(Solid Red)
Loads are shown in Newtons.
Efficient Operating Range is 15% to 25% deflection of free length. Maximum deflection is 25%; Long Life deflection is 20%; Optimum Life deflection is 15%. Deflection beyond this Efficient Operating Range could result in premature spring failure. Travel to Solid is a reference dimension only and should never be approached during use.
