{"product_id":"pc-c2040-51p-chain","title":"John Deere AA21523 Chain - C2040 X 51 Links","description":"This C2040 planter chain replaces John Deere AA21523 chains and is 51 links long. It is manufactured dimensionally to ANSI B29.1 Standards but features heat-treated components and a high-performance solid roller design. We use a high-quality ANSI roller chain because lower quality roller chains can result in an erratic movement which would cause inconsistent seed spacing. \u003cbr\u003e\u003cbr\u003e\n\u003ch3\u003eAA21523 Specifications\u003c\/h3\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0633\/0187\/7925\/files\/c-type-111_ad08c3f4-6e73-4a1a-a090-e684c5fda1db.png?v=1737624545\" style=\"width: 464px;\" alt=\"John Deere AA21523 Chain - C2040 X 51 Links\"\u003e\u003cbr\u003e\n\u003cul style=\"letter-spacing: normal;\"\u003e\n\u003cli\u003eChain Size: C2040\u003c\/li\u003e\n\u003cli\u003eLength: 51-Links\u003c\/li\u003e\n\u003cli\u003eTensile Strength: 3,970 LBS\u003c\/li\u003e\n\u003cli\u003ePitch (P): 1.000\"\u003c\/li\u003e\n\u003cli\u003eRoller Width (W): 0.312\"\u003c\/li\u003e\n\u003cli\u003eRoller Diameter (R): 0.312\"\u003c\/li\u003e\n\u003cli\u003ePlate Height (H): 0.463\"\u003c\/li\u003e\n\u003cli\u003ePlate Thickness (T): 0.060\"\u003c\/li\u003e\n\u003cli\u003ePin Diameter (D): 0.156\"\u003c\/li\u003e\n\u003cli\u003eOverall Width Including C\/L (F): 0.689\"\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cinline style=\"font-size: 18px;\"\u003e\u003cb\u003eHelpful Tips:\u003c\/b\u003e \u003c\/inline\u003e\u003cbr\u003e\n\u003cul\u003e\n \u003cli\u003eAlways inspect your roller chain before operation\u003c\/li\u003e\n \u003cli\u003eKeep chains well lubricated to ensure optimal performance\u003c\/li\u003e\n \u003cli\u003eNever use a rusted and or stiff roller chain\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e","brand":"USA ROLLER CHAIN","offers":[{"title":"Default Title","offer_id":51715306455407,"sku":"PC-C2040-51P-CHAIN","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/0187\/7925\/files\/CP-C2040-44P-CHAIN-2_5521ccca-d50f-4442-951f-1bf3b125ddad.jpg?v=1756380364","url":"https:\/\/usarollerchain.com\/products\/pc-c2040-51p-chain","provider":"USA ROLLER CHAIN","version":"1.0","type":"link"}
