Cylindrical Roller Bearings FAG NU319 -E-XL-M1-C3

FAG NU319 -E-XL-M1-C3 cylindrical roller bearing: A single-row non-locating bearing with a brass cage, measuring 95 x 200 x 45 mm, designed for demanding radial loads.

The FAG NU319 -E-XL-M1-C3 cylindrical roller bearing is an open, single-row roller bearing designed to accommodate high radial forces in industrial applications. With a bore of 95 mm, an outer diameter of 200 mm and a width of 45 mm, this roller bearing provides stable guidance for heavy shafts. The NU design functions as a pure idler bearing, in which the inner ring can be removed from both sides. This simplifies both installation and the compensation for thermal length changes.

What is the NU319 -E-XL-M1-C3 cylindrical roller bearing suitable for?

This non-locating bearing is primarily used where high radial forces are present and axial displacements of the shaft relative to the housing must be compensated for without causing stress. Typical applications can be found in general mechanical engineering and in mechanical drives subject to purely radial loads. Thanks to its solid brass cage, the bearing is well suited to environments with strong oscillations, vibrations or rapid changes in rotational speed. As the outer ring has no groove or lubrication bore, the lubricant is supplied via the surrounding housing design.

What features do the brass cage and C3 clearance offer in this design?

The combination of the robust brass cage (M1) and the slightly increased radial bearing clearance (C3) enhances the operational flexibility of this rolling bearing. The brass cage guides the cylindrical rollers securely and retains its dimensional stability even under dynamic loads. The increased C3 bearing clearance serves to compensate for fit allowances and temperature differences between the inner and outer rings without the bearing becoming stressed during operation. With a permissible temperature range of -30 to +150 degrees, the bearing is suitable for thermally demanding operating conditions.
