SD047AR0 Bearing Product Overview & Core Advantages
The SD047AR0 is a precision thin-section angular contact ball bearing engineered for applications demanding high accuracy and space-saving designs. Manufactured from stainless steel with a brass cage, it offers excellent corrosion resistance. Its single-row angular contact design is optimized to support combined loads, efficiently handling both radial and substantial axial thrust loads in one direction. With an ABEC-1 tolerance class and a defined 30° contact angle, this bearing provides reliable performance in high-precision assemblies where rigidity and compactness are critical.
SD047AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD047 | Indicates the bearing series and size prefix for a thin-section bearing. |
| A | Signifies the 30° contact angle, which is optimal for supporting high axial loads. |
| R0 | Specifies the radial internal clearance group (0.0000 – 0.0005"). |
SD047AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact construction with a 30° contact angle provides high axial and radial stiffness, enabling it to handle significant combined loads (Radial Static: 4150 lbf, Axial Static: 4720 lbf).
- Precision Performance: Built to ABEC-1 tolerance standards with a tight radial internal clearance, ensuring smooth, precise operation and minimal runout for high-accuracy applications.
- Corrosion Resistance & Durability: The use of stainless steel for rings and balls, combined with a brass cage, provides excellent resistance to corrosion and ensures reliable performance in harsh environments.
- Compact & Lightweight Design: As part of the Reali-Slim series, it features a thin cross-section (Width: 0.5") and low weight (0.93 lbs), enabling compact machine designs without sacrificing performance.
SD047AR0 Bearing Typical Application Areas
This bearing is ideally suited for:
- Precision Robotics: Rotary joints and arm assemblies requiring high moment load capacity (11970 lbf).
- Aerospace & Defense Systems: Gimbals, control mechanisms, and sensor platforms where corrosion resistance and reliability are paramount.
- Medical Equipment: CT scanners, surgical robots, and imaging devices demanding high precision and smooth motion.
- Semiconductor Manufacturing: Wafer handling robots and precision stages that operate in cleanroom environments.
