Cylindrical Roller Bearings FAG NU2313 -E-XL-M1A-C4

At a glance: Single-row FAG cylindrical roller bearing NU2313 -E-XL-M1A-C4 (65x140x48 mm) as a support bearing with a solid brass cage and increased C4 clearance for high radial loads.

The FAG NU2313 -E-XL-M1A-C4 cylindrical roller bearing, as a single-row radial roller bearing, accommodates high radial forces. In the NU design, the outer ring guides the rollers between two fixed flanges, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, making the bearing suitable as a classic free-running bearing for shaft guides requiring potential axial compensation. The open component has the following main dimensions: 65 mm bore, 140 mm outer diameter and 48 mm width.

What is the NU2313 -E-XL-M1A-C4 cylindrical roller bearing suitable for?

This cylindrical roller bearing is primarily suitable for mechanical engineering applications where purely radial loads predominate and thermal length changes in the shaft need to be accommodated. The NU design allows axial displacement between the shaft and housing to be accommodated freely within the bearing itself. It is typically used in free-end positions of shaft bearings subject to high impact or vibration loads. The externally guided solid brass cage ensures stable guidance of the rollers even under dynamic loads or increased vibrations.

What do the C4 bearing clearance and the M1A brass cage mean for your application?

The significantly increased radial clearance (C4) provides more radial play than a standard bearing. This is crucial when high fit allowances or temperature differences between the inner and outer rings occur during operation. The bearing covers a temperature range from minus 30 to plus 150 degrees. As the bearing is of open design and the outer ring has no lubrication bore, sealing and lubrication are provided via the housing. The bearing is manufactured to tolerance class P0 or ABEC 1.
