The NU series cylindrical roller bearing is a radial bearing with high load capacity, featuring an outer ring, inner ring and a set of cylindrical rollers guided between flanges. It is used where there are high radial loads and high speeds, and where the shaft needs to move axially within the housing. MR Accesorios Industriales sells the NSK line in Buenos Aires, Argentina, and quotes the part number or size you need on WhatsApp.

The NU series designation is read in blocks: the letters NU indicate the flange arrangement of the bearing, and the number that follows is the dimension code. In the examples in this family, the codes share the NU series with different sizes; the final M indicates the cage type. There are also designations with a slash, such as NU10/500(M), where the number after the slash corresponds to the bore diameter in millimeters. Send the full part number and we'll quote it.

In Argentine industry these bearings are found in gearboxes, centrifugal pumps, industrial fans, rolling mills, mills and power transmission equipment. Also in machine tools and conveyors where the shaft works under high radial load and needs freedom for expansion. Because it has no flanges on the inner ring, the NU series allows relative axial displacement between shaft and housing, which simplifies assembly in two-support arrangements with one fixed and one floating bearing.

To select correctly, take into account the radial load, the rotation speed and the internal clearance the assembly needs. Lubrication can be grease or oil depending on the operating conditions and temperature; in critical applications it is advisable to define the cage type and sealing. Assembly requires cleanliness, alignment of the supports and correct adjustment of the shaft and housing. If the bearing works under axial load, consider combining it with another arrangement or consult the appropriate alternative.

Cross-references between brands are handled by designation system and dimensions: an NU code from another brand may correspond to the same size and arrangement, but it is advisable to verify the cage, clearance and tolerances before replacing. If you bring the original part number or an unidentified sample, at MR Accesorios Industriales we'll tell you the compatible alternative and quote it.
