NA055XP0 Bearing Product Overview & Core Advantages
The NA055XP0 is a precision thin-section four-point contact ball bearing designed for applications requiring exceptional space efficiency and high load capacity. Featuring Endura-Kote chromium plating, this single-row bearing excels in handling combined radial and axial loads from any direction simultaneously. Its inch-series construction with ABEC-1 precision ensures reliable performance in compact assemblies where high rigidity and dimensional stability are critical.
NA055XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| NA055 | Bearing series designation for thin-section four-point contact design | Optimized for space-constrained applications |
| XP0 | Specific variant with chromium plating and open construction | Enhanced corrosion resistance and thermal stability |
NA055XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: Enables the bearing to support combined radial and axial loads in any direction, making it ideal for complex loading conditions. The optimized raceway geometry distributes stress evenly across contact points.
Thin-Section Construction: With a consistent 0.25" cross-section, this bearing maximizes space utilization while maintaining high rigidity and dimensional stability in lightweight assemblies.
Endura-Kote Chromium Plating: Provides superior corrosion protection and reduced friction characteristics, extending service life in demanding environments while maintaining precise bearing dimensions.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional controls (bore and OD tolerance: -0.0010" to 0") ensures consistent performance and easy installation.
Brass Cage Construction: Provides excellent guidance and stability for the chrome steel balls, contributing to smooth operation and extended bearing life.
