NB200XP0 Bearing Product Overview & Core Advantages
The NB200XP0 is a premium Four Point Contact Ball Bearing engineered for demanding applications requiring exceptional precision and load capacity. This thin section bearing features a single row construction with a specialized Endura-kote Plated coating, offering superior corrosion resistance and durability. Its design is optimized to handle significant combined loads, including high radial and axial forces simultaneously, making it ideal for applications where space is constrained but performance cannot be compromised. Manufactured to ABEC-1 tolerance standards, it ensures reliable operation in precision machinery.
NB200XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| NB200XP0 | Manufacturer's base model designation for this specific thin-section, four-point contact bearing series. |
| Endura-kote | Indicates a high-performance Chromium Plating coating applied to enhance surface hardness and corrosion resistance. |
| Open | Signifies the bearing has no integral seals or shields, allowing for custom lubrication schemes and minimizing friction for high-speed potential. |
| Four Point Contact | Denotes the ball-raceway contact geometry, enabling the bearing to support substantial axial loads from both directions in addition to radial loads. |
| Lubricated | The bearing is supplied with a factory-applied lubricant suitable for its specified operating temperature range. |
NB200XP0 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The Four Point Contact design and robust Chrome Steel construction enable the NB200XP0 to handle high combined loads effectively. With a radial dynamic load rating of 2731 lbf and an impressive axial static load rating of 20620 lbf, it provides a rigid and stable support structure in compact assemblies.
- Precision & Smooth Operation: The ABEC-1 precision class and Brass cage ensure smooth rotation and minimal vibration, which is critical for high-accuracy applications. The tight radial internal clearance further enhances positional accuracy.
- Durability & Corrosion Resistance: The Endura-kote Chromium Plating significantly increases surface hardness and provides excellent protection against corrosion, extending the bearing's service life in harsh environments. All components, including rings and balls, are made from high-grade Chrome Steel.
- Compact & Lightweight Design: As a thin section bearing with a cross-section of only 0.3125", it offers a high load capacity relative to its size and weight (1.5 lbs), perfect for weight-sensitive and space-constrained designs.
NB200XP0 Bearing Typical Application Areas
- Aerospace & Defense: Actuators, control mechanisms, and rotor systems.
- Robotics & Automation: Robotic joints, precision gearboxes, and rotary tables.
- Medical Equipment: CT scanners, MRI machines, and surgical robots.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Machinery: Turntables, indexing heads, and other high-precision rotary applications.
