SG040AR0 Bearing Product Overview & Core Advantages
The SG040AR0 is a stainless steel thin-section angular contact ball bearing designed for applications requiring high precision and corrosion resistance. This single-row bearing excels in handling combined loads, particularly significant axial loads in one direction, thanks to its defined 30° contact angle. Its Reali-Slim cross-section provides a compact and lightweight solution without sacrificing performance, making it ideal for space-constrained, high-reliability applications. Manufactured to ABEC-1 precision tolerances, it ensures consistent operation and long service life.
SG040AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates the bearing series (Reali-Slim Stainless Steel). |
| 040 | Specifies the bore diameter in inches (4.0"). |
| A | Denotes the contact angle of 30°, optimized for axial load capacity. |
| R | Signifies the use of a brass cage for strength and stability. |
| 0 | Indicates an open (unsealed) construction. |
SG040AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design, with a 30° contact angle, provides excellent rigidity and is engineered to support high combined radial and axial loads. It features a substantial axial static load rating of 13,630 lbf.
- Corrosion Resistance & Clean Operation: Constructed entirely from stainless steel (rings and balls), this bearing is ideal for harsh environments, washdown applications, and industries where corrosion is a concern. It is also RoHS compliant.
- Precision & Stability: The brass cage ensures smooth operation at moderate speeds and enhances guiding stability. Manufactured to ABEC-1 standards, it guarantees precise running accuracy.
- Standard Lubrication: The bearing comes pre-lubricated for immediate use, suitable for its specified temperature range of -30°C to 110°C.
SG040AR0 Bearing Typical Application Areas
This bearing is ideally suited for:
- Aerospace & Defense: Actuators, control systems, and gimbal mechanisms.
- Food & Beverage Processing: Conveyor rollers and filling machinery requiring corrosion resistance.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic devices.
- Semiconductor Manufacturing: Precision stages and wafer handling robots.
- Robotics: Joints and actuators in robotic arms.
