Compact high-force spring — precise dimensions for reliable fit and performance Key benefits High force in a small package: delivers a maximum force of approximately 12 kg, providing strong return or load support where space is limited. Predictable, repeatable performance: fixed dimensions (outer diameter, wire thickness, and length) make it easy to select and replace springs with consistent behavior. Simple compatibility check: clearly stated measurements allow quick verification against device requirements and housings. Important specifications Maximum force: approx. 12 kg Outer diameter: 12 mm Wire diameter: 2 mm Free length: 45 mm Why you need this spring Provides substantial compression/load capacity without taking up much space, useful when a compact, sturdy spring is required. The 2 mm wire thickness offers robustness and resistance to deformation under moderate loads. Exact dimensions minimize trial-and-error during repairs or custom builds. Compatibility and fit guidance Intended for applications that accept a spring with a 12 mm outer diameter and 45 mm free length. Confirm internal bore and seat clearances before installation. Wire diameter of 2 mm suits assemblies that require a more rigid spring than thin-wire variants. Check intended load and travel to ensure the spring’s maximum force (~12 kg) aligns with your application. Practical use scenarios Replacement spring for small mechanical assemblies or appliances that require a compact, strong return spring. Component for DIY projects, fixtures, or prototypes where a clearly specified spring dimension and force are needed. Retrofit or repair use in equipment where space constraints demand a 12 mm outer diameter spring with substantial load capacity. Installation tips Verify dimensional clearance and seating surfaces before fitting. Compress and install gradually, checking alignment to avoid side loading. Match spring force to application requirements; where precise force curves are critical, test under operating conditions. Specifications above reflect the product measurements and performance: maximum force ~12 kg, outer diameter 12 mm, wire diameter 2 mm, length 45 mm.
