An extension spring’s performance is defined almost entirely by its end hooks and its load rating at a given deflection. The four primary hook types—machine loops, cross-over loops
The correct spring wire diameter is the largest diameter that fits within your space envelope while delivering the required force at your defined deflection, because spring rate sc
The direct answer is that music wire (ASTM A228) typically lasts longer than stainless steel in high-cycle, low-corrosion applications due to its superior tensile strength and fati
To specify a spring correctly on an engineering drawing, you must define the wire diameter, mean coil diameter, free length, number of active coils, spring rate, and material, then
Compression spring load testing verifies that a spring meets its specified force at a defined height or deflection, and the most accurate method is using a calibrated compression t
