Cylindrical Roller Bearings FAG NJ2317 -E-XL-M1-C3

The FAG NJ2317 -E-XL-M1-C3 cylindrical roller bearing, measuring 85x180x60 mm, offers high radial load-carrying capacity and axial guidance in one direction.

The NJ2317 -E-XL-M1-C3 cylindrical roller bearing is a single-row roller bearing from FAG, designed for demanding industrial applications. Thanks to the line contact between the rollers and raceways, this design can withstand very high radial loads. Designed as an open bearing, it can be flexibly integrated into the system’s existing lubrication system. It is manufactured to the standard tolerance class P0/PN (ABEC 1), meaning it complies with common industrial installation standards.

What function does the NJ design fulfil as a support bearing?

This design is used in bearing arrangements where heavy radial loads prevail. Thanks to its NJ design, the bearing also serves as a support bearing: in addition to radial loads, it absorbs axial guidance forces from one direction. The inner ring is removable on one side, which facilitates the separate assembly of the inner and outer rings. As the outer ring is designed without a groove or lubrication bore, the lubricant is supplied via the housing design.

What is the function of the brass cage and the C3 clearance?

The solid brass cage (M1) guides the cylindrical rollers reliably and is also suitable for use under vibrations or accelerations. In combination with the slightly increased radial clearance (C3), the bearing is suitable for operating conditions involving thermal expansion. The additional clearance compensates for temperature differences between the inner and outer rings without causing stress. The permissible operating temperature range is from -30 to +150 degrees.
