Cylindrical Roller Bearings SKF NU310 ECJ

The SKF NU310 ECJ cylindrical roller bearing (50x110x27 mm) is a separable idler bearing with a sheet steel cage designed to withstand high radial loads.

The SKF NU310 ECJ cylindrical roller bearing is a single-row radial roller bearing with a 50 mm bore, an 110 mm outer diameter and a width of 27 mm. Thanks to its optimised internal design, this bearing can accommodate high radial loads. It is used as a loose bearing, where the inner ring can be removed from both sides. The open component features a sheet steel cage and is designed for a temperature range of -30 to +150 degrees.

In which bearing arrangements is the NU310 ECJ cylindrical roller bearing used?

The rolling bearing accommodates purely radial forces and compensates for axial changes in the length of the shaft. The NU design allows for free axial movement of the shaft relative to the housing directly within the bearing. Typical applications are found in radially loaded bearing arrangements in mechanical engineering. As the outer ring has fixed flanges and the inner ring is flangeless, the roller bearing can be fitted separately during assembly.

What is the function of the sheet steel cage and the tolerance class in the NU310 ECJ?

In the NU310 ECJ cylindrical roller bearing, the sheet steel cage guides the cylindrical rollers evenly whilst maintaining a compact footprint. The manufacturing process combines dimensional accuracy to P0/PN (ABEC 1) with increased running accuracy to P6 (ABEC 3). This makes the bearing suitable for precisely guided shafts with normal radial clearance. As this is an open bearing without an integrated seal, the lubricant supply and external housing seals are selected to suit the ambient conditions.
