ND140XP0 Bearing Product Overview & Core Advantages
The ND140XP0 is a four-point contact ball bearing engineered for exceptional performance in demanding applications. This thin section bearing features a single row design with a chromium plating (Endura-kote) coating, offering superior corrosion resistance and extended service life. Its primary advantage lies in its ability to simultaneously support combined loads, including high radial loads, axial loads in both directions, and significant moment loads, making it an ideal solution for compact, high-precision assemblies requiring maximum load capacity within minimal cross-sections.
ND140XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| ND140XP0 | Manufacturer's specific model designation for this bearing series and size. |
| Endura-kote | Indicates a chromium plating coating applied to the bearing rings for enhanced corrosion resistance and durability. |
| Open | Signifies the bearing has no integral seals or shields, allowing for custom lubrication schemes and maximum speed capability. |
| Four Point Contact | Describes the raceway geometry that allows the bearing to support moment loads and bidirectional axial loads with a single bearing row. |
| Lubricated | The bearing is supplied with a factory-applied lubricant suitable for initial operation. |
| ABEC-1 | Specifies the precision class of the bearing, ensuring controlled running accuracy and performance. |
ND140XP0 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its optimized construction. The four-point contact design is the cornerstone of its capability, enabling it to handle substantial combined loads and moment loads (rated at 24 ft-lbf) with a compact, single row profile. This makes it exceptionally space-efficient. The use of chrome steel for both rings and balls, combined with a brass cage, ensures high strength, dimensional stability, and reliable operation. The Endura-kote chromium plating significantly boosts corrosion resistance, allowing reliable performance in challenging environments. With a tight radial internal clearance (0.0000 – 0.0005") and ABEC-1 precision tolerances, it delivers smooth, precise rotation essential for high-accuracy applications.
ND140XP0 Bearing Typical Application Areas
The ND140XP0 is ideally suited for applications where high load capacity and a slim cross-section are critical. Its robust moment load and axial load capacity make it a prime choice for:
- Robotics (especially rotary joints and actuators)
- Aerospace and Defense systems (gimbals, control mechanisms)
- Semiconductor Manufacturing Equipment
- Medical Imaging and Surgical Robotics
- Industrial Turntables and Indexing Tables
- Radar and Communication Antenna Positioning Systems
