JU055XPOK Bearing Product Overview & Core Advantages
The JU055XPOK is a high-performance thin section sealed bearing designed for applications requiring exceptional precision and space optimization. As part of the Reali-Slim series, this single row ball bearing features a Four Point Contact design, enabling it to support significant combined radial and axial loads simultaneously. Its inch-series construction with a large 5.5" bore and slim 0.5" cross-section makes it ideal for compact, high-rigidity systems in robotics, aerospace, and medical equipment where weight and space are critical constraints.
JU055XPOK Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| JU055XPOK | Reali-Slim sealed bearing series with specific dimensional coding | Identifies the thin-section, large bore bearing family |
| Sealed | Integrated sealing system | Contaminant protection and lubricant retention |
| Four Point Contact | Ball-raceway contact geometry | Superior combined load capacity in both radial and axial directions |
JU055XPOK Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique ball-to-raceway contact geometry provides exceptional load moment capacity (Dynamic: 3717 lbf, Static: 8300 lbf), enabling the bearing to handle substantial overturning moments while maintaining precise operation.
Thin Section Construction: With only 0.375" radial cross-section (calculated from bore and OD), this bearing delivers maximum performance in minimal space, reducing system weight and enabling compact bearing arrangements.
Premium Material Selection: Chrome steel rings and balls combined with a brass cage provide excellent wear resistance and dimensional stability, while the integrated seals protect against contamination in demanding environments.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore/OD tolerance: -0.0010"– 0"), ensuring consistent performance and easy installation in precision applications.
JU055XPOK Bearing Typical Application Areas
- Robotics and Automation: Robotic joints, rotary actuators, and precision positioning systems
- Aerospace and Defense: Gimbal systems, radar platforms, and satellite mechanisms
- Medical Equipment: CT scanners, surgical robots, and diagnostic imaging systems
- Semiconductor Manufacturing: Wafer handling robots and precision stages
