KAA15AG0 Bearing Product Overview & Core Advantages
The KAA15AG0 is a thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. This single-row bearing excels at handling combined loads, particularly substantial axial loads in one direction, thanks to its defined 30° contact angle. Manufactured to ABEC-1 precision standards with a lightweight nylon cage, it offers reliable performance in compact assemblies where weight and cross-section are critical constraints. Its pre-lubricated design ensures immediate operation and long service life.
KAA15AG0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KAA | Indicates the Reali-Slim® angular contact bearing series with a 30° contact angle. |
| 15 | Specifies the bore diameter in inches (1.5"). |
| A | Denotes the specific internal design and contact angle. |
| G | Specifies the radial internal clearance group. |
| 0 | Indicates an open (non-shielded) bearing, allowing for custom lubrication schemes. |
KAA15AG0 Bearing Structural Features & Performance Benefits
- High Load Capacity in Minimal Space: The thin-section design (0.1875" width) provides a large bore relative to the overall cross-section, enabling compact and lightweight machinery designs without sacrificing performance.
- Superior Axial Load Handling: The 30° contact angle is optimized to support high axial static loads (560 lbf), making it ideal for applications with significant thrust forces.
- Precision & Smooth Operation: The nylon cage reduces weight and friction, contributing to smoother running and lower operating temperatures. The ABEC-1 tolerance ensures consistent and precise rotational accuracy.
- Robust Construction: Manufactured from chrome steel for both rings and balls, this bearing offers high strength, durability, and resistance to wear.
- Optimized for Versatility: The open design allows for application-specific lubrication, while the standard pre-lubrication facilitates immediate startup.
KAA15AG0 Bearing Typical Application Areas
This bearing is engineered for high-performance applications where space and weight are at a premium. Key industries and equipment include:
- Aerospace & Defense: Gimbal systems, rotor heads, and flight control mechanisms.
- Semiconductor Manufacturing: Robotic arms, wafer handling equipment, and precision stages.
- Medical Equipment: Surgical robots, MRI scanners, and diagnostic instrumentation.
- Industrial Automation: Multi-axis robots, rotary tables, and precision gearboxes.
