nuts at the same time. A well-tensioned eccentric nut paired with a fresh POM wheel eliminates the two most common sources of print artefacts in one go. Wheels should roll smoothly with slight resistance — not loose, not binding. M5 x 25mm bolts are the standard fitment for most Creality and Anycubic gantry positions.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- end pw-wrap --\u003e","brand":"NZN Electronics","offers":[{"title":"Default Title","offer_id":42723039740000,"sku":"3DP-625ZZ-POM-IDLER","price":1.99,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/6127\/0112\/files\/Direct_pan_shot.jpg?v=1777170416"}],"url":"https:\/\/www.nznelectronics.co.nz\/collections\/bearings-wheels.oembed","provider":"NZN Electronics","version":"1.0","type":"link"}
