ND180XP0 Bearing Product Overview & Core Advantages
The ND180XP0 is a high-performance Four Point Contact Ball Bearing designed for applications requiring exceptional load capacity in a compact cross-section. This thin section bearing features a single row construction with an Endura-kote chromium plating, providing superior corrosion resistance and extended service life. Its defining characteristic is the ability to simultaneously support high radial loads, axial loads in both directions, and significant load moments, making it an ideal solution for precision and high-reliability applications where space and weight are critical constraints.
ND180XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| ND180 | Bearing series designation with an 18-inch bore diameter. |
| XP0 | Indicates the Endura-kote Plated coating for enhanced durability and corrosion resistance. |
| Open | No contact seals, allowing for higher speeds and easy re-lubrication. |
| Four Point Contact | The ball-raceway contact geometry enables the bearing to handle combined loads and moments efficiently. |
| ABEC-1 | Specifies the precision class governing dimensional and running accuracy tolerances. |
ND180XP0 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The Four Point Contact design and robust chrome steel construction allow the bearing to support a high radial dynamic load rating of 5226 lbf, an axial dynamic load rating of 9030 lbf, and a substantial dynamic load moment of 36268 lbf. This provides exceptional stability and rigidity under combined loading conditions.
- Compact & Lightweight Design: With a cross-section of only 0.5 inches and a weight of 3.48 lbs, this thin section bearing offers a significant strength-to-weight ratio, ideal for saving space and reducing inertia in rotational systems.
- Enhanced Durability & Corrosion Resistance: The Endura-kote chromium plating on all bearing surfaces significantly improves resistance to corrosion and wear, extending operational life even in challenging environments. The brass cage ensures smooth operation and high-speed capability.
- Precision Performance: Manufactured to ABEC-1 precision tolerances with a controlled radial internal clearance, this bearing delivers consistent, low-friction operation essential for high-precision applications.
ND180XP0 Bearing Typical Application Areas
