S08003AS0 Bearing Product Overview & Core Advantages
The S08003AS0 is a metric ultra-slim angular contact ball bearing engineered for precision applications requiring minimal cross-section and high performance. This single-row bearing excels in handling combined radial and axial loads simultaneously, thanks to its defined 30° contact angle. Constructed entirely from stainless steel and pre-lubricated, it offers excellent corrosion resistance and is designed for compact assemblies where space and weight are critical constraints, without compromising on ABEC-1 precision.
S08003AS0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S08003 | Indicates the ultra-slim series with an 80mm bore diameter. |
| A | Signifies Angular Contact design with a 30° contact angle. |
| S | Denotes the bearing rings and balls are made of Stainless Steel. |
| 0 | Specifies an Open (non-shielded/non-sealed) construction. |
S08003AS0 Bearing Structural Features & Performance Benefits
- Ultra-Slim Design: With a minimal cross-section of just 2.5mm width, this bearing enables highly compact and lightweight machinery designs, ideal for applications with severe space limitations.
- Angular Contact & Load Capacity: The 30° contact angle is optimized to support significant combined radial and axial loads. It features a radial dynamic load rating of 149 lbf and a static load moment of 225 lbf, providing reliable performance under complex loading conditions.
- Precision & Stability: Manufactured to ABEC-1 tolerance class with a controlled radial internal clearance, it ensures smooth, low-vibration operation and consistent rotational accuracy.
- Corrosion Resistance & Lubrication: The all-stainless steel construction (rings, balls, cage) provides excellent resistance to corrosion. The bearing is pre-lubricated for immediate use and operates effectively within a temperature range of -30°C to 110°C.
S08003AS0 Bearing Typical Application Areas
This bearing is ideally suited for:
- Precision Robotics and automation arms (for joint and actuator mechanisms)
- Medical and Dental Equipment (e.g., small motors in handpieces, scanners)
- Optical Positioning Systems and rotary encoders
- Aerospace Instrumentation and guidance systems requiring lightweight components
- High-Speed Small Spindles in PCB drilling and engraving machines
