Product Description
Meets standard dimensions for D series (compliant with DIN 2098).
This is a cylindrical tensile coil spring with a wire that has been converted to the stainless steel used in springs.
Product Specifications
| Winding direction | Right-handed or left-handed depending on the convenience of the manufacturing machine |
|---|---|
| End Shapes | Reverse Hook |
| Outer Diameter | Based on JIS B2704-3 cold rolled extension coil spring coil diameter tolerance Class 2 |
| Custom length | It is used as a reference value and does not allow for tolerance |
| Allowable load (N) | Based on JIS B2704-3 cold rolled extension coil spring load tolerance at the specified length Class 2 |
| Spring constant | It is used as a reference value and does not allow for tolerance |
| Initial tension | It is used as a reference value and does not allow for tolerance |
| Low temperature annealing | After spring forming, low temperature annealing is applied to improve performance |
| Operating temperature limit | -30°C to +200°C |
| Spring lifespan | The allowable load is displayed as a guide for use. This is calculated based on the allowable torsional stress of approx. 64% with reference to JIS B2704, but it does not mean that the lifespan is guaranteed. For the spring, please select an appropriate load that is less than or equal to this allowable load, considering the required number of repetitions (lifespan) from the relationship between the upper limit stress and the lower limit stress in use.
