Cylindrical Roller Bearings SKF NJ2314 ECP

The SKF NJ2314 ECP cylindrical roller bearing, measuring 70x150x51 mm, can accommodate high radial loads as well as axial loads in one direction.

This single-row NJ2314 ECP cylindrical roller bearing in the Explorer design features an optimised internal construction for demanding bearing applications. With a bore of 70 mm, an outside diameter of 150 mm and a width of 51 mm, the bearing is suitable for mechanically stressed designs. Designed as an open bearing, it can be flexibly integrated into an existing lubrication system. The outer ring has no groove or lubrication bore, whilst the standard radial clearance ensures smooth running at normal operating temperatures.

What are the practical applications of the NJ2314 ECP cylindrical roller bearing?

Typical applications include bearing locations where high radial forces occur and axial forces need to be supported in one direction. Due to its NJ design, this roller bearing functions as a support bearing: the inner ring has a fixed flange on one side, which means the bearing limits axial displacement of the shaft in one direction whilst allowing it in the opposite direction. Designs involving operationally induced linear expansion of shafts utilise this controlled axial displacement without the need for additional components to compensate for linear expansion.

What are the advantages of a polyamide cage and a removable inner ring?

The polyamide cage guides the cylindrical rollers quietly and reduces the moment of inertia of the rotating mass. This material is designed for a temperature range of -30 to +120 degrees. A key installation advantage lies in the inner ring, which can be removed from one side: the inner ring and outer ring, together with the roller set, can be mounted separately onto the shaft and housing. Combined with the dimensional accuracy P0 (ABEC 1) and the higher running accuracy P6 (ABEC 3), this simplifies installation in confined spaces.
