SD047CP0 Bearing Product Overview & Core Advantages
The SD047CP0 is a Reali-Slim Stainless Steel single row ball bearing designed for applications demanding compact cross-sections and corrosion resistance. This thin section bearing features a large 4.75" bore within a minimal 0.5" width, offering a high load capacity relative to its size. Its stainless steel construction ensures reliable performance in harsh environments, while its ABEC-1 precision and optimized radial dynamic load rating of 1892 lbf make it a robust and precise solution for space-constrained, high-performance machinery.
SD047CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD047 | Indicates the specific bearing size series with a 4.75" bore and 5.75" outside diameter. |
| C | Specifies the radial internal clearance group (C3 equivalent in this context, corresponding to 0.0000 – 0.0005"). |
| P0 | Denotes the standard tolerance class, equivalent to ABEC-1 precision. |
| Open / Lubricated | The bearing is supplied open (unsealed) and is pre-lubricated for immediate operation. |
SD047CP0 Bearing Structural Features & Performance Benefits
- Superior Space Efficiency: The thin section design (0.5" width) provides a large diameter-to-width ratio, enabling compact and lightweight assemblies without sacrificing bore size.
- Corrosion Resistance & Durability: Constructed entirely from stainless steel rings and balls with a brass cage, this bearing is ideal for applications exposed to moisture, chemicals, or requiring washdown.
- High Load Capacity: Engineered to handle significant radial loads (1892 lbf dynamic, 3530 lbf static) despite its slim profile, ensuring long service life under demanding conditions.
- Stable Operation & Precision: The ABEC-1 tolerance class and controlled radial internal clearance contribute to smooth, low-vibration running and precise rotational accuracy.
- Broad Temperature Range: Suitable for operating temperatures from -30°C to 110°C, accommodating a wide range of industrial environments.
SD047CP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where a large, precise shaft must be supported within a very limited axial space. Key industries and equipment include:
- Robotics: Joint and actuator bearings in robotic arms.
- Aerospace & Defense: Gimbals, control mechanisms, and instrumentation.
- Medical Equipment: Scanners, centrifuges, and surgical robots.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Imaging Systems: Rotary stages for cameras and sensors.
