The N312 ECM is a specific type of cylindrical roller bearing. Here’s a breakdown of its key features and specifications:

Cylindrical Roller Bearing N312 ECM

1. Type: Cylindrical Roller Bearing
   • Cylindrical roller bearings are designed to handle high radial loads and moderate axial loads. They are commonly used in applications requiring high rigidity and precision.
2. Bearing Designation:
   • 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 (mm) = 312 × 5 = 60 mm.
   • 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. Ngā Ahu:
   • Bore Diameter (d): 60 mm
   • Outer Diameter (D): 130 mm
   • Whānui (B): 31 mm
   • These dimensions are standard for the N312 bearing series.
4. Load Capacity:
   • 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. Applications:
   • Commonly used in heavy-duty machinery, such as:
     • Gearboxes
     • Electric motors
     • Pumps
     • Industrial fans
     • Machine tools
6. Advantages:
   • High radial load capacity.
   • 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:
   • The 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.
