Misumi SFAK12-135-F5 Precision Linear Shafting

Misumi SFAK12-135-F5 Precision Linear Shafting is a precision-grade shaft used as the backbone of linear motion assemblies. Identified by the SFAK12-135-F5 designation, this shaft forms the straight, cylindrical element on which linear bearings and carriages travel in automation, robotics, CNC equipment, and other precision-machining setups. Built to enable accurate alignment and repeatable travel, it is part of Misumi's SFAK series, designed to deliver dependable support for high-precision applications where smooth motion and consistent runout are important. Typical use cases include guide-rail-inspired axis stages, automated assembly lines, and small to midsize machine tools that require precise shafting as a motion element. In a system, it contributes to repeatable positioning and stable travel under varying loads and cycles.
