SA090AR0 Bearing Product Overview & Core Advantages
The SA090AR0 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, it excels in handling combined radial and axial loads simultaneously. Its compact cross-section and 30° contact angle provide exceptional rigidity and accuracy, making it ideal for high-performance machinery where weight and space are critical constraints. The bearing is pre-lubricated for immediate use and operates effectively across a wide temperature range.

SA090AR0 Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The single-row angular contact design with a precise 30° contact angle provides superior axial and radial stiffness, ensuring stable performance under combined loads. Manufactured to ABEC-1 tolerance standards, it guarantees consistent running accuracy.
Exceptional Load Capacity: Engineered to support significant radial dynamic loads (954 lbf) and axial static loads (2470 lbf), making it suitable for applications with demanding load requirements.
Corrosion Resistance & Durability: Constructed entirely from stainless steel (rings and balls) with a brass cage, this bearing offers excellent resistance to corrosion and is ideal for harsh environments.
Space-Saving Design: As part of the Reali-Slim series, it features an ultra-thin cross-section (0.25" width), enabling compact and lightweight assemblies without sacrificing performance.
SA090AR0 Bearing Typical Application Areas
- Aerospace & Defense: Guidance systems, rotor assemblies, and actuation mechanisms.
- Semiconductor Manufacturing: Precision stages, wafer handling robots, and inspection equipment.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic instruments requiring high hygiene and reliability.
- Robotics: Joint actuators and precision gearboxes where compact size and high rigidity are critical.
- Optical Instrumentation: Rotary stages and positioning systems demanding high accuracy and minimal deflection.
