SD200AR0 Bearing Product Overview & Core Advantages
The SD200AR0 is a thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. As part of the Reali-Slim® series, this stainless steel bearing offers a superior strength-to-cross-section ratio, making it ideal for compact designs. Its single-row construction with a 30° contact angle is specifically designed to handle combined loads, efficiently supporting significant radial and axial forces simultaneously. The bearing comes pre-lubricated and is built to ABEC-1 precision tolerances, ensuring reliable performance in demanding environments.
SD200AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD200 | Indicates the bearing series (Reali-Slim®) and size designation (200). |
| A | Signifies the 30° contact angle, optimized for handling high axial loads. |
| R0 | Designates a standard radial internal clearance and an open (unsealed) construction. |
SD200AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design, combined with a brass cage and a 30° contact angle, provides high rigidity and enables the bearing to support substantial combined radial and axial loads, with a static load moment rating of 46,740 lbf.
- Corrosion Resistance & Lightweight: Constructed entirely from stainless steel (rings and balls), the bearing offers excellent corrosion resistance. Its thin-section design results in a low weight of just 3.65 lbs for a 20-inch bore, reducing rotational inertia.
- Precision Performance: Manufactured to ABEC-1 tolerance classes with tight bore and OD tolerances, it ensures smooth, precise operation and consistent performance.
- Pre-lubricated for Immediate Use: The bearing is supplied lubricated, ready for installation and initial operation, simplifying the assembly process.
SD200AR0 Bearing Typical Application Areas
This bearing is ideally suited for applications where a large bore, a slim cross-section, and high load capacity are critical. Key industries and equipment include:
- Aerospace & Defense: Gimbal systems, radar platforms, and rotary actuators.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Medical Equipment: CT scanners, MRI machines, and robotic surgical arms.
- Robotics: Robotic joints and precision rotary axes.
- Optical Instrumentation: Telescope mounts and rotary positioning stages.
