S07403XS0 Bearing Product Overview & Core Advantages
The S07403XS0 is a metric ultra-slim four-point contact ball bearing engineered for applications demanding minimal cross-section and high precision. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its defining feature is the four-point contact design, enabling it to support combined radial and axial loads from any direction simultaneously, making it an ideal, compact solution for high-accuracy rotary systems where space and weight are critical constraints.
S07403XS0 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| S | Stainless Steel construction for enhanced corrosion resistance. |
| 07 | UltraSlim bearing series designation. |
| 403 | Specific size code indicating the 74mm bore and 80mm outside diameter. |
| XS0 | Variant code, typically indicating specific internal design, radial internal clearance, and pre-lubrication. |
S07403XS0 Bearing Structural Features & Performance Benefits
- Ultra-Slim Cross-Section: With a width of just 2.5 mm, this bearing provides a maximum saving of space and weight, ideal for compact assemblies.
- Four-Point Contact Design: A single-row bearing that performs like a double-row unit, capable of handling combined loads and moment loads efficiently, simplifying design and reducing part count.
- High Precision & Rigidity: Manufactured to ABEC-1 tolerance standards with a very tight radial internal clearance, ensuring smooth, precise, and repeatable motion.
- Corrosion-Resistant Construction: All components, including rings, balls, and cage, are made from stainless steel, offering reliable performance in harsh or washdown environments.
- Pre-Lubricated & Ready-to-Use: Comes pre-lubricated for immediate installation and long-term, maintenance-free operation within its specified temperature range.
S07403XS0 Bearing Typical Application Areas
This bearing is specifically designed for high-precision, space-constrained applications, including:
- Robotics: Joints and actuators in robotic arms.
- Aerospace & Defense: Guidance systems, gimbals, and control mechanisms.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Medical Devices: Surgical robots, imaging equipment (CT/MRI scanners), and dental handpieces.
- Optical and Instrumentation Systems: Rotary stages, mirror mounts, and precision measuring devices.
