{"product_id":"pololu-ball-caster-with-3-4-metal-ball","title":"Pololu Ball Caster","description":"\u003cp\u003eThis ball caster kit includes a black ABS housing, a metal ball (chose the correct size above), two spacers (1\/16\" and 1\/8\" thick), and two #2 screw sets.\u003c\/p\u003e\n\u003cp\u003eThe total height of the ball caster, 0.83\", 0.53\", or 0.4\", can be increased to about 1\", 0.7\", or 0.6\" respectively using the included spacers. The two included #2 screws can be used to mount the ball caster to your chassis\u003c\/p\u003e\n\u003cp\u003eNote that our ball casters are designed for small robots; they are not intended to bear more than a few pounds. With more weight than this, friction between the ball and the housing will probably keep it from rolling well.\u003c\/p\u003e\n\u003ch2\u003eDimensional Drawing\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/pololu-ball-caster-with-0-750in-metal-ball.pdf?v=1621950785\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e3\/4 inch\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/pololu-ball-caster-with-0-500in-ball.pdf?v=1621950785\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e1\/2 inch\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/pololu-ball-caster-with-0-375in-ball.pdf?v=1621950785\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e3\/8 inch\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pololu","offers":[{"title":"3\/4 inch","offer_id":390424422,"sku":"POL-955","price":3.95,"currency_code":"EUR","in_stock":false},{"title":"1\/2 inch","offer_id":415237741,"sku":"POL-953","price":2.95,"currency_code":"EUR","in_stock":false},{"title":"3\/8 inch","offer_id":39351780573267,"sku":"POL-951","price":2.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/0J9808.1200.jpg?v=1621950871","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/pololu-ball-caster-with-3-4-metal-ball","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
