We would like to introduce our "TSK Resin Sliding Screw." The nut part is made of a highly lubricative resin material, and the rolling shaft, which is used in conjunction, is made of stainless steel as a standard material, allowing for use without lubrication. This results in a highly corrosion-resistant positioning sliding screw. Additionally, the rolling shaft features the same groove shape design and ultra-precision machining as ball screw shafts, enabling it to be used as a precise positioning screw, just like a ball screw. 【Features】 ■ Achieves a very smooth movement not found in conventional sliding screws ■ Can be used with positioning accuracy equivalent to that of ball screws ■ The smaller outer diameter of the nut compared to ball screws makes it suitable for compact machine design ■ Excellent cost performance and short delivery times achieved through standardization ■ Additional processing of the screw shaft end can be accommodated in a short lead time upon request *For more details, please refer to the PDF document or feel free to contact us.
