SA025AR0 Bearing Product Overview & Core Advantages
The SA025AR0 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 bearing is specifically designed to handle significant combined loads, supporting both radial and axial forces simultaneously. Its Reali-Slim cross-section provides a compact, lightweight solution without sacrificing performance, making it ideal for high-rigidity applications where weight and space are critical constraints. The bearing comes pre-lubricated and is rated for a wide operating temperature range, ensuring reliable performance in demanding environments.
SA025AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SA025 | Series & Bore Size (2.5") | Identifies the Reali-Slim series with a 2.5-inch bore diameter. |
| A | Angular Contact Design | Specifies the 30° contact angle for handling combined loads. |
| R0 | Radial Internal Clearance & Open Design | Indicates standard radial internal clearance and an open (unsealed) construction. |
SA025AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The Reali-Slim construction (0.25" width) minimizes weight and space requirements while maintaining structural integrity, crucial for compact machinery and aerospace applications.
High Load Capacity: The 30° contact angle and single-row design are optimized to support substantial combined radial and axial loads (Radial Dynamic: 459 lbf, Axial Static: 1100 lbf), providing excellent performance under complex loading conditions.
Precision & Rigidity: Manufactured to ABEC-1 tolerance standards with tight dimensional controls, this bearing ensures smooth operation and high positional accuracy. The stainless steel rings and brass cage contribute to consistent performance and corrosion resistance.
Material & Environmental Suitability: Constructed entirely from stainless steel with a brass cage, the bearing offers good corrosion resistance and is suitable for a temperature range of -30°C to 110°C.
SA025AR0 Bearing Typical Application Areas
The SA025AR0 is ideally suited for precision applications where space, weight, and accuracy are paramount. Key industries and equipment include:
- Robotics and Automation: Robot arm joints, precision gearing systems.
- Aerospace & Defense: Guidance systems, actuator mechanisms, satellite components.
- Medical Equipment: Surgical robots, imaging devices, diagnostic instruments.
