For precise linear positioning in machine tools and automation systems, the NSK RNFCL ball screw series delivers efficient conversion of rotation into axial travel. Its recirculating ball design minimizes friction, enabling smooth operation at elevated speeds. MR Industrial Accessories supplies this series to maintenance and purchasing teams throughout the United States and Latin America.

Reading an RNFCL part number is straightforward once you know the pattern. The letters denote the NSK ball screw family. The first two digits after the letters give the nominal shaft diameter in millimeters; the next two digits indicate the lead, also in millimeters. For instance, RNFCL 1520A3S has a 15 mm shaft and a 20 mm lead, while RNFCL 1616A3S has a 16 mm shaft and a 16 mm lead. The alphanumeric block that follows (such as A3 or A6) specifies the nut type and preload, and a trailing S means the nut is sealed.

These ball screws are common in machining centers, CNC mills, grinders, measuring equipment, and automation systems. They also appear in laser cutters, industrial 3D printers, and laboratory positioning devices. Their capacity to handle axial loads while holding precision makes them appropriate where displacement error must stay minimal.

When specifying a ball screw, consider axial load, rotational speed, overall length, and mounting configuration. Preload, shown by the A2, A3, or A6 suffix, influences rigidity and axial play: higher preload increases rigidity but also friction. The S seal keeps contaminants out and lubricant in. Proper alignment of supports with the shaft and use of the recommended lubricant are critical during installation. Careful mounting helps maintain repeatability and extends service life.

NSK RNFCL ball screws can be interchanged with equivalent products from other manufacturers if diameter, lead, nut type, and preload correspond. If you have a code from another brand or an unidentified part, provide the dimensions and characteristics, and we will identify a compatible alternative. MR Industrial Accessories quotes the exact code or size you need.

To request a quote, send the complete ball screw code, for example RNFCL 2020A3S, via WhatsApp or email. Alternatively, provide the main dimensions: diameter, lead, length, and nut type. With that information, our team will respond promptly and help you choose the best option for your equipment.
