SA065AR0 Bearing Product Overview & Core Advantages
The SA065AR0 is a Reali-Slim Stainless Steel Angular Contact Ball Bearing engineered for applications requiring exceptional precision and reliability in compact spaces. This single row bearing is specifically designed to handle combined loads, accommodating significant radial loads and one-direction axial loads due to its defined 30° contact angle. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance. Its thin-section design (0.25" width) provides a high load capacity within a minimal cross-section, making it ideal for weight and space-sensitive applications demanding high rigidity and smooth operation.
SA065AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SA | Stainless Steel, Angular Contact | Indicates the bearing is constructed from corrosion-resistant stainless steel and is of the angular contact type. |
| 065 | Bore Diameter (6.5 inches) | Specifies the precise inner diameter of the bearing. |
| A | 30° Contact Angle | Denotes the standard contact angle, optimized for handling combined radial and axial loads. |
| R0 | Radial Internal Clearance (R0 group) | Specifies a very small, precision radial internal clearance (0.0000 – 0.0005"), suitable for applications requiring high running accuracy. |
| (Implied) | Open, Lubricated | The bearing comes without seals (open) and is pre-lubricated, allowing for custom re-lubrication strategies. |
SA065AR0 Bearing Structural Features & Performance Benefits
Thin-Section, High-Capacity Design: The bearing's slim 0.25" width and large 6.5" bore provide a superior stiffness-to-weight ratio, enabling robust performance in compact assemblies. This thin-section bearing design is critical for saving space without compromising on load capacity.
Superior Load Ratings: With a radial dynamic load rating of 788 lbf and a high axial static load rating of 2000 lbf, this bearing is built to withstand demanding operational stresses. The 30° contact angle is key to its efficient handling of combined loads.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with a very tight radial internal clearance, this precision bearing ensures smooth, low-vibration, and high-accuracy rotation, which is essential for sensitive equipment.
Corrosion Resistance & Durability: The use of stainless steel for all bearing components and a brass cage provides excellent resistance to corrosion and ensures reliable performance in challenging environments, from -30°C to 110 °C.
SA065AR0 Bearing Typical Application Areas
The SA065AR0 is ideally suited for a wide range of high-precision and space-constrained machinery, including:
- Robotics and Automation: Rotary joints, actuator arms, and precision gearing systems.
- Aerospace and Defense: Guidance systems, radar platforms, and instrumentation.
- Medical Equipment: MRI and CT scanner gantries, surgical robots, and diagnostic devices.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Imaging Systems: Precision rotary tables and mirror mounts.
