S15003AS0 Bearing Product Overview & Core Advantages
The S15003AS0 is a metric ultra-slim single row angular contact ball bearing engineered for applications demanding minimal cross-section and high precision. This bearing excels in handling combined loads—simultaneously supporting significant radial loads and thrust loads in one direction due to its 30° contact angle. Manufactured entirely from stainless steel and compliant with ABEC-1 precision tolerances, it is ideal for compact, high-reliability mechanisms where space and weight are critical constraints.
S15003AS0 Bearing Model Code Explained, Specifications & Naming Convention
The model number S15003AS0 can be broken down as follows:
- S15: Indicates a thin-section bearing series with a cross-section of 3/16" (approximately 4.7625mm).
- 003: Specifies a bore diameter of 3 inches (approximately 76.2mm). Note: The provided specification of 150mm bore suggests a potential model/data discrepancy; please verify the exact product code with engineering documentation.
- A: Denotes a 30° contact angle, optimized for high thrust capacity.
- S0: Signifies a standard radial internal clearance and open (unsealed) construction.
S15003AS0 Bearing Structural Features & Performance Benefits
- Ultra-Slim Design & High Rigidity: With a remarkably small width of 2.5 mm, this bearing enables extremely compact assemblies. The single-row angular contact design provides high axial and moment stiffness in a minimal envelope.
- Superior Load Capacity: The 30° contact angle is engineered to handle high combined loads, offering a radial dynamic load rating of 225 lbf and a static load moment of 160 lbf.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a tight radial internal clearance (0.0000 – 0.0005 inches), it ensures smooth, precise, and repeatable operation.
- Corrosion Resistance & Lightweight: Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. The ultra-slim profile contributes to a very low weight of 22 grams.
S15003AS0 Bearing Typical Application Areas
This bearing is specifically designed for compact, high-precision systems, including:
- Robotics: Rotary joints and actuator arms where space and weight are premium.
- Aerospace & Defense: Guidance systems, gimbals, and control mechanisms.
- Medical Equipment: Surgical robots, precision scanners, and diagnostic devices.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical Instrumentation: Rotary stages in imaging and alignment systems.
