The "Conston" is a constant load spring that reciprocates with a consistent force, whether pulled or pushed, and regardless of the stroke length. Even with a long stroke, the space required after retraction is only equivalent to one small diameter drum. It can also be converted into rotational force and is compatible with free stop functionality. ★ We are currently offering standard products as samples to the first 50 applicants. You can actually hold it and try out the feel during reciprocation. ★ The video demonstration is available in our showroom. Please contact us if you would like to see it in person. 【Features】 ■ Constant output regardless of stroke length ■ Compact after retraction even with long strokes ■ Possible to design mechanisms and devices utilizing springs ■ Versatile applications depending on installation methods ■ Lifespan and output can be adjusted based on width and diameter * The product catalog has been renewed! We clearly present the features of this product with diagrams and graphs. Please check it out via "PDF Download." Feel free to contact us for inquiries.

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 proven "S-shaped spring" in the sliding door market. By reducing the torque gradient, we have made it possible to achieve a higher rotation rate more efficiently, and by revising the design, we have reduced output loss. Additionally, we have achieved 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 options ranging from 2.45 to 9.8N ■ The direction of the cord pull can be selected from three directions ■ There are two mounting surfaces, allowing for versatile use depending on the application ■ Improved grease leakage reduces environmental impact ■ In the future, we plan to release a unique design output adjustment mechanism (optional) * You can view the catalog from the "PDF Download" section.

Sankou Spring Co., Ltd. is capable of manufacturing constant variable load type and reverse variable load type specifications. Please feel free to contact us. The springs are designed to push strongly when the number of products is high and to push weakly when the number decreases. The curling cord for lighting becomes stronger as it stretches, so to balance the lighting fixtures at any height, the spring force is gradually weakened.
