Introduction of piano wire compression coil springs that bear loads at the center of the coil.
The "compression coil spring" is referred to as a "compression spring" and is a spring that receives load at the center of the coil. The end face shapes include open ends with uncoiled ends and closed ends with a seat coil that makes the end face flat. Generally, the end faces are ground to make them flat to prevent load bias and damage to mating parts. For springs with a small wire diameter (thin wire), grinding may be omitted as they have less impact on load bias and the mating parts. 【Features】 ■ Piano wire ■ A spring that receives load at the center of the coil ■ Available in open ends and closed ends ■ Prevents load bias and damage to mating parts *For more details, please refer to the PDF document or feel free to contact us.
