The "twisted coil spring" is a spring that receives a torsional moment around the coil's central axis. There are cases where it is used by winding it in and cases where it is used by unwinding it, but generally, it is used in the winding direction. When subjected to a load, the coil diameter changes significantly. It is necessary to allow some space with the mounting components. 【Features】 ■ Piano wire ■ A spring that receives a torsional moment around the coil's central axis ■ Generally used in the winding direction ■ The coil diameter changes significantly when subjected to a load ■ It is necessary to allow some space with the mounting components *For more details, please refer to the PDF document or feel free to contact us.

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 continuous winding and closed ends with a seat winding to make the end face flat. Generally, the end faces are ground flat to prevent load bias and damage to mating parts. For those with a small wire diameter (thin wire), grinding may be omitted as they have less impact on load bias and mating parts. 【Features】 ■ Zinc-plated piano wire ■ Spring that receives load at the center of the coil ■ Available in open end and closed end ■ Prevents load bias and damage to mating parts *For more details, please refer to the PDF document or feel free to contact us.

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.

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 shape can be either an open end with no winding or a closed end with a seat winding to make the end face flat. Generally, the end face is ground flat to prevent load bias and damage to the 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】 ■ Made of stainless steel ■ A spring that receives load at the center of the coil ■ Available in open end and closed end ■ Prevents load bias and damage to mating parts *For more details, please refer to the PDF document or feel free to contact us.

This technical document provides fundamental knowledge about springs, including key points to consider when selecting springs, an overview of four types of springs, and information on allowable ranges and allowable stress. It presents insights that can only be gained from "Sotec," which handles over 13,300 types of springs. 【Contents (partial introduction)】 ■ Important things to know (about winding direction, number of coils, sagging, etc.) ■ Overview of each spring (compression coil springs, tension coil springs, torsion coil springs) ■ Reference materials (tolerances, tensile strength, allowable stress, etc.) 　and more *For more details, please refer to the technical document or feel free to contact us.

Sotec Corporation has been selling standard springs under the "TRYspring" brand for over 20 years. At the start of sales, there were two types of springs: compression springs and tension springs, totaling 2,929 items. In response to customer demands, we have now added torsion springs, close-tolerance springs, and circlips, bringing the total to over 13,300 items across five types. This catalog introduces various springs, including "compression coil springs," which bear loads at the center of the coil, and "tension coil springs," which bear loads in the opposite direction of compression springs. Additionally, we also feature "torsion coil springs" and "circlips."

The "twisted coil spring" is a spring that receives a twisting moment around the coil's central axis. There are cases where it is used by winding it in or unwinding it, but generally, it is used in the winding direction. When a load is applied, the coil diameter changes significantly. It is necessary to allow some space with the mounting components. 【Features】 ■ Made of stainless steel ■ A spring that receives a twisting moment around the coil's central axis ■ Generally used in the winding direction ■ The coil diameter changes significantly when a load is applied ■ It is necessary to allow some space with the mounting components *For more details, please refer to the PDF document or feel free to contact us.
