systems requiring high moment stiffness.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms where lightweight, thin-section components are essential.
- Medical Equipment: Imaging devices (CT/MRI), surgical robots, and diagnostic instruments demanding smooth, precise motion.
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and other cleanroom equipment requiring high accuracy and reliability.
