The product has no set standard and is used where a rotating joint enables free rotation and reduces the impact of torsional forces. The dual-eye construction provides a secure and stable connection. The AISI 316 design provides excellent resistance to corrosion in marine and chemically demanding environments.\u003c\/p\u003e\n\u003ch2\u003eAREA OF USE\u003c\/h2\u003e\n\u003cp\u003eThe product is used in marine environments, mooring, load lashing, rigging, and cable suspension. It is intended for applications where rotating movements occur and where it is necessary to prevent ropes, wires, or chains from twisting, which reduces wear and increases operational reliability under load.\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL SPECIFICATIONS\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eProduct type:\u003c\/strong\u003e Swivel\u003cbr\u003e\u003cstrong\u003eProduct family:\u003c\/strong\u003e Eye-to-eye\u003cbr\u003e\u003cstrong\u003eMaterial class:\u003c\/strong\u003e A4\u003cbr\u003e\u003cstrong\u003eStrength class:\u003c\/strong\u003e Not specified\u003cbr\u003e\u003cstrong\u003eArticle number:\u003c\/strong\u003e M8254\u003cbr\u003e\u003cstrong\u003eStandard:\u003c\/strong\u003e No established standard – not intended for lifting\u003cbr\u003e\u003cstrong\u003eDesign:\u003c\/strong\u003e Double eye with rotating joint\u003cbr\u003e\u003cstrong\u003eSurface finish:\u003c\/strong\u003e Untreated\u003cbr\u003e\u003cstrong\u003eEnvironment:\u003c\/strong\u003e Marine\u003cbr\u003e\u003cstrong\u003eDelivery unit:\u003c\/strong\u003e Piece\u003c\/p\u003e\n\u003ch2\u003eFREQUENTLY ASKED QUESTIONS (FAQ)\u003c\/h2\u003e\n\u003ch3\u003eWhat is the primary function of a dual-eye (eye-to-eye) swivel?\u003c\/h3\u003e\n\u003cp\u003eA swivel allows for free 360° rotation between two connected points in a screw, wire, or chain assembly:\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eEliminates torsional forces:\u003c\/b\u003e Prevents ropes, chains, anchor chains, and steel wires from twisting, knotting, or unravelling when under load or moving.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eReduces wear and fatigue:\u003c\/b\u003e By absorbing torque, connected components are relieved of harmful off-axis loads, which significantly extends the service life of both rope and metal rigging.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eSymmetrical and secure connection:\u003c\/b\u003e The two closed eyes provide a permanent, rigid, and symmetrical connection point where you can easily attach shackles, carabiners, quick links, or spliced ropes.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eWhy is acid-proof stainless steel A4 (AISI 316) crucial for rotating swivels?\u003c\/h3\u003e\n\u003cp\u003eRotating components are particularly sensitive to corrosion because the slightest rust on the internal sliding surfaces can cause the swivel to seize:\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eMaximum corrosion protection:\u003c\/b\u003e A4 steel (1.4401 \/ AISI 316) is alloyed with molybdenum, which prevents crevice and pitting corrosion from continuous exposure to saltwater, spray, chlorine, and chemicals.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eGuaranteed rotation over time:\u003c\/b\u003e Unlike simpler materials, the internal contact surfaces will not rust together, ensuring the swivel function is maintained even during prolonged submersion in water.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eHigh toughness:\u003c\/b\u003e Can withstand heavy, dynamic jerks and load variations without the risk of brittle fracture.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eHow is a dual-eye swivel safely installed?\u003c\/h3\u003e\n\u003col start=\"1\"\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eConnection with shackles:\u003c\/b\u003e Since the eyes are closed, the swivel is usually connected using acid-proof D-shackles, lifting shackles, or A4 quick links.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eStraight line of pull:\u003c\/b\u003e Ensure the swivel is always loaded in a straight longitudinal direction.
