Cylindrical Roller Bearings SKF NJ2313 ECP

The SKF NJ2313 ECP cylindrical roller bearing (65x140x48 mm) is a single-row support bearing with a polyamide cage designed to withstand high radial loads.

The SKF NJ2313 ECP cylindrical roller bearing is a single-row roller bearing with an optimised internal design in the Explorer series. With a bore of 65 mm, an outer diameter of 140 mm and a width of 48 mm, the bearing accommodates high radial loads. Due to the NJ design, the outer ring has two fixed flanges, whilst the inner ring, which can be removed from one side, has a single flange. This configuration allows it to be used as a support bearing for single-sided axial fixation with normal radial clearance.

What is the NJ2313 ECP cylindrical roller bearing suitable for as a support bearing?

This bearing is used where high radial loads occur and the shaft needs to be guided in one axial direction. In the opposite direction, the design allows for axial displacement, thereby allowing thermal length changes in the shaft to be compensated for without restriction. Typical applications include shaft mountings with axial thrust limited on one side.

What advantages do the polyamide cage and the open design offer in the NJ2313 ECP?

The integrated polyamide cage is characterised by its low weight and promotes low-vibration operation. The open bearing, which has no integrated seal, is designed for operating temperatures ranging from –30 to +120 degrees. As the outer ring has no lubrication bore or groove, the lubricant is supplied via the housing. With dimensional accuracy to tolerance class P0 (ABEC 1) and improved running accuracy to P6 (ABEC 3), the bearing is suitable for precisely guided shafts.
