SF065AR0 Bearing Product Overview & Core Advantages
The SF065AR0 is a precision angular contact ball bearing engineered for applications demanding high performance in inch dimensions. This single row bearing features a 30° contact angle, optimized to support significant combined loads—handling both radial and axial forces simultaneously. Manufactured from stainless steel with a brass cage, it offers excellent corrosion resistance and reliable operation. Its ABEC-1 precision class and tight dimensional tolerances ensure high running accuracy, making it ideal for high-rigidity and precision positioning systems.
SF065AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF065 | Indicates a thin-section bearing series with a 6.5" bore diameter. |
| A | Signifies a 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies the internal clearance group (0.0000 – 0.0005"). |
SF065AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 30° contact angle provides exceptional stiffness and can support high combined radial and axial loads, with a static axial load rating of 11,220 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with extremely tight bore and OD tolerances, ensuring smooth, precise rotation and minimal runout for accurate applications.
- Corrosion-Resistant Construction: Rings and balls made from stainless steel provide superior resistance to corrosion, while the brass cage ensures stable operation and durability.
- Optimized for Thin-Section Applications: With a cross-section of only 0.75" on a large 6.5" bore, this bearing is a Reali-Slim series component, saving space and weight (2.94 lbs) without sacrificing performance.
SF065AR0 Bearing Typical Application Areas
- Aerospace & Defense: Gimbal systems, radar platforms, and precision instrumentation.
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and indexing tables.
- Medical Equipment: MRI and CT scanner rotors, surgical robot arms.
- Industrial Automation:** Rotary tables, robotic joints, and precision gearboxes.
