A 60T pulley is the large end of a belt reduction — running it against a smaller 16T or 20T gives a 3:1 or 4:1 speed reduction with a corresponding torque increase, which is exactly how the \u003ca href=\"\/products\/micron-motion-kit\" title=\"Micron Motion Kit\"\u003eMicron Motion Kit\u003c\/a\u003e uses it: four of these 60T pulleys driven by 16T motor pulleys through Gates 2GT belts, to give the Micron its compact, high-torque X\/Y drive.\u003c\/p\u003e\n\u003ch3\u003eWhy this over the alternatives\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo Trees 60T vs. generic 60T\u003c\/strong\u003e — Two Trees spec is what the Micron motion system was designed around; the bore tolerance and grub-screw depth are clean.

If you want a non-driven tensioner wheel, use an idler pulley (the teeth aren't load-bearing on an idler, but the toothed profile keeps the belt path consistent). Also not a T5 \/ HTD \/ MXL pulley — the tooth profile doesn't interchange, and the Micron motion system is GT2 throughout.\u003c\/p\u003e","brand":"Two Trees","offers":[{"title":"Default Title","offer_id":42423298687198,"sku":"9491331169","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/9767\/0313\/products\/Untitled46.png?v=1643862294","url":"https:\/\/formosissima.myshopify.com\/products\/60t-bore-5-width-6-pulley","provider":"dfh.fm","version":"1.0","type":"link"}
