Cylindrical Roller Bearings FAG NU1010 -M1-C3

The FAG NU1010 -M1-C3 cylindrical roller bearing (50x80x16 mm) is a single-row idler bearing designed to accommodate high radial forces during thermal linear expansion.

The FAG NU1010 -M1-C3 cylindrical roller bearing is an open, single-row roller bearing with a 50 mm bore, an 80 mm outer diameter and a width of 16 mm. It is primarily designed to accommodate high radial loads in mechanical engineering. In the NU design, the outer ring guides the rollers between two fixed flanges, whilst the inner ring has no flanges. This allows the inner ring to be removed from both sides, which facilitates separate assembly.

What is the NU1010 -M1-C3 cylindrical roller bearing suitable for?

This rolling bearing primarily functions as a non-locating bearing in shaft mountings. As the inner ring has no flanges, the design compensates directly within the bearing for axial displacement of the shaft relative to the housing. This prevents thermally induced stresses during operation. Typical applications include bearing arrangements where purely radial forces are acting and no axial guidance is required at this bearing location.

What is the purpose of the brass cage and C3 clearance in this design?

The solid brass cage, marked M1, guides the rollers stably and is suitable for mechanically demanding environments involving vibrations or shock loads. The suffix C3 indicates an increased radial clearance. This compensates for operational temperature differences between the inner and outer rings, as well as constrictions caused by tight fits. As the design does not incorporate sealing washers, sealing is provided by the surrounding housing structure. The lubrication system must be designed to suit the temperature range from -30 to +150 degrees.
