Features Glossy and High Accuracy: The glossy and high accuracy of the bearing steel ball screw make it more resistant to wear, extending the service life and ensuring and smooth s. High Temperature Resistance: With the ability to withstand higher temperatures in harsh environments, this rolling ball screw kit maintains stability and performance without deformation. Smooth Curve Ball Screw Drive Design: The smooth curve ball screw drive design enhances the work process, making it more smooth, natural, and efficient. Enhanced Movement Efficiency: Compared to sliding screw pairs, the 1204 ball screw with multiple balls between the screw shaft and nut achieves 1/3 driving torque, resulting in higher movement efficiency. Minimal Torsion and Accurate Micro-feed: By utilizing ball rolling motion instead of sliding motion, this ball screw minimizes torsion, eliminates crawling phenomena, and ensures micro-feed s for industrial supplies. Features: 1、Glossy and high accuracy. More resistant to wear, greatly extends the service life of the ball screw. 2、Higher temperature in harsh environments without deformation to insure stability. 3、Smooth curve ball screw drive designer, making the work more smooth and natural. 4、Compared with the sliding screw pair, there are many balls between the screw shaft and the screw nut with a driving torque of 1/3 ball screw, which can obtain higher movement efficiency. 5、Using ball rolling motion instead of sliding motion, the torsion generated is extremely small, there will be no crawling phenomenons like sliding motion, and accurate micro？feed can be ensured. Specification: Condition: Brand New Item Type: Ball Screw Material: Bearing Steel Nominal Diameter: Approx. 12mm/0.5in Nominal Lead: Approx. 4mm/0.2in Steel Ball Diameter: Approx. 2.381mm/0.1in Bead Count: 4 Rigid: 12.5 Kgf/Um Basic Rated Dynamic Load: 593Kgf Basic Rated Static Load: 1129Kgf Package List: 1 x Ball Screw 1 x Nut Holder 1 x Coupling 1 Set of Fixing Base BK End 1 Set of Support Base BF End Note: 1. Model analysis: for example, 1204 screw (the diameter of the screw is 12mm, the lead is 4mm). Means that the moving distance of the screw in one turn is 5mm, which is the same as the meaning of screw pitch.betweendiv>2. Do not turn out the screw nut. After turning out, the steel ball inside will be off the raceway and cannot be put back. It can only be sent to our company for reassembly. Everyone has a different use place and installation position. There is no installation screw. Please understand.between/div> Package List 1 x Ball Screw 1 x Nut Holder 1 x Coupling 1 Set of Fixing Base BK End 1 Set of Support Base BF End
