JB047XP0 Bearing Product Overview & Core Advantages
The JB047XP0 is a high-performance thin section sealed bearing designed for applications requiring exceptional precision and compact design. As part of the Reali-Slim Sealed Bearings series, this single row, four point contact ball bearing excels at simultaneously handling combined radial and axial loads from any direction. Its inch-dimensioned, lightweight construction (0.35 lbs) provides a superior strength-to-weight ratio, making it ideal for space-constrained, high-rigidity applications demanding ABEC-1 precision and reliable, long-term performance.
JB047XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| JB047 | Bearing series designation for Reali-Slim sealed type with specific bore diameter (4.75") |
| XP0 | Variant code indicating specific internal configuration and performance characteristics |
| Sealed | Integrated sealing for contamination protection and lubricant retention |
| Four Point Contact | Ball-raceway contact geometry enabling combined load capacity in all directions |
JB047XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique ball-to-raceway contact geometry enables this bearing to handle significant combined radial and axial loads from any direction, providing versatile load-carrying capability in a single row configuration.
Thin Section Construction: With a cross-section of only 0.3125" between 4.75" bore and 5.375" outside diameter, this design maximizes space utilization while maintaining structural integrity, offering exceptional stiffness-to-weight ratio.
Precision Engineering: Manufactured to ABEC-1 tolerance class with minimal radial internal clearance (0.0000 – 0.0005"), ensuring smooth operation and precise positioning accuracy.
Integrated Sealing & Lubrication: The sealed construction provides effective contamination exclusion and lubricant retention, supporting maintenance-free operation within the specified temperature range (-30°C to 110°C).
Enhanced Load Capacity: The combination of chrome steel rings, chrome steel balls, and brass cage delivers robust performance with dynamic load ratings of 1193 lbf (radial) and 1900 lbf (axial).
