The NSK WBK series is a line of ball screw support units that hold the screw end, take the axial load and let it turn with low friction. You will find them on machine tools, machining centers, automation cells and any application that depends on accurate linear movement. MR Industrial Accessories LLC supplies this series to maintenance and purchasing teams in the United States and Latin America.
Reading the code is straightforward once you know the pattern. The letters WBK come first, then two digits for the size, then a suffix that identifies the mounting arrangement. Examples include WBK06-11*, WBK08-11*, WBK10-11, WBK12-11, WBK15-11, WBK20-01, WBK20-11 and WBK25-11. The size digits 06, 08, 10, 12, 15, 20 and 25 relate to screw diameter or load capacity, while -11 and -01 point to different fixing, sealing or preload versions. An asterisk signals that slightly different dimensions exist within that size.
Typical applications cover milling machines, CNC lathes, grinders, machining centers, coordinate measuring equipment, manipulators and high-accuracy positioning systems. In metalworking, automotive and food plants, and among builders of special machinery, these units are common. Their job is to carry the axial and radial loads of the screw so the axis stays rigid and repeats its position.
When you select a support, check the screw diameter, whether fixing is single or double, the sealing needed for the environment (dust, chips, moisture) and the preload required to remove axial play. Installation calls for careful alignment with the linear guide, controlled tightening of the mounting screws and proper lubrication of the internal bearing. Poor mounting can lead to vibration, early wear and lost precision.
NSK WBK supports can be interchanged with units from other makers that share the same dimensional standard, such as THK, HIWIN or SKF, provided the screw diameter, shaft height and mounting interface line up. Send us the original code and we can help you find the equivalent. We work with the exact designation shown on the drawing or on the part.

Frequently asked questions
- What does the -11 suffix mean on a WBK support?
- The -11 suffix identifies a particular mounting and sealing configuration in the WBK series, usually with a square flange and an angular contact bearing. Send us the full code and we will confirm the exact variant.
- How do I choose the right WBK size for my screw?
- Base the choice on the screw diameter and the axial load. The numbers 06, 08, 10, 12, 15, 20 and 25 represent different capacities. Tell us the screw diameter and the machine type, and we will help you select.
- Can you find equivalents from other brands?
- Yes. We can look for an equivalent from another brand that follows the same dimensional standard. Send the original code and the main dimensions, and we will suggest a compatible option or quote the exact code you need.
