SKF NUP ECMA series cylindrical roller bearings are high load capacity radial bearings, designed for shafts where loads are high and precise axial guidance is required. They are used in gearboxes, reduction units, rolling mills, pumps and power transmission equipment. At MR Accesorios Industriales we sell and distribute SKF in Buenos Aires, Argentina, and we quote the exact part number you need by WhatsApp.

The designation of this series is read in parts: the letters NUP identify the cylindrical roller bearing type, the number that follows is the series and bore number, and the ECMA block accompanies the execution. In the series examples, two-digit codes such as NUP 236 ECMA, NUP 238 ECMA, NUP 240 ECMA and NUP 244 ECMA coexist with four-digit codes such as NUP 2324 ECMA, NUP 2326 ECMA, NUP 2328 ECMA and NUP 2330 ECMA. To request a quote, send us the complete part number exactly as it appears on the drawing or on the part.

This type of bearing is chosen in applications where the shaft works with high radial loads and moderate speeds: gearboxes and reduction units, rolling mills and rolling trains, industrial pumps, paper machines, mining equipment and power transmission in manufacturing plants. In the Argentine market they are found in heavy equipment maintenance, steel mills, cement plants and continuous process plants, where the robustness of the cylindrical roller and the axial guidance of the NUP design make the difference compared with other configurations.

To select the correct bearing, take into account the radial and axial load the shaft will support, the rotation speed, the type of housing and the mounting method. Alignment between shaft and housing is key: excessive misalignment shortens bearing life. Lubrication must be chosen according to the operating regime and the environment, and mounting is done with the right tools so as not to damage raceways or rollers. If the equipment comes from a repair, it is advisable to check the condition of the shaft and the housing before fitting the new part.

Cylindrical roller bearings are identified by their designation and their main dimensions, and the different brands on the market use their own nomenclature. When the customer brings a part number from another brand or an unidentified part, at MR Accesorios Industriales we indicate the compatible alternative according to dimensions and configuration. Interchangeability between brands is resolved by comparing series, dimensions and execution, not just the commercial part number.

If you need a bearing from the NUP ECMA series, send us the part number or model by WhatsApp to MR Accesorios Industriales and we will quote it shortly. We can also advise you on the variant that best suits your equipment according to the working conditions.
