SKF NJ-326-ECJ C4 Cylindrical Roller Bearing

SKF NJ 326 ECJ/C4 is a single-row cylindrical roller bearing with a bore of 130 mm, an outer diameter of 280 mm, and a width of 58 mm, engineered to support high radial loads in heavy-duty industrial machinery. The ECJ designation denotes SKF’s EC design, which provides improved guiding surfaces on flange faces and roller ends to increase stiffness and axial-load carrying capacity, while the C4 suffix indicates a larger-than-normal internal clearance suitable for thermal expansion and dynamic service. A pressed steel cage (suffix J) keeps the rollers evenly spaced for reliable load distribution, and the bearing is manufactured from standard bearing steel to withstand repeated cycling in challenging environments. Common applications include heavy-duty conveyors, rolling mills, crushers, and other industrial equipment where robust radial support and long life under demanding operating conditions are essential. Exact dynamic and static load ratings, limiting speeds, and mounting tolerances are defined in SKF’s NJ-series specifications and should be consulted from the supplier’s data sheet for this model.
