SA030AR0 Bearing Product Overview & Core Advantages
The SA030AR0 is a thin-section angular contact ball bearing engineered for applications requiring high precision and space optimization. Constructed from stainless steel with a brass cage, this single-row bearing is designed to handle significant combined loads, including high axial loads in one direction due to its 30° contact angle. Its ABEC-1 precision class and corrosion-resistant materials make it ideal for demanding environments where reliability and dimensional stability are critical.
SA030AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SA | Stainless Steel construction for enhanced corrosion resistance |
| 030 | 30° contact angle optimized for high axial load capacity |
| A | Angular Contact design for combined load handling |
| R0 | Standard radial internal clearance (0.0000 – 0.0005") |
SA030AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a consistent cross-section (3" bore, 3.5" OD, 0.25" width), this bearing enables compact, lightweight assemblies without sacrificing performance, making it perfect for space-constrained applications.
High Load Capacity: The 30° contact angle and optimized raceway geometry provide exceptional axial static load capacity (1230 lbf) and radial dynamic load rating (507 lbf), enabling reliable operation under combined loading conditions.
Precision Performance: Manufactured to ABEC-1 tolerance standards with tight dimensional controls, this bearing ensures smooth operation and minimal runout for high-precision applications.
Corrosion Resistance: The all-stainless steel construction (rings and balls) provides excellent protection against corrosion, while the brass cage ensures reliable operation across the specified temperature range (-30°C to 110°C).
SA030AR0 Bearing Typical Application Areas
- Robotics and Automation: Joint bearings, rotary actuators, and precision positioning systems
- Aerospace and Defense: Guidance systems, control mechanisms, and instrumentation
- Medical Equipment: Surgical robots, imaging devices, and diagnostic instruments
- Semiconductor Manufacturing: Wafer handling equipment and precision stages
