S13003XS0 Bearing Product Overview & Core Advantages
The S13003XS0 is a metric ultra-slim four-point contact ball bearing engineered for applications demanding extreme space savings without compromising performance. Featuring a single-row design with an exceptionally thin 2.5 mm cross-section, this bearing is capable of simultaneously supporting combined radial and axial loads from any direction. Manufactured entirely from stainless steel and pre-lubricated, it offers excellent corrosion resistance and is ideal for high-precision, compact assemblies where reliability and minimal weight are critical.
S13003XS0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S13003 | Basic bearing designation indicating a 130 mm bore and ultra-slim section series. |
| X | Denotes extra-thin cross-section design. |
| S0 | Indicates a stainless steel construction for rings, balls, and cage. |
| (Open) | No seal suffix, indicating an open bearing structure for applications where seals are externally managed. |
S13003XS0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The unique raceway geometry allows the bearing to handle combined radial and axial loads from any direction with a single bearing row, simplifying assembly and reducing component count.
Ultra-Slim Cross-Section: With a width of only 2.5 mm, this bearing enables radical miniaturization and weight reduction (just 19 grams) in compact machinery and instruments.
Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel, providing excellent corrosion resistance and suitability for harsh environments or clean applications.
Precision & Rigidity: Built to ABEC-1 tolerance class with a minimal radial internal clearance (0.0000 – 0.0005"), it ensures smooth, precise operation and high system rigidity.
Pre-Lubricated & Wide Temperature Range: The bearing is pre-lubricated for immediate use and operates effectively within a temperature range of -30°C to 110°C.
S13003XS0 Bearing Typical Application Areas
The S13003XS0 is ideally suited for:
- Precision Robotics and automation arms (for joint and pivot points)
- Medical and Dental Equipment (e.g., scanners, small surgical devices)
- Aerospace Actuation Systems and control mechanisms
- Optical Positioning Systems and rotary stages
- Semiconductor Manufacturing Equipment
- Any application requiring a high-precision, thin-section bearing with multi-directional load capacity.
