The NSK ball screw support is a precision component mounted at the ends of a ball screw to fix it axially and allow it to rotate with minimal friction. It is used in machine tools, machining centers, automation equipment and linear positioning systems where repeatability and axial rigidity are critical. MR Accesorios Industriales sells this line of NSK supports for the Argentine industrial market.

The designation of these supports is read in blocks. The letters WBK identify the family of ball screw supports. The number that follows indicates the nominal diameter of the shaft or screw it houses: for example, WBK17DF-31H corresponds to a support for a 17 mm screw, WBK20DF-31H for 20 mm, and so on up to WBK40DF-31H for 40 mm. The suffix DF indicates the double-bearing configuration with preload, and the final number 31H distinguishes the fixing and sealing variant. This nomenclature allows you to quickly identify the size and the type of mounting.

These supports are used in applications where the ball screw must be supported with high precision. They are commonly seen in milling machines, CNC lathes, grinding machines, machining centers, coordinate measuring machines and industrial automation equipment. In Argentina, the metalworking, automotive, food and machine tool sectors rely on this line to maintain the accuracy of their linear motion systems. MR Accesorios Industriales supports these sectors with fixing and support solutions.

To select the correct support, take into account the screw diameter, the required type of fixing (fixed side or floating side) and the load and speed conditions. The mounting requires aligning the support with the screw shaft and adjusting the bearing preload according to the manufacturer's specifications. Proper lubrication and sealing against contaminants extend service life. If the screw runs at high speeds, check heat dissipation and the permissible axial clearance.

NSK ball screw supports can be interchanged with those of other brands that follow the same mounting standard and dimensions. When looking for a replacement, compare the shaft diameter, the center height, the distance between holes and the type of fixing. If you have the part number of another brand, send it to us and we will indicate the compatible alternative. We can also quote the exact NSK part number you need.

To move forward with your inquiry, send us on WhatsApp the complete part number of the support, for example WBK25DF-31H, or the screw dimensions and the type of mounting. At MR Accesorios Industriales we will quote it for you promptly and advise you so that you choose the variant that best suits your machine. Every answer is backed.
