Each gear includes a central bearing which can be fixed into place using either a push in peg or screw and once tightened up, it will still rotate smoothly. Gear teeth have rounded ends to accommodate easy connection to other gears in a line or even at 90 degrees to each other. Gears come in a variety of different sizes too, promoting some excellent understanding of gear ratios. A gear chain provides scope for moving a turning force from one place to another and a wind handle can be press-fitted to the front of a selected gear to become ‘the driver gear’. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSets include a bumper range of different gears, and every set includes 2 wind-handles.  \u003c\/span\u003e\u003c\/p\u003e","brand":"105-masterkidz","offers":[{"title":"Default Title","offer_id":46170462191844,"sku":"ME24343","price":790.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0405\/6186\/8963\/files\/ME24343_2.jpg?v=1742897332","url":"https:\/\/toylibrary.hk\/zh-hant\/products\/stem-wall-79pcs-gears-and-chain-set","provider":"Me100fun Toy Library","version":"1.0","type":"link"}
