These simplex roller chain half links are designed for cyclists, mechanics, and industrial maintenance technicians who need a dependable crank link that installs quickly and holds under load. Whether you're repairing a bicycle chain or splicing a conveyor run, the right half link makes the difference between downtime and getting back to work.\u003c\/p\u003e\n\u003cp\u003eEach crank link is manufactured from carbon steel with a bushing-style construction, providing the structural integrity needed for demanding applications. Available in five standard ISO\/ANSI sizes — 06B-1 (3\/8\"), 06C-1 (35B), 10A-1 (5\/8\"), 12A-1 (3\/4\"), and 16A-1 (1\") — with pitch dimensions ranging from approximately 9.525 mm (3\/8\") to 25.4 mm (1\"). Sold individually (1PCS), in pairs (2PCS), or in packs of five (5PCS) to suit single repairs or bulk stocking.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include bicycle chain repair and length adjustment, light industrial conveyor maintenance, and agricultural or power-transmission machinery servicing. Long-tail applications such as \"06B roller chain connecting link,\" \"carbon steel half link for bike chain,\" and \"simplex bushing chain crank link replacement\" are all covered by this versatile range.\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 606 \/ ANSI B29.1 simplex roller chains — 06B-1, 06C-1 (35B), 10A-1, 12A-1, and 16A-1 pitch series.
