It is compatible with four common belt sections—4L, A, 5L, and B—and uses a replaceable bushing to fit shaft diameters from 3\/8 inch to 1-1\/2 inches, enabling flexible mounting on various shaft sizes and configurations. The durable cast-iron construction provides stiffness and abrasion resistance under heavy loads, while the two-groove geometry supports dual-drive configurations or parallel belt paths without requiring additional pulleys, idlers, or complex alignment. As part of Regal's Browning power-transmission family, the 2BK45H is a standard replacement pulley for industrial equipment, delivering dependable belt engagement and straightforward installation for conveyors, cooling fans, pumps, and other equipment where reliable belt-driven power transfer matters.\u003c\/p\u003e\u003c\/div\u003e","brand":"REGAL","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46285481279722,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-024.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/regal-beloit-2bk45h-sheave","provider":"GTG Hardware","version":"1.0","type":"link"}
