{"product_id":"gears-set-of-300","title":"Gears, Set of 300","description":"First-hand experiences with wheels, gears, pulleys and cams are an important part of design technology and STEM education. SI offers an assortment of these materials designed to work with either 3 mm BBQ skewers or 3\/16\" dowels. Gear sets offer 40-, 30- and 20-tooth gears with 3\/16\" bore to accommodate the most popular dowel size, and a 12-tooth gear with a push-fit to 2 mm motor shafts. Three inserts are provided on each sprue, allowing the 3\/16\" bore to reduce to 3 mm. Gears are beveled for 90° meshing. The 40-tooth gear has an additional hole to create an eccentric movement, or to use with a crank handle. Assorted colors.","brand":"SI Manufacturing","offers":[{"title":"Default Title","offer_id":49961226109205,"sku":"SI50001","price":64.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/50001.jpg?v=1781065834","url":"https:\/\/unitedsupplycorp.com\/products\/gears-set-of-300","provider":"United Supply Corp.","version":"1.0","type":"link"}
