Because the tracks are elastic, they will maintain tension even if you do not precisely match this distance. However, if the spacing is too short, they will be loose and more likely to slip off; if the spacing is too long, additional strain will be placed on the sprocket shafts, and the motor might not be able to turn as well.\u003c\/p\u003e\n\u003ctable class=\"picture_with_caption center\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003ca class=\"noscript-fallback\" href=\"https:\/\/a.pololu-files.com\/picture\/0J7923.1200.jpg?37dce244c597dd511d72e8941c76b2dd\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\u003cimg class=\"zoomable\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/0J7923_500.jpg\" alt=\"\" data-gallery-pictures='\u0026lt;{\"id\":\"0J7923\",\"caption\":\"\\u003cp\\u003eSprocket spacing diagram for the Pololu 22Tand 30T track sets.\\u003c\/p\\u003e\",\"url_tiny\":\"https:\/\/a.pololu-files.com\/picture\/0J7923.98x98.jpg?37dce244c597dd511d72e8941c76b2dd\",\"url_medium\":\"https:\/\/a.pololu-files.com\/picture\/0J7923.600x480.jpg?37dce244c597dd511d72e8941c76b2dd\",\"url_full\":\"https:\/\/a.pololu-files.com\/picture\/0J7923.1200.jpg?37dce244c597dd511d72e8941c76b2dd\",\"longest_side\":2163}\u0026gt;' data-picture-id=\"0J7923\" data-picture-longest_side=\"2163\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSprocket spacing diagram for the Pololu 22Tand 30T track sets.\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eDocuments\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.pololu.com\/file\/0J1359\/pololu-track-set-dimensions.pdf\"\u003eDimension diagram of the Pololu Track Set\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.pololu.com\/file\/0J1597\/pololu-22t-track-set.step\"\u003e3D model of the Pololu 22T Track Set\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.pololu.com\/file\/0J1598\/pololu-30t-track-set.step\"\u003e3D model of the Pololu 30T Track Set\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pololu","offers":[{"title":"Default Title","offer_id":42291032391871,"sku":"MLE00786","price":900.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/products\/Pololu-30T-Track-Set-Black_4bda9fdc-1162-4df9-a25b-4ba1fdc36490.jpg?v=1735815727","url":"https:\/\/makerlab.ph\/products\/pololu-30t-track-set-black","provider":"Makerlab PH","version":"1.0","type":"link"}
