THK LM Shafts and LM Shaft End Support

THK LM Shafts are precision-ground cylindrical shafts designed for use with THK’s linear bushing and guide ball bushing lines, providing the hardened raceway surface those products roll against. The LM Shaft End Support (Model SF and Model SK) is a lightweight aluminum fulcrum that secures an LM shaft’s end without requiring the shaft itself to be machined, simplifying mounting to a table or base with bolts or tightening screws. Available across shaft diameters from 3 to 100 mm, they let you build a complete, cost-effective linear guide system by combining shafts, end supports, and a linear or guide ball bushing.
