Feature: 1. Combining glossy surface and high accuracy, it is more resistant to wear, greatly extending the service life of the ball screw, and the service life is increased several times. 2. Higher temperature in harsh environments without deformation to make sure stability. 3. Smoothly curve ball screw drive designer, work more smoothly and naturally. 4. Compared with the sliding screw pair, the driving torsion of the ball screw is 1/3. There are many balls between the screw shaft and the screw nut, which can achieve higher motion efficiency. 5. Because the rolling motion of the ball is used to replace the sliding motion, the torsion generated is extremely small, and there will be no crawling phenomenons like the sliding motion, which can make sure the realization of precise micro‑feed. Specification: Item Type: Rolled Ball Screw SetModel Analysis: For example, 1605 screw rod; (representing that the diameter of the screw rod is 16mm, and the lead is 5mm. It means that the moving distance of the screw rod in one circle is 5mm, which is equivalent to the thread pitch) Technical Index: Nominal Diameter: Approx. 16mm / 0.6in Nominal Lead: Approx. 5mm / 0.2in Steel Ball Diameter: Approx. 3.175mm / 0.1in Material: Bearing steel Oil Hole: M6 Number of Beads: 4 Ball Screw Length: 100mm, 200mm, 250mm, 300mm, 500mm Size: Approx. 100mm / 3.9in 200mm / 7.9in 250mm / 9.8in 300mm / 11.8in 500mm / 19.7in Rigidity: 20Kgf/um Basic Dynamic Load Rating: 780Kgf Basic Static Load Rating: 1790Kgf. Package List: 1 x Ball Screw1 x Nut Seat1 x Coupling1 Set Fixed Seat BK End1 Set Support Seat BF End Note: Do not turn the screw nut out. The steel ball inside will leave the raceway and cannot be reinstalled. It can only be sent to our company for reassembly. Everyone uses different places and installation positions, and there is no installation screw. Please understand, thank you
