NA040XP0 Bearing Product Overview & Core Advantages
The NA040XP0 is a Four Point Contact Ball Bearing designed for exceptional performance in inch-system applications. This precision bearing features a single row construction with a unique Endura-kote chromium plating that significantly enhances corrosion resistance and durability. Engineered to simultaneously handle combined loads (radial and axial), it is ideal for applications requiring high reliability in a compact envelope. Its ABEC-1 tolerance class ensures consistent, high-quality performance for demanding industrial use.
NA040XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| NA040 | Bore size designation (4 inches) |
| XP | Indicates the bearing series and cross-section (Thin Section) |
| 0 | Specific design variant or internal specification |
Key Feature: The "Endura-kote Plated Bearings" classification denotes a superior chromium plating coating applied to the bearing components for enhanced surface properties.
NA040XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: Allows the bearing to support combined radial and axial loads from any direction with a single bearing row, simplifying assembly and saving space.
- High Rigidity & Load Capacity: The robust chrome steel construction and optimized raceway geometry provide a high static load rating (1290 lbf radial, 3220 lbf axial) for stable operation under significant loads.
- Thin Section & Lightweight: With a width of only 0.25" and a weight of 0.19 lbs, it is engineered for compact, weight-sensitive applications without sacrificing performance.
- Corrosion Resistance: The Endura-kote chromium plating offers excellent protection against corrosion, extending bearing life in challenging environments.
- Precision Performance: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance, ensuring smooth, low-vibration operation.
NA040XP0 Bearing Typical Application Areas
- Aerospace Actuation Systems (control surfaces, linkages)
- Robotics (robot arms, rotary joints)
- Medical Equipment (scanners, rotating assemblies)
- Semiconductor Manufacturing Equipment
- Precision Industrial Machinery with space constraints
