Applicable Machines and Industries
The NU 217 ECM/C3VL0241 Single Row Cylindrical Roller Bearing is commonly used in various industrial applications, especially where high radial load capacity and insulation from electric currents are required. This bearing is well-suited for machines that involve heavy-duty operations, such as:
Suitable Machines:
- Electric Motors & Generators: These bearings are used to prevent electrical currents from passing through, protecting the machine from electric erosion.
- Pumps: Particularly in industrial fluid pumps where axial loads are minimal and the bearing needs to handle high radial loads.
- Gearboxes: Used in gearboxes for heavy-duty industrial machinery, offering high load capacity and insulation from stray electrical currents.
- Conveyor Systems: Used in heavy industrial conveyor systems, which require robust bearings for long-lasting performance.
- Wind Turbines: These bearings are commonly found in wind turbine gearboxes to handle the high loads generated by wind forces.
- Traction Motors (Railway): This bearing type is useful in electric traction motors to isolate the motor from electrical current damage.
- Steel Mills & Rolling Mills: They are used in large rolling machines due to their ability to handle high radial loads.
Role in Machines:
- Electric Insulation: The primary function of the NU 217 ECM/C3VL0241 is to protect the machine from stray electric currents. The bearing’s coating (usually an insulating layer) prevents damage caused by electrical discharge, commonly known as electric erosion or pitting.
- Radial Load Handling: It supports heavy radial loads while allowing some axial displacement between the shaft and housing, which is essential in machines subjected to heavy radial forces.
- Reduced Maintenance: By preventing electric discharge and reducing wear and tear, the bearing minimizes maintenance needs and increases machine lifespan.
