Cylindrical Roller Bearings FAG N319 -E-M1

The FAG N319 -E-M1 cylindrical roller bearing (95x200x45 mm) is an open idler bearing with a brass cage that can withstand high radial loads.

This single-row cylindrical roller bearing N319 -E-M1 from FAG is characterised by its compact design and high radial load-carrying capacity. With a bore diameter of 95 mm, an outside diameter of 200 mm and a width of 45 mm, this design is suitable for heavy-duty applications in mechanical and plant engineering. The open roller bearing has standard radial clearance and is designed for a temperature range of –30 to +150 degrees Celsius.

What is the function of the N319 -E-M1 idler bearing during operation?

The N319 -E-M1 cylindrical roller bearing is designed to specifically accommodate purely radial loads in rotating shaft guides. As the outer ring is detachable on both sides, the unit functions as a classic non-locating bearing. This design compensates for axial changes in shaft length caused by thermal expansion during operation, without any forced alignment within the bearing housing. Furthermore, the separable design facilitates the separate installation of both bearing rings.

What are the advantages of the brass cage in the -E-M1 design?

The solid brass cage (designation M1) guides the cylindrical rollers precisely and, compared to standard cages, offers high dimensional stability under vibrations or shock loads. Furthermore, brass is resistant to aggressive lubricants. With its classification in tolerance class P0 (ABEC 1), the roller bearing complies with the standardised accuracy requirements for industrial applications.
