NNU 4922 MP51 DKF 110x150x40 double row cylindrical roller bearing

Main description

The NNU 4922 MP51 DKF cylindrical roller bearing with dimensions 110x150x40 mm is a heavy duty double row bearing designed for applications requiring extremely high radial load capacity, high rigidity and stable operation under demanding industrial conditions.

A cylindrical roller bearing is engineered to support heavy radial loads through line contact between rollers and raceways. The NNU design features two rows of cylindrical rollers, significantly increasing load carrying capacity and structural stiffness compared to single row bearings.

The NNU 4922 MP51 DKF is widely used in precision machinery and heavy industry, where maintaining shaft stability and minimizing deflection under load is critical. Its configuration allows axial displacement within the bearing, making it suitable for applications where thermal expansion of the shaft must be accommodated.

This bearing is particularly effective in high load environments where reliability and consistent performance are required over long operating periods.

Construction and design

The DKF NNU 4922 MP51 is a double row cylindrical roller bearing with an inner ring featuring two flanges and an outer ring without flanges.

This design allows the bearing to accommodate axial displacement between shaft and housing, reducing internal stress caused by thermal expansion. The MP51 cage is a machined brass cage that provides excellent strength, stability and performance under high loads and speeds.

The two row configuration ensures even load distribution and increased rigidity, making the bearing suitable for precision and heavy duty applications.

Industrial applications

This cylindrical roller bearing is used in demanding industrial systems where high load capacity and rigidity are required.

Typical applications include:
machine tools and precision spindles
heavy industrial machinery
gearboxes and transmission systems
main shafts in industrial equipment
metal processing and production lines
