NB055XP0 Bearing Product Overview & Core Advantages
The NB055XP0 is a thin section four-point contact ball bearing engineered for applications requiring high precision and compact design. Featuring Endura-kote chromium plating for enhanced corrosion resistance, this bearing excels in handling combined radial and axial loads simultaneously through its optimized four-point contact geometry. With an ABEC-1 precision class and inch-dimensioned construction (5.5" bore), it delivers reliable performance in space-constrained assemblies where high rigidity and lightweight design (0.41 lbs) are critical.

NB055XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: Enables the bearing to handle combined radial and axial loads in any direction with minimal deflection, providing exceptional moment load capacity (Dynamic: 2844 lbf, Static: 6850 lbf).
Thin Section Construction: With a cross-section of only 0.3125" width, this bearing maximizes space utilization while maintaining high rigidity and precise dimensional stability.
Endura-kote Chromium Plating: Provides superior corrosion protection and extended service life in harsh environments, complementing the chrome steel rings and brass cage construction.
Precision Engineering: ABEC-1 tolerance class and tight dimensional controls ensure smooth operation and reliable performance in precision applications.
