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. Reference: JIS B2704-1 Coil Spring - Part 1: Basic calculation method for compression and extension coil springs
