THK MDK Series Ball Screw (Unfinished Shaft Ends)

The THK MDK Series is a compact precision ball screw designed for smooth and accurate linear motion in space-constrained automation and positioning applications. Featuring a flange-type nut and unfinished shaft ends, it offers flexibility for custom end machining to suit specific mounting configurations and system integration requirements.

Engineered with THK’s precision grinding technology, the MDK Series delivers stable motion, low friction, and reliable load performance in a compact form factor. Its flange-type nut design allows for efficient integration into small machinery while maintaining high positioning accuracy and durability across light to medium-duty applications.

Available models span a range of shaft diameters, leads, and lengths to suit different travel and load requirements. The MDK0601-3G2+150LC7A features a 6mm shaft with 1mm lead at 150mm length, while the MDK0801-3RRGT+92LC5 offers an 8mm shaft with 1mm lead at 92mm length. For higher load and longer travel requirements, the MDK1405-3RRGT+250LC5A and MDK1405-3RRGT+300LC5-A both feature a 14mm shaft with 5mm lead at 250mm and 300mm lengths respectively.
