KG080AR0 Bearing Product Overview & Core Advantages
The KG080AR0 is a high-performance thin-section angular contact ball bearing designed for applications requiring exceptional precision and space optimization. Manufactured to ABEC-1 precision standards, this single-row bearing excels at handling combined radial and axial loads simultaneously due to its specific 30° contact angle. Its Reali-Slim open construction provides a superior stiffness-to-weight ratio, making it ideal for compact, high-accuracy systems where minimizing cross-section is critical while maintaining robust load capacity.
KG080AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KG080 | Indicates the bearing series and size: 8" bore diameter, 10" outside diameter, 1" width. |
| A | Signifies Angular Contact design with a 30° contact angle for combined load handling. |
| R0 | Denotes Standard Radial Internal Clearance (0.0000 – 0.0005"). |
| Open | No seals or shields, allowing for custom lubrication schemes and high-speed operation. |
KG080AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The Reali-Slim construction minimizes bearing cross-section (1" width) without sacrificing strength, enabling compact and lightweight machinery designs. This is crucial for applications where space and weight are at a premium.
Superior Load Capacity: The 30° contact angle and robust single-row design enable the bearing to support significant combined loads. It offers a high radial dynamic load rating of 8566 lbf and an exceptional axial static load rating of 20180 lbf, providing reliable performance under complex loading conditions.
High-Precision Performance: Manufactured to ABEC-1 tolerance class with tight dimensional controls (bore/OD tolerance: -0.0012" to 0"), this bearing ensures smooth, precise rotation with minimal runout, which is vital for high-accuracy applications.
Durable Material Construction: Components made from Chrome Steel (rings and balls) and a Brass cage provide excellent wear resistance, dimensional stability, and reliable operation within a temperature range of -30°C to 110°C.
KG080AR0 Bearing Typical Application Areas
- Aerospace & Defense: Gimbal systems, radar platforms, and flight control mechanisms where precision and thin sections are critical.
- Industrial Robotics: Robot arm joints, rotary actuators, and precision positioning stages requiring high rigidity and compact design.
- Medical Equipment: CT scanners, MRI systems, and surgical robot arms demanding smooth, precise motion and reliability.
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and other cleanroom equipment where accuracy and minimal particle generation are essential.
- Optical & Instrumentation Systems: Telescope mounts, rotary tables, and precision measuring devices benefiting from high load capacity and low deflection.
