Methods for Addressing Lead Screw Noise

Category： Industry News

Release time：2026-06-08

Compared with sliding screw assemblies, the driving torque is reduced to one-third. Moreover, because the trapezoidal‑threaded screw and its nut are supported by numerous rolling balls that roll continuously, the system achieves higher motion efficiency. Compared with earlier sliding screw assemblies, the required driving torque is less than one-third, meaning that achieving the same motion performance demands only one-third of the power needed when using a rolling‑element screw assembly. This results in significant energy savings.

Methods for addressing lead screw noise:

1. Compared with sliding screw assemblies, the driving torque is reduced to one-third. Thanks to the numerous balls rolling between the screw shaft and the nut in trapezoidal‑threaded screws, higher motion efficiency can be achieved. Compared with conventional sliding screw assemblies, the required driving torque is less than one-third; in other words, achieving the same motion performance requires only one-third of the power needed when using a rolling screw assembly. This results in significant energy savings.

2. Guaranteed high precision: The ball screw assemblies are manufactured using world‑class machinery made in Japan. In particular, the factory environments for grinding, assembly, and inspection are subject to stringent control of temperature and humidity. Thanks to a robust quality‑management system, precision is fully assured.

3. Micro‑feed is feasible; since ball screw assemblies utilize rolling‑element motion, they exhibit extremely low driving torque and do not suffer from the stick‑slip phenomena typical of sliding mechanisms, thereby ensuring precise micro‑feed performance.

4. With no backlash and high rigidity, ball screw assemblies can be preloaded. This preload enables the axial clearance to become negative, thereby achieving greater stiffness (by applying preload to the balls within the ball screw; in practical applications such as machine tools, the repulsive force between the balls enhances the stiffness of the nut assembly).

5. High-speed feed is feasible; due to its high motion power and low heat generation, the ball screw can achieve high-speed feed (motion).

Ball screw types typically employ two common recirculation methods: external recirculation and internal recirculation. When the balls lose contact with the screw shaft during the recirculation process, it is referred to as external recirculation; when they remain in continuous contact with the screw shaft, it is called internal recirculation. Each closed loop of the ball circulation is termed a “row,” and the number of leads contained within each row is known as the “number of turns.” In internally recirculated ball screw assemblies, nuts may feature 2‑row, 3‑row, 4‑row, or 5‑row configurations, with each row comprising only a single turn. In externally recirculated designs, each row may have 1.5 turns, 2.5 turns, or 3.5 turns.
