The sheave accepts an H-style quick-detach bushing, allowing for rapid installation and removal without specialty tooling. The outside diameter measures 6.75 inches, with a belt pitch A diameter of 6.0 inches and a belt pitch B diameter of 6.4 inches. Bore diameter is field-configurable from 0.375 inches to 1.5 inches depending on the bushing selected. Weighing 5.45 pounds, this sheave suits applications where reliable belt-driven power transfer is required. Licensed trades and mechanical contractors install this component during drive system assembly, replacement, or redesign.\u003c\/p\u003e\n\u003cp\u003eThis sheave is used in belt-drive assemblies found in residential and commercial HVAC air handlers, blower systems, cooling towers, pumps, and general industrial machinery. The two-groove configuration supports dual A-section or B-section V-belts running in parallel, making it appropriate for higher-torque or redundant-drive setups. The H-style QD bushing interface is a widely used standard in split-taper bushing systems, simplifying shaft fitment across a range of bore sizes within the specified min-max range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-groove design supports dual A-section or B-section V-belt configurations\u003c\/li\u003e\n  \u003cli\u003eQD H-style bushing mount allows fast installation and removal with standard hand tools\u003c\/li\u003e\n  \u003cli\u003eBore diameter adjustable from 0.375 inches to 1.5 inches via H-style bushing selection\u003c\/li\u003e\n  \u003cli\u003e6.75 inch outside diameter with 6.0 inch belt pitch A diameter and 6.4 inch belt pitch B diameter\u003c\/li\u003e\n  \u003cli\u003eWeighs 5.45 pounds for straightforward handling during installation\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31171804 for procurement and catalog classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install sheave for belt-drive systems requiring an H-style QD bushed, two-groove V-belt sheave with a 6.75 inch outside diameter.

Always de-energize and lock out the drive system before removing or installing sheaves, per OSHA lockout\/tagout procedures. Ensure the mating QD H-style bushing is correctly torqued per the bushing manufacturer specifications before running the drive. Verify belt alignment and tension after installation to prevent premature wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch A Diameter\u003c\/strong\u003e: 6.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch B Diameter\u003c\/strong\u003e: 6.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: H (QD Quick-Detach)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171804\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: BROWNING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1043090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51541772108082,"sku":"1043090","price":225.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68a6075b8a0e58acc117948d5041935e.jpg?v=1785884627","url":"https:\/\/voomisupply.com\/products\/browning-1043090-2bk70h-qd-bushed-v-belt-sheave-2-groove","provider":"Voomi Supply","version":"1.0","type":"link"}
