NU322.EM.C3 Single Row NU Type Cylindrical Roller Bearing 110×240×50mm EM Machined Brass Cage C3 Internal Clearance For Heavy Mining Equipment & Industrial Reducers

NU322.EM.C3 is a single-row NU series cylindrical roller bearing with double ribs on outer ring and ribless inner ring. It adopts EM solid machined brass cage and C3 enlarged radial clearance. This bearing mainly bears heavy radial load and allows axial displacement between inner and outer rings, adapting to thermal expansion of high-temperature heavy machinery. With strong impact resistance, it is widely applied in mining crushers, heavy reducers and large conveying equipment under severe working conditions.
