KA065ARO Bearing Product Overview & Core Advantages
The KA065ARO is a thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. Featuring a single-row construction with a 30° contact angle, it excels at handling combined loads, particularly substantial axial loads in one direction. Its Reali-Slim design offers a minimal cross-section relative to its bore diameter, making it ideal for compact, weight-sensitive machinery. Manufactured to ABEC-1 precision tolerances, this bearing ensures reliable performance in high-accuracy systems.
KA065ARO Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K | Indicates a specific bearing series or manufacturer designation. |
| A065 | Specifies the bore diameter of 6.5 inches. |
| A | Denotes the 30° contact angle, optimized for high axial load capacity. |
| R | Signifies the Reali-Slim, thin-section construction. |
| O | Indicates an Open (unsealed) bearing, allowing for custom lubrication schemes. |
KA065ARO Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its specialized construction. The single-row angular contact design with a 30° contact angle provides exceptional axial load capacity and high rigidity for precise positioning. The thin-section design minimizes weight and space requirements without compromising on the static load moment rating of 6830 lbf. The use of a brass cage ensures stability and smooth operation at moderate speeds. Components made from chrome steel offer high durability and wear resistance. The open design allows for the application of specialized lubricants to suit specific operational environments and temperature ranges from -30°C to 110°C.
KA065ARO Bearing Typical Application Areas
- Robotics and Automation: Rotary joints and arm assemblies where space and weight are critical.
- Aerospace Actuation Systems: Control surface mechanisms and gearbox supports.
- Medical Equipment: High-precision scanners and imaging devices.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical Instrumentation: Rotary tables and positioning systems requiring minimal deflection.
