C5 Large Lead Rolled Ball Screw for Assembly Line

Assembly lines are the backbone of discrete manufacturing, requiring efficient, precise, and stable linear motion to complete tasks such as sorting, assembling, and conveying. The China C5 Large Lead Rolled Ball Screw for Assembly Line from Maitu serves as the "muscle" of automated assembly systems, responsible for converting rotational motor power into high‑precision linear displacement, directly determining the rhythm and accuracy of the entire assembly line.

Different from general‑purpose ball screws, Maitu’s C5 large lead rolled ball screw is specifically optimized for assembly line scenarios. It adopts advanced cold‑rolling technology to form raceways, which not only enhances surface hardness and wear resistance but also enables a larger lead design (20mm‑100mm). This unique combination allows the assembly line to achieve higher linear speeds at lower motor RPM, significantly shortening cycle times. Meanwhile, the C5 precision grade (lead error ≤0.015mm/300mm) guarantees consistent positioning accuracy for delicate assembly tasks, such as electronic component insertion and part clamping. Our vertical integration manufacturing model ensures strict control over every production process, from raw material selection to final inspection, making this product an ideal choice for high‑efficiency automated assembly lines.
