We have started selling the 'MSW-XS' by utilizing the know-how we have cultivated in spring products so far. * A document summarizing features and details is available for download exclusively for Ipros members. The 'MSW-XS' is an improved product based on the most successful "S-shaped spring" in the sliding door market. By reducing the torque gradient, we have made it possible to achieve a higher rotation speed more efficiently, and by revising the design, we have reduced output loss. Additionally, we have realized miniaturization and cost reduction, and improved grease leakage. With the introduction of the 'MSW-XS', we expect to provide new options for the design of sliding door products such as semi-automatic doors and elevator doors. [Features] - Four standard output types ranging from 2.45 to 9.8N - The direction of the cord pull can be selected from three options - There are two mounting surfaces, allowing for versatile use depending on the application - Environmental impact is reduced due to improvements in grease leakage - In the future, we plan to release a unique design output adjustment mechanism (optional) * You can view the catalog via "PDF Download."

At Sanko Spring Co., Ltd., we can manufacture constant variable load type and reverse variable load type specifications. Please feel free to contact us. The springs are designed to exert a strong force when the number of products is high and a weaker force when the number decreases. The lamp cord becomes stronger as it stretches, trying to return to its original shape, so the spring force is gradually weakened to balance the lighting fixtures at any height. For more details, please contact us or refer to our catalog.
