SB030AR0 Bearing Product Overview & Core Advantages
The SB030AR0 is a thin section angular contact ball bearing engineered for applications demanding high precision and space optimization. Manufactured from stainless steel with a 30° contact angle, this single row bearing is specifically designed to handle significant combined loads, including high thrust loads in one direction alongside radial loads. Its Reali-Slim cross-section provides a superior strength-to-size ratio, making it ideal for compact, weight-sensitive designs requiring high rigidity and reliable performance within a specified temperature range.
SB030AR0 Bearing Model Code Explained, Specifications & Naming Convention
The model number SB030AR0 can be broken down to reveal its key technical specifications:
- SB: Indicates a Stainless Steel thin section bearing.
- 030: Represents the nominal bore size in inches (3").
- A: Signifies the Angular Contact design with a 30° contact angle.
- R0: Denotes an Open (unsealed) construction and standard internal clearance.
SB030AR0 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design with a 30° contact angle and stainless steel construction enables the bearing to support high radial dynamic load ratings of 734 lbf and exceptional axial static load ratings of 1750 lbf, making it suitable for applications with significant moment loads.
- Precision Engineering: Built to ABEC-1 tolerance standards, this bearing ensures consistent running accuracy and smooth operation, which is critical for precision mechanisms.
- Corrosion Resistance: The use of stainless steel for both rings and balls provides excellent corrosion resistance, enhancing the bearing's longevity in harsh environments.
- Optimized Cage Design: The brass cage ensures stable ball guidance and reliable performance, contributing to smooth operation at moderate speeds.
SB030AR0 Bearing Typical Application Areas
This bearing is ideally suited for applications where space, weight, and precision are critical. Common uses include:
- Robotics and Automation: Joint and arm assemblies requiring high moment load capacity.
- Aerospace and Defense: Gimbals, control mechanisms, and instrumentation.
- Medical Equipment: Scanners, surgical robots, and precision positioning stages.
- Semiconductor Manufacturing: Wafer handling and precision positioning equipment.
