Cylindrical Roller Bearings FAG NJ208 -E-M1

The NJ208 -E-M1 cylindrical roller bearing from FAG Wälzlager, with dimensions of 40x80x18 mm, offers high radial load-carrying capacity and axial guidance in one direction.

The NJ208 -E-M1 cylindrical roller bearing from FAG Wälzlager is a single-row roller bearing designed to withstand high radial loads. The version with a brass cage is characterised by dimensional stability within a temperature range of -30 to +150 degrees. The outer ring has two solid flanges, whilst the inner ring has one solid flange. Thanks to this design, the roller bearing functions as a support bearing that guides shafts in an axial direction.

In which installation situations is the NJ208 -E-M1 cylindrical roller bearing used?

This design is suitable for bearing arrangements subject to high radial forces, where axial guidance of the shaft in one direction is also required. The bearing allows axial displacement in the opposite direction. As the inner ring can be removed from one side, the shaft and housing can be fitted separately. In bearing arrangements, the NJ design is frequently used to provide single-sided axial support whilst ensuring high rigidity at the bearing location.

What are the distinctive features of the version with a brass cage?

The brass cage, identified by the suffix M1, guides the cylindrical rolling elements and is designed to withstand mechanical loads and accelerations. The material retains its dimensional stability even at elevated operating temperatures ranging from -30 to +150 degrees. As this is an open bearing without integrated seals, provision must be made for lubricant supply via the housing and for external sealing of the bearing location.
