Made in the U.S.A., NB’s shafts are never annealed, so outer diameters are ultra precise — tolerances are always reliable. Tapped shafts can be ordered with one or both ends tapped, in either case-hardened carbon steel or stainless steel. Threaded shafts can be ordered with one or both ends threaded, in case-hardened carbon steel. Diameters […]
Ball + roller guides
What’s the difference between dynamic load capacity and static load capacity?
Rolling element linear bearings, such as round shafts and bushings, profiled rail guides, crossed roller slides, and even ball screws, have two load capacity specifications — dynamic load capacity and static load capacity — which are based on different operating parameters and performance criteria and are independent of each other. To accurately size and select a […]
When should you use a ball spline?
A ball spline is a type of rolling bearing linear guide, similar to a round shaft and bushing assembly, but with a critical distinction in its operation. The shaft of a ball spline is much like a linear guide shaft, except that the spline shaft has grooves along its length. The spline nut (analogous to […]

Common applications for linear rails
Linear rails are linear assemblies that have twin parallel tracks containing load-supporting balls or rollers. The backbone of many industrial applications, they provide low-friction guidance and high stiffness for loads that can range from just a few grams to thousands of kilograms. Their variety of sizes, accuracy classes, and preloads make linear rails suitable for […]
