Tokai Spring Industries, Inc.

Tokai Spring Industries, Inc. has been a leader in the spring manufacturing industry for 80 years. We specialize in the design and production of all types of metal springs, including disc springs, coil springs, leaf springs, conical springs, and spiral springs. Since our founding, we have focused on custom-made, single-order springs, earning a strong reputation and trust across a wide range of industries, including machine tools, energy, and aerospace.

At this year’s JIMTOF, we are excited to introduce our latest innovation: the high-performance i-MC Spring, designed specifically for machining center spindles. The i-MC Spring boasts exceptional longevity and superior balance at high speeds, making it a top choice for high-performance machining centers worldwide, including in Japan, Germany, Switzerland, the United States, Taiwan, and South Korea.

We invite you to visit Tokai Spring’s booth to experience the impressive capabilities of the i-MC Spring firsthand!

Exhibits

■Disc Springs for Machining Center Spindles [i-MC COMPACT]
We’re showcasing the flagship model of our high-performance i-MC spring series, developed for machining center spindles: the i-MC COMPACT. This spring offers exceptional high-speed balance, over 3 times the lifespan of standard disc springs, and 50% more compactness (in spindle length) compared to typical disc springs. We will display the standard 40mm outer diameter model, as well as a newly developed ultra-mini size with a 9.2mm shaft diameter at JIMTOF 2024.

■The World's Largest Coil Spring
At our booth, experience the awe-inspiring “World’s Largest Coil Spring,” a symbol of Tokai Spring. With a wire diameter of 70mm, an outer coil diameter of 600mm, a height of 1200mm, and a weight of 400kg, it’s displayed prominently at our booth entrance. Don’t miss it!
