Springs rotate simultaneously when compressed. When both ends, which rotate the most, are restrained (fixed), resistance such as twisting and kinking occurs, leading to reduced spring performance and lifespan. This product features a thrust bearing on the load surface to eliminate various resistances when the spring is compressed. The contact guide section uses a rotating tornado shaft made of a material with excellent self-lubricating and friction/wear resistance properties. This double smooth effect eliminates resistance and stress, maximizing the spring's performance.
