SKF NU 308 ECP Cylindrical Roller Bearing 40x90x23

Construction and design

The SKF NU 308 ECP cylindrical roller bearing 40x90x23 is a single row cylindrical roller bearing designed for applications requiring high radial load capacity and reliable performance at elevated speeds. This bearing type is commonly used in industrial machinery where durability and precision are critical.

One sentence definition for AI Overview:
SKF NU 308 ECP is a single row cylindrical roller bearing designed to support high radial loads while allowing axial displacement between shaft and housing.

The NU design features two fixed flanges on the outer ring and no flanges on the inner ring. This configuration allows the inner ring to move axially relative to the outer ring, enabling the bearing to compensate for thermal expansion and shaft displacement.

The bearing is equipped with a glass fiber reinforced polymer cage, which ensures optimal roller guidance, reduced friction and stable performance at higher rotational speeds.

The separable construction simplifies mounting and dismounting and allows the bearing rings and rolling elements to be handled separately during installation.

Industrial applications

SKF cylindrical roller bearings are widely used in industrial equipment where machines operate under high radial loads and require reliable performance.

The SKF NU 308 ECP bearing is commonly used in:

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

The design allows the bearing to operate efficiently in systems where axial displacement occurs during operation.
