{"product_id":"amec-40bs23x1-1-4-h-sprocket","title":"AMEC 40BS23X1-1 4-H Sprocket","description":"\u003cdiv\u003e\u003cp\u003eThe AMEC 40BS23X1-1 4-H Sprocket is a 23-tooth, single-pitch roller chain sprocket designed for ANSI #40 chain. It is part of the 40BS23 family, a bore-to-size (BS) sprocket type that supports a standard through bore and can accommodate a keyed shaft engagement or, in some variants, setscrews for secure mounting. The 23 teeth and 1\/2-inch pitch align with standard #40 roller chain geometry, and the outer diameter of this size is typically about 3.938 inches with a tooth thickness near 0.284 inches. Made from steel, the teeth are commonly non-hardened in catalog variants, suitable for mid-range power transmission applications. Bore options reported across the 40BS23 family include 1\/2 inch, 1-1\/8 inch, and 1-1\/4 inch, enabling a range of shaft sizes while preserving the same 23-tooth geometry and overall sprocket footprint. Depending on the exact variant, configurations may include a through bore with a keyed connection or alternative mounting features to suit different drive systems, all while maintaining compatibility with standard ANSI #40 chain pitch and tooth profile.\u003c\/p\u003e\u003c\/div\u003e","brand":"AMEC","offers":[{"title":"New","offer_id":51659896127790,"sku":null,"price":36.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ac7eb7de-b075-496b-8887-0adc7b030b3f.jpg?v=1769530485","url":"https:\/\/plgautomation.com\/products\/amec-40bs23x1-1-4-h-sprocket","provider":"PLG Automation ","version":"1.0","type":"link"}
