The NSK WBK DFF series ball screw support is a precision component that secures and guides the end of a ball screw in machine tools and automation equipment. Its design with pre-adjusted angular contact bearings withstands axial and radial loads with high rigidity, maintaining screw alignment. It is used in machining centers, CNC lathes, grinding machines and linear positioning systems where repeatability is critical. MR Accesorios Industriales sells this line for the Argentine industrial market.

The WBK DFF series designation reads in blocks: WBK identifies the ball screw support family, the number that follows —35 or 40 in the examples WBK35DFF-31H and WBK40DFF-31H— indicates the shaft diameter for which the mounting is intended, and the DFF suffix defines the sealing and fastening configuration. The final segment -31H corresponds to a construction variant within the series. To select the right support, the screw diameter must be matched with the bearing type and the fastening method required by the application.

In Argentine industry, these supports appear in vertical and horizontal machining centers, numerically controlled lathes, precision grinding machines and high-accuracy positioning tables. They are also used in coordinate measuring equipment, electrical discharge machines and automated handling systems where the ball screw must rotate with minimal vibration and axial deviation. They are common in metalworking, automotive and capital goods plants that work to tight tolerances.

To choose the support, first verify the screw diameter and the bearing type the head accepts. The DFF configuration usually includes sealing that retains lubrication and protects against contaminants, a key aspect in environments with chips or coolant. Mounting requires aligning the support with the screw axis and with the opposite support; any misalignment translates into parasitic load and premature wear. Lubrication must follow the bearing specification and be renewed according to the duty cycle.

NSK ball screw supports can be interchanged with equivalent references from other precision component manufacturers, provided the shaft diameter, bearing type, fastening arrangement and mounting dimensions match. Interchangeability is not automatic: drawings must be compared and the required preload and rigidity verified. If the customer brings another brand's code or an unidentified part, at MR Accesorios Industriales we quote it and indicate the compatible alternative.

To move forward with the quote, send the complete support code on WhatsApp —for example WBK35DFF-31H or WBK40DFF-31H— along with the screw diameter and the machine type. You can also ask about other references in the NSK line or equivalent components. At MR Accesorios Industriales we reply promptly with the technical and commercial information you need for your project.
