The NKS KH15-J84 is a high-precision, compact linear bushing designed to provide smooth and accurate linear motion along a 15mm shaft. This linear bearing features a stamped steel outer ring and retainer, housing precision steel balls that circulate to minimize friction and ensure high rigidity. Its compact and lightweight design makes it an excellent choice for applications with limited space, such as in automation equipment, measuring instruments, 3D printers, and other small-scale machinery requiring reliable linear guidance.
