Cylindrical Roller Bearings SKF NJ2215 ECP

The SKF NJ2215 ECP cylindrical roller bearing (75x130x31 mm) withstands high radial loads and supports shafts axially on one side as a support bearing.

The NJ2215 ECP cylindrical roller bearing is a single-row rolling bearing in the SKF Explorer series with a 75 mm bore, 130 mm outside diameter and 31 mm width. Thanks to its optimised internal design and lightweight polyamide cage, this bearing is designed to handle demanding radial loads. Designed as an open bearing, it requires an external lubricant supply and housing seals. Dimensional accuracy complies with P0/PN (ABEC 1), whilst running accuracy is manufactured to P6 (ABEC 3).

What loads can the NJ2215 ECP cylindrical roller bearing accommodate?

This rolling bearing is primarily used to support high radial forces in machinery and plant. The NJ design acts as a support bearing: it absorbs axial forces from one direction but allows axial displacement in the opposite direction. In this way, the bearing compensates for thermally induced changes in shaft length without any binding. It is typically used in bearing arrangements where radial loads predominate and single-sided axial guidance is required.

What are the distinctive features of the NJ design and the polyamide cage?

The outer ring has two solid flanges, whilst the inner ring has a single flange and remains removable from one side. This separability facilitates both installation and removal, as the inner and outer rings can be fitted separately. The elastic polyamide cage dampens vibrations and ensures smooth running within a temperature range of -30 to +120 degrees. The bearing has standard radial clearance and requires a clean housing environment protected from contamination.
