| 0 | Open design without seals or shields |
NF042XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The optimized raceway geometry allows the bearing to support substantial moment loads (8 ft-lbf rated load moment) while efficiently handling combined radial and axial loads. This design provides exceptional load distribution across the contact points.
Thin-Section Construction: With a compact cross-section (0.75" width) relative to its bore diameter (4.25"), this bearing maximizes space utilization while maintaining structural integrity, making it ideal for weight-sensitive applications.
Premium Material Composition: Constructed from chrome steel rings and balls with a brass cage, the bearing ensures dimensional stability and reliable performance. The Endura-kote chromium plating provides superior corrosion resistance compared to standard bearings.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional controls (bore and OD tolerance: -0.0008" to 0"), this bearing delivers consistent performance in precision applications.
NF042XP0 Bearing Typical Application Areas
- Aerospace & Defense: Gimbal systems, radar positioning units, and satellite mechanisms
- Robotics & Automation: Robotic joints, rotary tables, and precision positioning stages
- Medical Equipment: CT scanners, MRI systems, and surgical robot arms
