SB200AR0 Bearing Product Overview & Core Advantages
The SB200AR0 is a thin section angular contact ball bearing designed for applications requiring high precision and space optimization. Manufactured from stainless steel with a brass cage, this single row bearing excels in handling combined radial and axial loads simultaneously due to its defined 30° contact angle. Its Reali-Slim cross-section provides a high load capacity within a minimal envelope, making it ideal for compact, high-performance machinery. The bearing comes pre-lubricated and is rated for a wide operating temperature range from -30°C to 110°C.
SB200AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| SB | Indicates a Stainless Steel thin section bearing from the Reali-Slim series. |
| 200 | Specifies the bore diameter in inches (20.0"). |
| A | Denotes the Angular Contact design, optimized for combined loads. |
| R0 | Specifies the radial internal clearance group (0.0000 – 0.0005"). |
| (Open) | The bearing features an open (unsealed) construction, suitable for controlled environments or custom sealing solutions. |
SB200AR0 Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The single row angular contact design, combined with an ABEC-1 tolerance class and tight dimensional tolerances, ensures high running accuracy and system rigidity, which is critical for precise positioning applications.
Superior Load Capacity: With a 30° contact angle, the SB200AR0 is engineered to support significant combined radial and axial static loads (Radial: 9610 lbf, Axial: 5900 lbf). The stainless steel construction of rings and balls provides excellent corrosion resistance without sacrificing strength.
Optimized for Space and Weight: The thin section bearing design (0.3125" width) allows for compact and lightweight assemblies, reducing overall system inertia. The brass cage contributes to smooth operation at moderate speeds.
Corrosion Resistance and Compliance: The all-stainless steel and brass components, along with ROHS compliance, make this bearing suitable for demanding environments, including those in medical, aerospace, and food processing industries.
SB200AR0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, actuator arms, and precision gearing systems.
- Aerospace and Defense: Guidance systems, radar platforms, and satellite mechanisms.
- Medical Equipment: MRI and CT scanner gantries, surgical robot joints.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Instrumentation: High-precision rotary tables and measuring devices.
