SG090AR0 Bearing Product Overview & Core Advantages
The SG090AR0 is a stainless steel thin-section angular contact ball bearing designed for applications requiring high precision and corrosion resistance. This single-row bearing excels in handling combined radial and axial loads simultaneously, thanks to its optimized 30° contact angle. Manufactured to ABEC-1 precision standards, it delivers reliable performance in demanding environments while maintaining an ultra-slim cross-section profile (1" width) relative to its 9" bore diameter. The stainless steel construction ensures excellent corrosion resistance and dimensional stability across a wide temperature range.

SG090AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The compact 1" width provides significant space and weight savings while maintaining high load capacity, making it ideal for applications with strict envelope constraints.
Angular Contact Performance: The 30° contact angle enables superior axial load capacity (21,640 lbf static) while maintaining excellent radial load handling (9,073 lbf dynamic). This makes the bearing particularly effective for combined loading scenarios.
Premium Material Construction: Stainless steel rings and balls provide exceptional corrosion resistance and dimensional stability, while the brass cage ensures smooth operation and reliable performance across the specified temperature range (-30°C to 110°C).
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore tolerance: -0.0012" to 0"), ensuring consistent performance and easy installation in precision applications.
SG090AR0 Bearing Typical Application Areas
- Aerospace & Defense Systems: Guidance systems, radar positioning equipment, and aircraft control mechanisms
- Medical Equipment: CT scanners, MRI machines, and surgical robotics requiring corrosion-resistant precision bearings
- Semiconductor Manufacturing: Wafer handling robots and precision positioning stages
- Food Processing Machinery: Equipment requiring stainless steel components for hygiene and corrosion resistance
