Name: Torsion Spring Materials: 65Mn Spring Steel Surface Treatment: Untreated Product overview A durable torsion spring made from 65Mn spring steel, designed to apply and store rotational torque with reliable return action. The untreated surface keeps profile simple for integration in assemblies where coating is not required. Key benefits - Strong, fatigue-resistant material: 65Mn spring steel provides dependable torque and long service life in repetitive cycling. - Untreated finish: Suitable for assemblies where coating is unnecessary or where dimensions and fit are critical. - Simple, compact torque solution: Adds rotation or hinges return action with minimal parts and straightforward installation. - Consistent performance: Designed to deliver predictable torque and return in standard torsion applications; suitable for various mechanical fittings. Compatibility and use - Works in common torsion spring configurations where space and mounting pins align with your design. - Ideal for replacing worn or missing torsion springs in existing hardware without major redesign. - Size and exact parameters vary by model; refer to product parameters for your specific application. Use scenarios - Hinge return: Cabinet doors, appliance lids, or small cabinet hardware requiring smooth return to a closed or open position. - Latch or catch mechanism: Tool boxes, enclosures, or small devices needing reliable closing action. - Lightweight suspension or counterbalance: Small fixtures or panels that require modest rotational force and reset. Performance notes - Material strength supports repeated cycles with consistent torque. - Untreated surface may require downstream finishing or coatings if environmental protection is needed.
