JA035XPOK Bearing Product Overview & Core Advantages
The JA035XPOK is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Sealed Bearings series, designed with an ultra-thin cross-section. Engineered for applications demanding compact design and high load capacity, this bearing excels at simultaneously handling combined radial loads and axial loads from any direction. Its sealed construction, pre-lubrication, and ABEC-1 precision make it an ideal solution for high-reliability, space-constrained systems requiring minimal maintenance.
JA035XPOK Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| Reali-Slim | Ultra-Thin Section Bearing Series | Saves critical space and weight in compact designs. |
| Sealed | Integrated Seals | Provides contamination protection for extended bearing service life and reduced maintenance. |
| Four Point Contact | Single Row Design Supporting Combined Loads | Enables a single bearing to replace a more complex bearing arrangement, simplifying design. |
JA035XPOK Bearing Structural Features & Performance Benefits
- High Load Capacity in a Compact Form: The Four Point Contact design and robust Chrome Steel construction allow this thin-section bearing to support significant combined loads (Radial Dynamic: 701 lbf, Axial Dynamic: 1110 lbf) despite its minimal bearing width of only 0.25".
- Superior Rigidity and Moment Load Capacity: The optimized geometry provides excellent resistance to moment loads, with a rated Dynamic Load Moment of 986 ft-lbf, ensuring stable performance under complex loading conditions.
- Long-Term, Maintenance-Free Operation: The integral seals effectively exclude contaminants, while the factory-applied lubrication is suitable for a temperature range of -30°C to 110°C, ensuring consistent performance and long bearing service life without re-lubrication.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a controlled radial internal clearance, this bearing delivers smooth, quiet, and precise running essential for high-performance applications.
JA035XPOK Bearing Typical Application Areas
This bearing is ideally suited for compact machinery and precision systems where space and weight are at a premium. Key industries and equipment include:
- Robotics: Joint and actuator bearings in robotic arms and precision gearboxes.
- Aerospace & Defense: Actuation systems, radar platforms, and guidance systems.
- Medical Equipment: Scanning, imaging, and surgical robot components.
- Semiconductor Manufacturing: Precision stages and wafer handling robots.
- Industrial Automation: Rotary tables, indexing heads, and CNC rotary axes.
