Cylindrical Roller Bearings FAG NJ2222 -E-XL-M1-C3

The FAG NJ2222 -E-XL-M1-C3 cylindrical roller bearing (110x200x53 mm) offers high radial load capacity, single-sided axial guidance and robust guidance provided by a brass cage.

The NJ2222 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG in the NJ design. With a bore of 110 mm, an outer diameter of 200 mm and a width of 53 mm, this open bearing can withstand high radial loads. Thanks to the flanges on the outer and inner rings, the component acts as a thrust bearing, thereby limiting axial displacement of the shaft in one direction.

What loads can the NJ2222 -E-XL-M1-C3 cylindrical roller bearing accommodate?

Designs subject to significant radial loads typically use this design as a support bearing. Due to the line contact between the rollers and the raceway, the roller bearing withstands high radial forces. In combination with a suitable mating bearing, the NJ design also withstands axial forces on one side, whilst the inner ring can be removed separately for installation and maintenance purposes.

What is the function of the brass cage and the C3 radial clearance in this cylindrical roller bearing?

The M1 version features a brass cage that guides the rollers even under highly vibratory operating conditions. The slightly increased radial clearance (C3) compensates for operational heating as well as fit allowances on the shaft or housing. As the bearing is of open design and the outer ring has no lubrication bore, the lubricant is supplied directly via the housing cavity within a temperature range of -30 to +150 degrees Celsius.
