Cuscinetti a rulli cilindrici

Le N312 ECM is a specific type of cylindrical roller bearing. Ecco una ripartizione delle sue caratteristiche e specifiche principali:

Cylindrical Roller Bearing N312 ECM

1. Digitare: Cuscinetto a rulli cilindrici
   • I cuscinetti a rulli cilindrici sono progettati per gestire carichi radiali elevati e carichi assiali moderati. They are commonly used in applications requiring high rigidity and precision.
2. Designazione del cuscinetto:
   • N312: This indicates the bearing’s size and series.
     • N: Non-locating bearing (no flanges on the outer ring, allowing axial displacement).
     • 312: Refers to the bore diameter and dimensions.
       • The bore diameter can be calculated as follows:
         Bore diameter (millimetro) = 312 × 5 = 60 millimetro.
   • ECM: This suffix indicates specific design features:
     • EC: Optimized internal design with more and/or larger rollers, increasing load capacity.
     • M: Machined brass cage, which provides better strength and durability compared to stamped steel cages.
3. Dimensioni:
   • Diametro foro (d): 60 millimetro
   • Diametro esterno (D): 130 millimetro
   • Larghezza (B): 31 millimetro
   • These dimensions are standard for the N312 bearing series.
4. Portata:
   • High radial load capacity due to the cylindrical roller design.
   • Moderate axial load capacity (only in the axial direction allowed by the bearing design).
5. Applicazioni:
   • Commonly used in heavy-duty machinery, such as:
     • Riduttori
     • Motori elettrici
     • Pompe
     • Industrial fans
     • Macchine utensili
6. Vantaggi:
   • Elevata capacità di carico radiale.
   • Low friction and high-speed capability.
   • Precision and rigidity for demanding applications.
   • Brass cage (M) provides better performance in high-speed and high-temperature environments.
7. Lubrication:
   • Requires proper lubrication (grease or oil) to ensure smooth operation and long service life.
8. Mounting:
   • Le N designation indicates that the outer ring can move axially relative to the inner ring, making it suitable for applications with thermal expansion or misalignment.
