Extension Spring
SAF-Holland

This extension-style spring delivers axial force during extension and functions as a return mechanism in long-travel assemblies. The extension spring stores energy when stretched and provides a restoring force to bring components back to a resting position after actuation. It is used in heavy-duty truck applications where reliable positional control is needed across multiple actuators, brackets and linkages, particularly in systems requiring controlled movement and steady retraction under load. VMRS code 059-001-162 identifies its role within a family of extension springs designed for component-level energy management, while category 42808 places it with similar extension spring variants used in systems demanding robust linear force across travel. Practical considerations include selecting wire diameter, coil count and length to match the intended stroke, load, and fatigue life. Cross references are not listed for this SKU.
