These roller chain connecting links with bent ear are engineered for mechanics, maintenance technicians, and DIY builders who need a reliable, drop-in replacement that installs fast and holds under load.\u003c\/p\u003e\n\u003cp\u003eEach link is machined from carbon steel and is available in four standard chain series — 08B, 10A, 12A, and 16A — with four configuration options per series: single-side single hole, single-side double hole, double-side single hole, and double-side double hole. The bent ear (also called a bent plate or locking tab) secures the spring clip in place, preventing accidental disengagement during operation. Link dimensions conform to ISO\/ANSI roller chain standards; pitch ranges from approximately 12.7 mm (1\/2 in) for 08B up to 25.4 mm (1 in) for 16A.\u003c\/p\u003e\n\u003cp\u003eTypical applications include roller chain repair on conveyor systems, agricultural machinery drive chains, industrial power transmission equipment, and go-kart or small engine drive setups requiring a standard connecting link with positive retention.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard ISO\/ANSI roller chains — 08B (ISO), 10A (ANSI #50), 12A (ANSI #60), 16A (ANSI #80).
