SG047AR0 Bearing Product Overview & Core Advantages
The SG047AR0 is a thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. Manufactured from stainless steel with a 30° contact angle, this single-row bearing excels at handling combined loads, supporting significant radial and axial forces simultaneously. Its Reali-Slim design offers a compact cross-section relative to its bore diameter, making it ideal for weight-sensitive and high-rigidity applications. The bearing comes pre-lubricated and is built to ABEC-1 precision tolerances, ensuring reliable performance in demanding environments.
SG047AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates the bearing series, specifically a thin-section stainless steel bearing. |
| 047 | Specifies the nominal bore diameter in inches (4.75"). |
| A | Denotes the 30° contact angle, optimized for handling high axial loads. |
| R0 | Specifies the radial internal clearance group (0.0000" – 0.0005"). |
| Open (Seal Type) | No seals or shields, allowing for higher speeds and easy re-lubrication, but requiring a clean operating environment. |
SG047AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides excellent resistance to combined radial and axial loads, supported by high static load ratings (10,900 lbf radial, 14,970 lbf axial).
- Precision Engineering: Manufactured to ABEC-1 tolerance class with a tight radial internal clearance, ensuring smooth operation and accurate rotational performance.
- Corrosion Resistance & Durability: Constructed entirely from stainless steel (rings and balls) with a brass cage, offering superior corrosion resistance and longevity in harsh environments.
- Space-Saving Design: The Reali-Slim thin-section construction (1" width) maximizes the bore size while minimizing cross-section, ideal for compact machinery layouts.
SG047AR0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and precision positioning systems.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms.
- Medical Equipment: MRI and CT scanner gantries, surgical robot joints.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Instrumentation: High-precision rotary tables and measuring devices.
