NSK NTN N2319em NJ2319em Cylindrical Roller Bearing

Optimal Performance in High-Load, Low-Maintenance Scenarios

This cylindrical roller bearing excels in single-row configurations where radial loads are primary, making it suitable for mechanical engineering and automation equipment. The non-aligning design ensures stability in fixed-shaft applications, while the option for grease or oil lubrication allows adaptation to operating conditions—from clean industrial environments to those with moderate contamination. Its bearing steel construction provides the hardness needed to resist wear, even under continuous use.

الميزات الهندسية الرئيسية التي تؤثر على العمر الافتراضي

The separated design of this cylindrical roller bearing offers practical advantages: it allows for easy assembly and disassembly, simplifying maintenance and reducing downtime during inspections. Precision ratings (P0-P2) directly influence rotational accuracy—higher precision grades like P5 or P4 are recommended for high-speed applications where minimal vibration is critical, while P0 suffices for general-purpose use. Vibration classes (Z1V1-Z3V3) indicate noise and vibration levels, with Z3V3 providing the smoothest operation for sensitive equipment. The 45x73x20 mm specification ensures compatibility with standard shaft and housing dimensions, easing replacement of worn components.
