JA047XP0 Bearing Product Overview & Core Advantages
The JA047XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Sealed Bearings series, designed for applications demanding compact cross-sections and high load capacity. This thin section bearing excels at simultaneously handling combined radial and axial loads from any direction, making it an ideal solution for space-constrained, high-rigidity systems. Its sealed construction and pre-lubrication ensure long-term reliability and low maintenance operation in demanding environments.
JA047XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| JA047 | Indicates the specific bearing series and size designation within the Reali-Slim family. |
| XP0 | Signifies a sealed bearing variant, offering protection against contamination. |
JA047XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The single-row construction with a four point contact raceway enables the bearing to support significant combined radial and moment loads, as well as axial loads in both directions, providing exceptional versatility in a compact package.
- Thin Section & High Rigidity: With a consistent cross-section (0.25" width) across a large bore (4.75"), this bearing maximizes structural stability and rigidity while minimizing weight and space requirements.
- Sealed & Lubricated for Life: The integrated seals retain the factory-applied lubricant, effectively excluding contaminants. This creates a maintenance-free solution ideal for applications where re-lubrication is difficult.
- Precision & Material Quality: Manufactured to ABEC-1 precision tolerances from Chrome Steel rings and balls with a Brass cage, the bearing ensures smooth operation, consistent performance, and high durability.
JA047XP0 Bearing Typical Application Areas
This bearing is engineered for use in precision machinery and equipment where a large, hollow shaft is required and space is at a premium. Key applications include:
- Robotics (Robotic arms and joints)
- Aerospace & Defense (Gimbals, radar platforms, control systems)
- Medical Equipment (CT scanners, MRI machines)
- Semiconductor Manufacturing (Wafer handling robots, precision stages)
- Industrial Automation (Rotary tables, indexing heads)
