SF047AR0 Bearing Product Overview & Core Advantages
The SF047AR0 is a high-performance thin section angular contact ball bearing engineered for precision applications requiring exceptional rigidity and load capacity. Manufactured from corrosion-resistant stainless steel, this single-row bearing is designed to handle significant combined loads, including high thrust loads in one direction, thanks to its defined 30° contact angle. Its Reali-Slim cross-section provides a compact, lightweight solution without compromising performance, making it ideal for space-constrained, high-reliability systems demanding ABEC-1 precision.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| SF047 | Indicates the Reali-Slim series with specific inch dimensions (4.75" bore, 6.25" OD, 0.75" width). |
| A | Signifies the 30° contact angle, optimized for handling high axial loads. |
| R0 | Denotes standard radial internal clearance (0.0000 – 0.0005"). |
SF047AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides superior stiffness and enables the bearing to support high combined radial and axial loads, with a notable axial static load rating of 9260 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control on bore diameter and outside diameter, ensuring smooth operation and accurate positioning.
- Corrosion Resistance & Durability: Both rings and balls are made from stainless steel, offering excellent resistance to corrosion. The brass cage ensures stable operation under high-speed conditions.
- Optimized for Harsh Environments: The open seal type allows for custom lubrication schemes, while the stainless steel construction and wide operating temperature range (-30°C to 110°C) make it suitable for demanding applications.
SF047AR0 Bearing Typical Application Areas
- Robotics & Automation: Precision joints, rotary actuators, and manipulator arms where thin section bearings save space and weight.
- Aerospace & Defense: Guidance systems, radar platforms, and drone gimbals requiring high rigidity and corrosion resistance.
- Medical Equipment: Surgical robots, MRI scanners, and diagnostic instruments demanding ABEC-1 precision and clean operation.
- Semiconductor Manufacturing: Wafer handling robots and precision stages where combined load capacity and minimal deflection are critical.
