SA080AR0 Bearing Product Overview & Core Advantages
The SA080AR0 is a high-performance thin section bearing designed for applications requiring precision and space optimization. As a single row angular contact ball bearing manufactured from stainless steel, it excels in handling combined loads, particularly thrust loads in one direction due to its specific contact angle. Its compact cross-section (0.25" width) and ABEC-1 precision make it an ideal solution for high-accuracy, lightweight assemblies where reliability is critical.
SA080AR0 Bearing Model Code Explained, Specifications & Naming Convention
The SA080AR0 model number provides key technical specifications:
- SA: Indicates a Stainless Steel construction for the rings and balls, offering excellent corrosion resistance.
- 080: Specifies the bore diameter of 8 inches.
- A: Denotes the Angular Contact design with a 30° contact angle, optimized for combined radial and axial loads.
- R0: Signifies an Open (non-shielded) seal type, allowing for custom lubrication schemes and high-speed operation.
SA080AR0 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its specific engineering:
- High Load Capacity & Rigidity: The single row angular contact design and 30° contact angle provide superior resistance to combined loads, with a high axial static load rating of 2280 lbf. The brass cage ensures stable operation under load.
- Precision & Accuracy: Manufactured to ABEC-1 tolerance class with tight dimensional control on the bore, outside diameter, and width, ensuring predictable performance and ease of integration into precision mechanisms.
- Space & Weight Savings: As part of the Reali-Slim series, its thin section profile (0.25" width) allows for more compact and lightweight designs without sacrificing load capacity.
- Corrosion Resistance & Durability: The all-stainless steel construction (rings and balls) ensures long-term performance in harsh or wash-down environments, compliant with ROHS standards.
SA080AR0 Bearing Typical Application Areas
The SA080AR0 is ideally suited for a wide range of demanding applications, including:
- Robotics and Automation: Joints, actuators, and rotary tables where precision, compactness, and reliable angular contact performance are required.
- Aerospace and Defense: Guidance systems, control mechanisms, and instrumentation benefiting from its lightweight thin section and stainless steel construction.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic devices that demand high cleanliness, corrosion resistance, and precise motion control.
- Semiconductor Manufacturing: Wafer handling robots and precision stages utilizing its ABEC-1 precision and ability to handle combined loads.
