We would like to introduce our "TSK Resin Sliding Screw." We have adopted a highly lubricative resin material for the nut part, and the rolling shaft 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 similar to ball screws. 【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, achieving shorter delivery times through standardization ■ We can accommodate additional processing of the screw shaft end on a short delivery basis according to your requests *For more details, please refer to the PDF materials or feel free to contact us.
