High strength S-shaped link spring for agricultural machinery
High elasticity and fatigue resistance: High quality 65Mn (65 manganese steel) or 60Si2MnA (silicon manganese steel) spring steel is used, and after scientific heat treatment process (quenching+medium temperature tempering), it obtains extremely high elastic limit, yield strength and fatigue resistance, and can still maintain long-term operation under frequent reciprocating deformation.
Accurate torque output: The S-shaped structure can provide stable and precise torsional torque, ensuring consistent tension or reset force.
Compact and efficient: The S-shaped bending structure achieves a larger effective deformation stroke in a limited space, with flexible installation and saving equipment space.
Double hook end: The hooks (round hook, oblique hook, or irregular hook) carefully designed at both ends come in various forms to ensure a firm and reliable engagement with the agricultural machinery connection point, preventing detachment.
