S11003AS0 Bearing Product Overview & Core Advantages
The S11003AS0 is a single row angular contact ball bearing from the UltraSlim Bearings series, designed for applications demanding minimal cross-section and high precision. Engineered to primarily accommodate combined loads (simultaneous radial and axial loads), its 30° contact angle provides excellent axial load capacity. Manufactured entirely from stainless steel and built to ABEC-1 precision tolerances, this bearing is ideal for compact, lightweight assemblies requiring reliable performance in corrosive environments.
S11003AS0 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| S1 | Indicates the UltraSlim bearing series with a 1-inch cross-section. |
| 1003 | Specifies the bore diameter (100 mm) and the specific bearing size variant. |
| AS0 | Denotes a 30° contact angle and an open (unsealed) design. |
S11003AS0 Bearing Structural Features & Performance Benefits
- Ultra-Thin Section & Lightweight: With a mere 2.5 mm width and a weight of only 16 grams, this bearing enables extremely compact and lightweight designs, crucial for applications where space and mass are critical constraints.
- High Precision & Rigidity: Built to ABEC-1 tolerance standards with a very low radial internal clearance (0.0000 – 0.0005"), it ensures smooth, precise rotation and minimal runout, contributing to overall system accuracy.
- Corrosion Resistance: The all-stainless steel construction (rings, balls, and cage) provides excellent resistance to corrosion, making it suitable for use in harsh environments, medical equipment, and food processing.
- Angular Contact Design: The 30° contact angle is optimized to handle significant axial loads in one direction in addition to radial loads, a key feature for applications like precision spindles.
S11003AS0 Bearing Typical Application Areas
- Precision Robotics: Used in robot joint arms and end-effectors where compact size, low weight, and high rigidity are paramount.
- Aerospace & Defense Systems: Ideal for guidance systems, gimbal mechanisms, and instrumentation due to its lightweight and corrosion-resistant properties.
- Medical & Dental Devices: Suitable for surgical handpieces, scanners, and other precision medical instruments requiring smooth, reliable motion.
- Optical & Instrumentation Systems: Applied in rotary stages, encoders, and measuring devices where high precision and minimal cross-section are required.
