Cylindrical Roller Bearings SKF NU2310 ECP

The SKF NU2310 ECP single-row cylindrical roller bearing, with a 50 mm bore and a polyamide cage, offers a robust non-locating bearing solution for purely radial forces.

The SKF NU2310 ECP cylindrical roller bearing is an open-type radial roller bearing. With dimensions of a 50 mm bore, 110 mm outer diameter and 40 mm width, the 2310 series can accommodate high radial loads. The cylindrical rollers create a line-contact arrangement on the raceways, which contributes to high structural rigidity. The manufacturer produces the bearing in the Explorer version with an optimised internal design for smooth running.

What is the NU2310 ECP cylindrical roller bearing suitable for as a support bearing?

The NU design is suitable for bearing arrangements where purely radial forces act and axial displacement occurs between the shaft and housing. The outer ring has two fixed guide flanges, whilst the flangeless inner ring can be removed from both sides. This allows the component to compensate for thermal length changes in the shaft without constraint within the bearing. Typical applications include radially loaded shaft positions with separate axial fixation.

What are the distinctive features of the ECP version with a polyamide cage?

The suffix ECP denotes the combination of an optimised internal design and a polyamide cage. This cage material reduces the weight of the rotating components and promotes quiet operation. The bearing is designed for use within a temperature range of -30 to +120 degrees. Dimensional accuracy complies with tolerance class P0/PN (ABEC 1), whilst running accuracy is manufactured to class P6 (ABEC 3). As the bearing is of open design, lubrication is provided by grease or oil within the housing.
