NC300XP0 Bearing Product Overview & Core Advantages
The NC300XP0 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 is designed to simultaneously handle combined radial and axial loads from any direction. Its single-row construction with optimized geometry delivers exceptional load moment capacity (49 ft-lbf rated) while maintaining minimal cross-section dimensions, making it ideal for space-constrained, high-reliability applications in demanding environments.

NC300XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The unique raceway geometry enables the bearing to support combined radial and axial loads in both directions simultaneously, eliminating the need for multiple bearing arrangements.
Thin-Section Construction: With a minimal cross-section of only 0.375" width, this bearing provides maximum space efficiency while maintaining high load capacity (4,338 lbf dynamic radial, 8,050 lbf dynamic axial).
Premium Material Selection: Chrome steel rings and balls combined with brass cage construction ensure dimensional stability and reliable operation under varying load conditions.
Enhanced Surface Protection: The Endura-kote chromium plating provides superior corrosion resistance, extending service life in harsh environments while maintaining precise bearing dimensions.
Optimized Internal Clearance: Tight radial internal clearance (0.0000 – 0.0005") ensures precise rotational accuracy and minimal runout for high-precision applications.
