Torsion Springs（Inner Dia. ID：Ø4）

Torsion springs are a type of wire spring. They are springs that receive a twisting moment around the coil. The shape of torsion spring ends is determined by the mounting location and method, enabling selection of 90-, 135- or 180-degree arm angles. Unlike compression springs and tension springs, torsion springs can reduce the design space and labor. Torsion springs can be classified primarily into close-wound and pitch-wound types. When selecting a torsion spring, it's important to carefully check the free length, average coil diameter and spring constant to select the right model for the usage environment or application. But when selecting models, note that different manufacturers define free length differently.

Torsion Spring

ACCURATE

[Features]
- Coil diameter is managed and defined on the basis of the internal support rod diameter.
- Twist the torsion spring in the winding direction.
- Coil diameter decreases when the spring is twisted in the winding direction, so about 90% of the maximum load is generally applied to the guide rod (preventing the spring from toppling).
- In this specifications, the spring constant is calculated with an arm length 1/2 and a free angle B (135°). The allowable displacement is premised on the stress of static load.
- Since the torsion spring varies in load with the partner parts, please use the spring constant as a reference.

■ New specifications
For left-hand winding
- Conventional winding direction changed to left-hand winding.
*TL only goes in the start of the conventional model number.
