The adapter accommodates shaft sizes of 1\/2 inch, 5\/8 inch, 3\/4 inch, or 7\/8 inch, making it versatile across a range of bench grinders and pedestal grinders. The adapter body spans 1 inch in length with a 1\/2-inch width profile. At 0.14 pounds, it is a lightweight but purpose-built component used by maintenance technicians, metalworkers, and grinding equipment operators to match wheel bore to available shaft diameter without swapping out wheels.\u003c\/p\u003e\n\u003cp\u003eThis adapter is used in workshop and industrial settings where abrasive wheels with a 1-inch bore need to be fitted to grinders with shaft diameters smaller than 1 inch. Typical applications include bench grinder retrofits and equipment where shaft and wheel bore sizes do not match from the factory. The adapter is sold as a set and is intended for use alongside flat or cupped washers with a diameter equal to 1\/3 the diameter of the wheel to provide proper side support and safe wheel retention.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTelescoping design fits shaft diameters of 1\/2 inch, 5\/8 inch, 3\/4 inch, and 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003eReduces standard 1-inch wheel bore to smaller shaft sizes in a single adapter set\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003eIntended for use with flat or cupped washers sized at 1\/3 the wheel diameter for side support\u003c\/li\u003e\n  \u003cli\u003eSold as a set with a minimum order quantity of one\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement adapter for bench grinders and pedestal grinders that use abrasive wheels with a 1-inch bore and require mounting on shafts ranging from 1\/2 inch to 7\/8 inch in diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with abrasive wheel mounting safety requirements. Always power down and disconnect the grinder from its power source before removing or installing any wheel components. Follow ANSI B7.1 safety standards for the mounting and use of abrasive wheels, including the use of proper blotter washers and side flanges. Do not overtighten the spindle nut beyond the manufacturer-recommended hand-plus-wrench procedure to avoid wheel stress.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Bore Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter Compatibility\u003c\/strong\u003e: 1\/2 inch, 5\/8 inch, 3\/4 inch, 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdapter Width\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Set\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00048011168593\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000120785\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346348179762,"sku":"7000120785","price":35.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310521971.jpg?v=1782078043","url":"https:\/\/voomisupply.com\/products\/3m-7000120785-telescoping-flange-adapter-1-in-wheel-shaft","provider":"Voomi Supply","version":"1.0","type":"link"}
