Specifically engineered for the massive walking foot systems of the Seiko SK-2B, SK-6, and SK-6F, this high-tension spring is the primary engine of your machine's downward force.The Powerhouse of Heavy-Duty FeedingIn the ultra-heavy-duty world of the Seiko SK series, the outer presser bar spring must provide immense, constant pressure to keep thick leathers, multi-layered webbing, and heavy canvas from shifting during the needle's penetration. The 1407 / 97742 spring is designed to maintain its structural memory under extreme compression, ensuring that the walking foot assembly grips the material firmly for every single stitch.Key Features & BenefitsHigh-Memory Chrome Silicon Steel: Manufactured from premium tempered alloy to resist "sagging" or losing tension, even after millions of high-impact cycles on dense materials.Heavy-Gauge Industrial Tension: Specifically calibrated to handle the extreme downward force required to sew through 10mm+ of saddle leather or industrial webbing.Vibration-Dampening Design: Engineered to absorb the mechanical harmonics of the SK series' massive punching power, preventing "foot bounce" at higher speeds.Uniform Compression: Precision-wound coils ensure a perfectly vertical force distribution, preventing the presser bar from tilting or causing uneven feeding.Machine CompatibilityThis Outer Presser Bar Spring is a primary replacement part for the following Seiko extra-heavy-duty models:Seiko SK-2B (Cylinder Bed)Seiko SK-6 (Flatbed)Seiko SK-6F (Flatbed with Reverse)Also compatible with other industrial heavy-duty machines utilizing the 1407 / 97742 spring standard.Product SpecificationsFeatureDetailsPart Number1407 (Interchangeable with 97742)Component TypeOuter Presser Bar Tension SpringMaterialHardened Tempered Spring SteelApplicationExtra-Heavy-Duty Walking Foot SystemsMaintenance Insight: If you notice your material "slipping" or the stitch length varying when crossing thick seams, your 1407 spring may have fatigued over time.
