Cylindrical Roller Bearings FAG NU312 -E-XL-M1-C3

The FAG NU312 -E-XL-M1-C3 cylindrical roller bearing (60x130x31 mm) serves as a separable support bearing for high radial loads at temperatures up to +150 degrees.

The FAG NU312 -E-XL-M1-C3 cylindrical roller bearing is a single-row roller bearing designed for demanding industrial applications. With a bore of 60 mm, an outside diameter of 130 mm and a width of 31 mm, the component is primarily designed to withstand high radial loads. In the NU design, the outer ring has two fixed flanges, whilst the inner ring is flangeless and can be removed from both sides. This design facilitates the separate assembly of both bearing rings.

What is the NU312 -E-XL-M1-C3 cylindrical roller bearing suitable for?

As a typical floating bearing, this design accommodates changes in shaft length due to thermal expansion without restriction within the bearing. Typical applications include bearing arrangements subject to high radial loads, where axial forces are supported by separate bearing units. As the open bearing is left unfilled at the factory, you can flexibly integrate it into existing lubrication systems using oil or grease. The permissible temperature range is from -30 to +150 degrees.

What functions do the brass cage and C3 bearing clearance fulfil in this design?

The solid brass cage (M1) guides the cylindrical rollers precisely and withstands high accelerations and vibrations. In addition, the increased radial clearance (C3) compensates for operational heating and tight fits. During installation, the radial clearance is reduced, ensuring smooth running during normal operation. Please observe tolerance class P0 (ABEC 1) when machining the bearing seats and ensure a clean external seal is fitted, as the open bearing has no integrated seals.
