JHA17XL0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The single-row construction with optimized raceway geometry enables the bearing to handle combined radial and axial loads efficiently, making it suitable for complex loading conditions.
Thin Section Construction: With a minimal cross-section (0.25" width), this bearing provides significant space and weight savings while maintaining structural integrity, crucial for compact machinery design.
Sealed & Lubricated: The integrated seals protect against contamination while the factory-applied lubrication ensures consistent performance across the operating temperature range of -30°C to 110°C, reducing maintenance requirements.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with controlled radial internal clearance (0.0000 – 0.0005"), this bearing delivers reliable performance in precision applications.
JHA17XL0 Bearing Typical Application Areas
- Robotics and Automation: Joint bearings in robotic arms and precision positioning systems
- Aerospace Systems: Actuators, control mechanisms, and instrumentation where weight and space are critical
- Medical Equipment: Imaging systems, surgical robots, and diagnostic instruments requiring high precision
- Semiconductor Manufacturing: Precision stages and handling equipment in cleanroom environments
- Optical Systems: Positioning mechanisms in telescopes, cameras, and laser systems
