Long-life ball screw linear actuator replacement
Specifically designed for original equipment manufacturer (OEM) replacement and upgrades of linear modules, KK modules, and precision slides, this product offers a one-stop solution to industry points such as stock shortages, long lead times, and high maintenance costs associated with imported module lead screws.
It achieves 1:1 full-size precision interchangeability, with mounting hole positions, leads, and shaft end dimensions fully compliant with mainstream imported brands. No modifications to equipment structure or program re-tuning are required; replacement can be completed in just 10 minutes, significantly reducing production line downtime.
Performance is fully comparable to imported products of the same class, with accuracy grades covering C3-C7, backlash < 0.005mm, repeatability ±0.003mm, and smooth, jam-free operation. Utilizing high-carbon chromium bearing steel with integral quenching and deep cryogenic treatment, wear resistance is improved by 40%, and service life is comparable to original products.
Sufficient stock is available, and customized preload levels, special coatings, and non-standard shaft end machining are supported, making it the preferred solution for rapid upgrades of automated production lines.
