SD080AR0 Bearing Product Overview & Core Advantages
The SD080AR0 is a high-precision Angular Contact Ball Bearing engineered for demanding applications requiring superior performance in thin section designs. Manufactured from corrosion-resistant Stainless Steel, this single-row bearing is optimized to handle significant combined loads, including high thrust capacities in one direction. Its inch-dimensioned, compact cross-section (8" x 9" x 0.5") makes it an ideal solution for space-constrained assemblies where weight reduction is critical, without compromising on load rating or rigidity. The bearing comes pre-lubricated and is built to ABEC-1 precision tolerances, ensuring reliable operation and long service life.
SD080AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD | Indicates the Reali-Slim series of thin-section bearings. |
| 080 | Specifies the bore diameter in inches (8 inches). |
| A | Denotes a 30° contact angle, optimized for handling high axial loads. |
| R | Signifies the use of a Brass (ribbon-type) cage for strength and stability. |
| 0 | Indicates an Open (unsealed) design, allowing for custom lubrication schemes or operation in clean environments. |
SD080AR0 Bearing Structural Features & Performance Benefits
The SD080AR0's performance is derived from its specific structural design:
- High Load Capacity & Rigidity: The 30° contact angle and robust single-row design provide excellent resistance to combined radial and axial loads, with a high axial static load rating of 6510 lbf. The full complement of balls and precise geometry contribute to its high static load moment capacity of 19,380 lbf.
- Precision & Smooth Operation: Manufactured to ABEC-1 tolerance class with a tight radial internal clearance (0.0000" – 0.0005"), this bearing ensures running accuracy and minimizes vibration.
- Corrosion Resistance & Durability: Both the rings and balls are made from Stainless Steel, making the bearing suitable for applications exposed to moisture or corrosive environments. The brass cage offers excellent durability and guidance.
- Pre-lubricated for Immediate Use: The bearing is supplied with grease, facilitating immediate installation and initial operation within its specified temperature range of -30°C to 110°C.
SD080AR0 Bearing Typical Application Areas
The SD080AR0 thin section bearing is ideally suited for applications where a large diameter is required within a minimal cross-section. Key industries and equipment include:
- Aerospace & Defense: Gimbals, rotor heads, and control mechanisms.
- Semiconductor Manufacturing: Robotic arms, wafer handling systems, and precision stages.
- Medical Equipment: MRI and CT scanners, surgical robots.
- Industrial Automation: Rotary tables, precision indexing drives, and robotic joints.
- Optical and Instrumentation: Telescope mounts, high-precision rotary sensors.
