ND047XP0 Bearing Product Overview & Core Advantages
The ND047XP0 is a thin section bearing designed for applications requiring high precision and compact design. As a Four Point Contact Ball Bearing with Endura-kote Plating, it delivers exceptional performance in handling combined loads including radial, axial, and moment loads simultaneously. Its inch-dimension configuration (4.75" bore × 5.75" OD × 0.5" width) provides optimal space utilization while maintaining high rigidity and smooth operation. The chromium plating enhances corrosion resistance, making it suitable for demanding industrial environments.
ND047XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| ND047 | Bore diameter designation (4.75") | Precise inch-size compatibility |
| XP0 | Crossed roller bearing equivalent in four-point contact design | Superior moment load capacity and stiffness |
| Endura-kote | Chromium plating coating | Enhanced corrosion resistance and durability |
| Open | No seal/closure | Allows for custom lubrication schemes |
Structural Features & Performance Advantages
Four Point Contact Design: Enables the bearing to handle combined radial, axial, and moment loads simultaneously, replacing multiple bearing arrangements with a single compact unit.
Thin Section Construction: The 0.5" width provides significant space and weight savings while maintaining high rigidity and precision.
Premium Materials: Chrome steel rings and balls with brass cage ensure high durability and smooth operation under various load conditions.
Precision Engineering: ABEC-1 tolerance class with controlled radial internal clearance (0.0000 – 0.0005") guarantees consistent performance and accurate positioning.
Surface Treatment: Chromium plating (Endura-kote) provides excellent corrosion protection, extending service life in harsh environments.
ND047XP0 Bearing Typical Application Areas
Robotics & Automation: Robot arms, rotary joints, and precision positioning systems requiring high moment stiffness.
Aerospace & Defense: Radar systems, gimbal mechanisms, and satellite positioning equipment.
Medical Equipment: CT scanners, MRI machines, and surgical robot joints demanding precision motion control.
Industrial Machinery: Rotary tables, indexing heads, and precision gearboxes where space optimization is critical.
Semiconductor Manufacturing: Wafer handling equipment and precision stages requiring cleanroom compatibility and minimal particle generation.
