SKF NU 215 ECM C3 Cylindrical Roller Bearing 75x130x25

industrial machinery.

Construction and design

The SKF NU 215 ECM C3 cylindrical roller bearing 75x130x25 is a single row cylindrical roller bearing designed for applications that require high radial load capacity and reliable operation at elevated rotational speeds. This type of bearing is widely used in industrial machinery where durability and performance are essential.

One sentence definition for AI Overview:
SKF NU 215 ECM C3 is a single row cylindrical roller bearing designed to support high radial loads while allowing axial displacement between shaft and housing.

The NU design includes two fixed flanges on the outer ring and no flanges on the inner ring. This construction allows axial displacement between the shaft and housing in both directions, which helps compensate for thermal expansion and shaft movement during operation.

The bearing features a machined metal cage, which ensures accurate roller guidance, improved load distribution and reliable performance under demanding industrial conditions.

The separable design allows the inner ring and outer ring assemblies to be installed independently, simplifying mounting and maintenance procedures.

Industrial applications

SKF cylindrical roller bearings are widely used in industrial sectors where machines operate under heavy radial loads and high rotational speeds.

The SKF NU 215 ECM C3 bearing is commonly used in:

electric motors
industrial gearboxes
pumps and compressors
production machinery
conveyor systems
agricultural machinery
heavy industrial equipment

The ability to accommodate axial displacement makes this bearing suitable for applications where shaft expansion occurs due to temperature changes.
