Threaded M8, it couples the cylinder piston rod to a driven member while allowing angular articulation, accommodating slight misalignment and swinging motion in the load path. Typical uses include clamping, pushing, and pivoting mechanisms on automated equipment where the rod must connect to a moving lever or linkage rather than a fixed point.\u003c\/p\u003e\u003ch2\u003eKJ8D Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSMC\u003c\/td\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eBall Knuckle Joint\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eThread\u003c\/td\u003e\n\u003ctd\u003eM8\u003c\/td\u003e\n\u003ctd\u003eFor Cylinder Series\u003c\/td\u003e\n\u003ctd\u003eC85 Round Body\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCategory\u003c\/td\u003e\n\u003ctd\u003ePneumatics\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cstyle\u003e.ha-2col{display:grid;grid-template-columns:1fr 1fr;gap:44px;margin-top:34px;align-items:start}@media(max-width:768px){.ha-2col{grid-template-columns:1fr;gap:28px}}.ha-xref{display:flex;flex-wrap:wrap;gap:10px;margin:0 0 10px}.ha-xref-item{border:1px solid #e8e8e8;border-left:3px solid #e05a1e;border-radius:8px;padding:9px 16px;background:#fafafa;min-width:150px}.ha-xref-brand{display:block;font-size:11px;font-weight:800;letter-spacing:.6px;text-transform:uppercase;color:#e05a1e}.ha-xref-model{display:block;font-size:14.5px;font-weight:600;color:#1a1a1a;margin-top:2px}.ha-xref-note{font-size:12.5px;color:#777;margin:0}.ha-dl{display:inline-flex;align-items:center;gap:14px;background:#e05a1e;color:#fff!important;text-decoration:none!important;font-weight:700;font-size:15px;line-height:1.2;padding:15px 28px;border-radius:10px;box-shadow:0 3px 12px rgba(224,90,30,.28);transition:transform .16s,box-shadow .16s,background .16s}.ha-dl:hover{background:#c44d18;box-shadow:0 6px 18px rgba(224,90,30,.40);transform:translateY(-2px)}.ha-dl-ic{display:flex;align-items:center;justify-content:center;width:38px;height:38px;background:rgba(255,255,255,.18);border-radius:8px;flex-shrink:0}.ha-dl small{display:block;font-size:11.5px;font-weight:500;opacity:.92;letter-spacing:.3px;margin-top:2px}\u003c\/style\u003e\u003cdiv class=\"ha-2col\"\u003e\u003cdiv class=\"ha-col\"\u003e\n\u003ch2\u003eKJ8D Datasheet \u0026amp; Manual\u003c\/h2\u003e\n\u003ca class=\"ha-dl\" href=\"https:\/\/content2.smcetech.com\/pdf\/C85.pdf\" target=\"_blank\" rel=\"noopener\"\u003e\u003cspan class=\"ha-dl-ic\"\u003e\u003csvg width=\"22\" height=\"22\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"#fff\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003cpath d=\"M21 15v4a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2v-4\"\u003e\u003c\/path\u003e\u003cpolyline points=\"7 10 12 15 17 10\"\u003e\u003c\/polyline\u003e\u003cline x1=\"12\" y1=\"15\" x2=\"12\" y2=\"3\"\u003e\u003c\/line\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003cspan\u003eDownload Datasheet \u0026amp; Manual\u003csmall\u003eSMC KJ8D · PDF · Official SMC document\u003c\/small\u003e\u003c\/span\u003e\u003c\/a\u003e\n\u003c\/div\u003e\u003c\/div\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":48103788544174,"sku":"KJ8D","price":99.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/7221\/5982\/files\/16_04_2026_11_53_13_KJ8D_SMC.png?v=1784196206","url":"https:\/\/hydroair.ae\/products\/kj8d","provider":"HydroAir","version":"1.0","type":"link"}
