The SKF NJ EV/C series cylindrical roller bearing is a radial bearing with high load capacity that allows axial displacement in one direction. It is used in applications where significant radial forces must be supported while, at the same time, allowing the shaft to move due to thermal expansion. MR Accesorios Industriales supplies this line with the technical backing of more than 80 years in the industry.

The designation of these bearings is read in parts. The initial letters NJ indicate that the outer ring has two ribs and the inner ring one, which allows axial displacement in one direction. The number that follows, as in the example NJ 2004 EV/C3, identifies the size and dimensional series. The suffix EV indicates a machined brass cage design, suitable for high speeds and loads. The slash and the final letter C accompany internal clearance variants, such as C3, which increases radial clearance for operation at elevated temperatures.

These bearings are chosen in industries where radial load is demanding and speeds are moderate to high. In Argentina they are found in gearboxes, centrifugal pumps, industrial fans, machine tools and power transmission equipment. They also appear in railway applications and in the cement industry, where long shafts need freedom for expansion. Their ability to support combined loads makes them versatile in assemblies where a conventional rigid bearing cannot be used.

To select the correct bearing, the type of sealing, internal clearance and lubrication must be considered. The NJ EV/C series is usually mounted with oil or grease lubrication, depending on speed and operating temperature. It is essential to verify shaft and housing alignment, because excessive misalignment shortens service life. Internal clearance C3 is recommended when there are significant thermal gradients between the inner and outer rings. The machined brass cage better tolerates shocks and accelerations.

As for equivalents, cylindrical roller bearings from other brands can be interchanged if the main dimensions and design type match. It is not enough for the part number to be similar: inner diameter, outer diameter, width and rib configuration must be compared. An NJ bearing from another company can replace an SKF one if it maintains the same load capacity and the same clearance. It is always advisable to consult a specialist before replacing a critical component.
