NAA10XL0 Bearing Product Overview & Core Advantages
The NAA10XL0 is a high-performance **thin section bearing** designed for applications requiring exceptional precision and space optimization. As a **Four Point Contact Ball Bearing**, it excels at simultaneously handling **combined radial and axial loads** from any direction. Featuring a **single row** construction with **Endura-kote Plating**, this bearing offers superior corrosion resistance and extended service life in demanding environments. Its compact design, with a 1" bore and 0.1875" width, makes it ideal for high-accuracy mechanisms where weight and space are critical constraints.
NAA10XL0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| NAA10XL0 | Series designation for thin section four-point contact bearings | Identifies optimized geometry for space-constrained applications |
| Endura-kote | Chromium plating surface treatment | Enhanced corrosion resistance and durability |
| Open | No seals or shields | Maximum speed capability and custom lubrication options |
| Four Point Contact | Ball-raceway contact geometry | Superior **load capacity** in all directions |
NAA10XL0 Bearing Structural Features & Performance Benefits
Optimized Contact Geometry: The four-point contact design enables the bearing to support significant combined loads while maintaining minimal cross-section. This configuration provides exceptional moment load capacity (110 ft-lbf dynamic) in a compact envelope.
Precision Engineering: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (0.0000 – 0.0005"), ensuring consistent performance and smooth operation. The nylon cage contributes to quiet operation and reduced friction at higher speeds.
Enhanced Durability: The Endura-kote chromium plating on chrome steel components provides superior protection against corrosion, extending bearing life in challenging environments. The bearing operates effectively across a wide temperature range (-30°C to 110°C).
High Load Capacity: Despite its thin section, the NAA10XL0 delivers impressive load ratings - 247 lbf radial dynamic, 370 lbf axial dynamic, and 730 lbf axial static - making it suitable for applications requiring substantial bearing performance in limited spaces.
