S07403AS0 Bearing Product Overview & Core Advantages
The S07403AS0 is a metric ultra-slim single row angular contact ball bearing engineered for applications demanding minimal cross-section and high precision. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its primary advantage lies in its ability to support combined loads, efficiently handling both radial and axial loads in one direction due to its specified 30° contact angle. With an ABEC-1 tolerance class, this bearing is designed for high reliability in compact, weight-sensitive assemblies where space is at a premium.
S07403AS0 Bearing Model Code Explained, Specifications & Naming Convention
The model number S07403AS0 can be broken down as follows:
- S: Stainless Steel construction
- 07: Series designation for UltraSlim bearings
- 403: Specific size code within the series
- A: Denotes a 30° contact angle
- S0: Indicates a standard radial internal clearance and open (non-shielded) seal type
S07403AS0 Bearing Structural Features & Performance Benefits
- Ultra-Slim Design & High Rigidity: With a remarkably thin 2.5 mm cross-section, this bearing maximizes space utilization while the single-row angular contact design provides high rigidity against moment loads (static load moment: 235 lbf).
- Precision & Load Capacity: Manufactured to ABEC-1 precision tolerances, it ensures smooth, reliable operation. The 30° contact angle is optimized to handle significant combined radial and axial loads (dynamic: 142 lbf, static: 180 lbf).
- Corrosion Resistance & Temperature Stability: The all-stainless steel construction (rings, balls, cage) ensures long-term performance in harsh environments, with an operational temperature range of -30°C to 110°C.
- Pre-Lubricated: The bearing comes pre-lubricated for immediate use, reducing initial assembly time and ensuring optimal performance from the first rotation.
S07403AS0 Bearing Typical Application Areas
This bearing is ideally suited for compact, high-precision mechanisms including:
- Precision instruments and optical encoders
- Robotic arms and miniature gearboxes
- Aerospace and defense actuation systems
- Medical devices and laboratory equipment
- Semiconductor manufacturing equipment
