SG080AR0 Bearing Product Overview & Core Advantages
The SG080AR0 is a high-performance thin section bearing engineered for applications demanding precision and reliability in compact spaces. As a single row angular contact ball bearing, it is specifically designed to handle combined loads, efficiently supporting significant radial loads and axial loads in one direction. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and smooth operation. Its ABEC-1 precision class and optimized 30° contact angle make it an ideal choice for high-accuracy, high-rigidity systems where space and weight are critical constraints.
SG080AR0 Bearing Model Code Explained, Specifications & Naming Convention
The model number SG080AR0 can be broken down to reveal its key technical specifications:
- SG: Indicates the Reali-Slim thin section bearing series.
- 080: Specifies the bore diameter in inches, which is 8 inches.
- A: Denotes the Angular Contact design, optimized for combined loads.
- R0: Signifies a standard radial internal clearance and Open (unsealed) construction.
SG080AR0 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row angular contact design, combined with a 30° contact angle and a robust brass cage, provides exceptional stiffness. This enables the bearing to handle high radial dynamic load ratings of 8566 lbf and significant axial static load ratings of 20180 lbf.
- Precision Performance: Manufactured to ABEC-1 tolerance standards with a tight radial internal clearance (0.0000" – 0.0005"), this bearing ensures smooth, precise rotation with minimal runout, which is critical for high-accuracy applications.
- Corrosion Resistance and Durability: Constructed entirely from stainless steel (rings and balls), the bearing is inherently resistant to corrosion, making it suitable for harsh environments and extending its service life.
- Compact and Lightweight Design: As part of the Reali-Slim series, it features a thin cross-section (1" width for 8" bore), saving significant space and weight (6.54 lbs) without compromising performance.
SG080AR0 Bearing Typical Application Areas
This bearing is ideally suited for a range of demanding applications, including:
- Robotics and Automation: Joint and arm assemblies requiring high precision and compact design.
- Aerospace and Defense: Gimbals, control mechanisms, and radar systems where weight savings and reliability are paramount.
- Medical Equipment: High-speed scanners, surgical robots, and imaging devices demanding smooth, precise motion.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Optical and Instrumentation Systems: Rotary tables and positioning devices requiring minimal friction and high accuracy.
