THK DSP Series Ball Spline with Integrated Ball Screw

The THK DSP Series combines a ball spline, acting as the linear motion guide, with a ball screw as the driving force, all in one integrated mechanism. This cuts down the installation space needed for separate guide and drive components, while also reducing the effort involved in building and assembling your equipment. Thanks to this combined structure, the DSP Series can transmit high thrust forces while keeping motion smooth and quiet.

These features make it a strong fit for applications that call for high precision and reliability, such as presses, press-fitting machines, and automatic assembly machines. As an example, the DSP30 model has a ball spline shaft diameter of 30mm, a screw shaft diameter of 16mm, and a DN value of 70,000.
