FAG NJ 304 ETVP 20x52x15 cylindrical roller bearing

Industrial applications

The FAG NJ 304 ETVP 20x52x15 cylindrical roller bearing is designed for systems where high radial loads must be supported together with controlled axial positioning in one direction.

This bearing is commonly used in:

• industrial gearboxes
• electric motors
• production machinery
• drive systems
• pumps and compressors

Within the cylindrical roller bearings FAG category on simmering.pl, the NJ 304 ETVP model functions as a semi-locating bearing, working together with NU or NUP types in advanced mechanical systems.

Construction and design

The FAG NJ 304 ETVP cylindrical roller bearing features a NJ design, allowing axial guidance of the shaft in one direction.

Key design features:

• cylindrical rollers with line contact for high load capacity
• outer ring with two fixed flanges
• inner ring with one flange enabling axial positioning
• ETVP cage reducing friction and weight

The ETVP cage improves efficiency and allows higher rotational speeds compared to heavier cage designs.
