SC047AR0 Bearing Product Overview & Core Advantages
The SC047AR0 is a thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. Constructed entirely from stainless steel with a brass cage, it offers excellent corrosion resistance. Its 30° contact angle is specifically designed to support combined loads, effectively handling both radial and significant axial thrust in one direction. This single-row bearing is ideal for compact assemblies requiring high reliability and smooth operation under moderate speeds, making it a superior choice for precision machinery.
SC047AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SC | Indicates the Reali-Slim thin-section bearing series. |
| 047 | Specifies the bore diameter of 4.75 inches. |
| A | Denotes the 30° contact angle, optimized for axial load capacity. |
| R0 | Signifies a standard radial internal clearance and open (unsealed) construction. |
SC047AR0 Bearing Structural Features & Performance Benefits
- Thin-Section Design & High Rigidity: The cross-section is precisely engineered to be thin (0.375" width) while maintaining structural integrity, enabling significant space and weight savings in complex assemblies without sacrificing performance.
- Superior Load Capacity: The 30° contact angle and optimized raceway geometry allow this bearing to support high axial static loads (3100 lbf) in addition to its radial dynamic load rating (1274 lbf), making it highly effective for combined load conditions.
- Precision & Smooth Operation: Manufactured to ABEC-1 tolerance standards with a tight radial internal clearance, it ensures precise running accuracy and low vibration. The brass cage promotes stable operation and is suitable for a range of rotational speeds.
- Corrosion Resistance & Durability: The use of stainless steel for both rings and balls provides excellent resistance to corrosion, extending service life in challenging environments and complying with RoHS standards.
SC047AR0 Bearing Typical Application Areas
This bearing is ideally suited for applications where a large diameter is required in a confined space. Key industries and equipment include:
- Aerospace & Defense: Gimbals, rotor heads, and control mechanisms.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic devices.
- Robotics: Joint and actuator bearings in robotic arms.
- Optical Instrumentation: Rotary stages for telescopes and surveying equipment.
