Cylindrical Roller Bearings FAG NJ2228 -E-XL-M1-C3

The FAG NJ2228 -E-XL-M1-C3 cylindrical roller bearing, with dimensions of 140 x 250 x 68 mm, a brass cage and C3 clearance, offers high load-carrying capacity for demanding industrial applications.

The single-row cylindrical roller bearing NJ2228 -E-XL-M1-C3 from FAG withstands very high radial forces and is designed to function as a support bearing. The outer ring has two fixed flanges, whilst the inner ring has one fixed flange and remains removable on one side. Consequently, the bearing arrangement permits axial displacement in one direction. Manufactured to standard tolerances in accordance with P0 or ABEC 1, this design meets common standards for mechanical and plant engineering.

What is the NJ2228 design with support bearing function suitable for?

Typical applications include situations where heavy radial loads act on the shaft and thermally induced length changes must be compensated for without restriction. As a support bearing, the NJ2228 absorbs axial forces in one direction, whilst allowing free axial movement in the opposite direction. The separable design also facilitates the separate assembly of the inner and outer rings in complex bearing arrangements.

What do the brass cage and C3 clearance mean for this bearing?

The solid brass cage guides the cylindrical rollers precisely and proves particularly effective in the presence of strong vibrations or fluctuating speeds. The increased radial clearance (C3) compensates for operational heating, ensuring that the bearing clearance is maintained even when the shaft and housing expand due to heat. As this model is designed as an open bearing, lubrication is provided via the surrounding housing structure within an operating temperature range of -30 to +150 degrees Celsius.
