The NSK EM series ball screw is a linear transmission component that converts rotation into axial displacement with high efficiency and repeatability. It is used in machine tools, machining centers, automation equipment and systems that require precise positioning. MR Accesorios Industriales sells this line for plants and workshops in Argentina that need spare parts or components for their linear axes.
The EM series designation is read by nominal diameter, lead and number of ball circuits. For example, EM2812-3E indicates a screw with a 28 mm diameter and 12 mm lead with 3 circuits; EM4016-4E combines a 40 mm diameter with a 16 mm lead and 4 circuits. The suffix E identifies the standard execution of the series. These part numbers allow you to select the screw according to the required load and speed.
In Argentine industry, NSK EM series ball screws are used in milling machines, CNC lathes, grinding machines, machining centers and automation equipment. They are also used in presses, manipulators and precision conveying systems. Their ability to withstand high axial loads with low friction makes them suitable for intensive duty cycles and repeatability requirements in production.
To select the right screw, take into account the axial load, rotation speed, rigidity and required precision. Installation requires aligning the supports with the nut axis and controlling axial play. Proper lubrication and sealing against contaminants extend service life. In high-speed applications, check the critical speed and the cooling system. The nut must be firmly fastened to the carriage to prevent vibration.
NSK EM series ball screws can be interchanged with equivalent products from other brands, as long as the diameter, lead, number of circuits and nut type match. When replacing a screw, compare the mounting dimensions and load capacity. If the original part number is not available, the part can be identified by its measurements and functional characteristics in order to offer a compatible alternative.
To request a quote for the NSK EM series ball screw you need, send the complete part number by WhatsApp to MR Accesorios Industriales. If you do not have it on hand, send us the main measurements or a photo of the part and we will tell you which option applies. We will reply promptly with the information so you can move forward with your project.
