JU047XP0 Bearing Product Overview & Core Advantages
The JU047XP0 is a high-performance thin-section sealed bearing designed for applications requiring exceptional space efficiency and precision. As a Four Point Contact Ball Bearing, it excels at simultaneously handling combined radial and axial loads from any direction. Its inch-sized dimensions (4.75" bore, 5.5" OD) with a remarkably slim 0.5" cross-section make it ideal for compact, weight-sensitive assemblies. Manufactured to ABEC-1 precision and pre-lubricated, this bearing delivers reliable operation and long service life in demanding environments.

| Code Segment | Technical Meaning |
|---|---|
| JU047 | Reali-Slim® series bearing designation with specific inch dimensions (4.75" bore) |
| XP0 | Indicates sealed construction and specific internal configuration for Four Point Contact |
JU047XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The optimized raceway geometry enables a single bearing row to support combined radial and axial loads in both directions, simplifying assembly design and reducing component count.
- Thin-Section Construction: With a consistent 0.5" cross-section across all sizes, this bearing provides maximum space savings and weight reduction while maintaining structural integrity.
- High-Precision Components: Manufactured from Chrome Steel with a Brass cage, the bearing ensures smooth operation, excellent wear resistance, and consistent performance under dynamic and static load conditions.
- Sealed & Lubricated: Integrated seals protect against contamination while factory-applied lubricant ensures immediate operation and extended maintenance intervals across a wide temperature range (-30°C to 110°C).
- Precision Tolerances: ABEC-1 tolerance class and controlled radial internal clearance (0.0000 – 0.0005") guarantee predictable performance and smooth rotation in precision applications.
JU047XP0 Bearing Typical Application Areas
- Robotics & Automation: Rotary joints, robotic arms, and precision positioning systems requiring slim cross-sections and multi-directional load capacity.
- Aerospace & Defense: Radar systems, gimbal mechanisms, and flight control surfaces where weight savings and reliability are critical.
- Medical Equipment: CT scanners, surgical robots, and imaging devices demanding high precision and smooth motion in compact spaces.
- Industrial Machinery:
- Rotary tables and indexing heads
- Precision gearboxes and speed reducers
- Material handling equipment
