Belonging to the 700 Series, it uses a 56C (NEMA) input flange and a B5 foot-mount pattern for straightforward installation on conveyors, packaging machinery, and automation assemblies. The gearbox features a 1.8 in center distance and a 0.875 in output shaft diameter with a left-side, solid output shaft, enabling simple drive layouts where space is at a premium. Rated at 0.87 HP, it provides up to 511 in-lb of output torque, making it suitable for moderate-load applications that require precise torque delivery and durable service. Typical uses include material handling, packaging lines, and automated workstations where a compact reducer is paired with a compatible motor that shares the 56C footprint. When selecting this unit, ensure your motor mount matches a 56C flange, and verify alignment of the 0.875 in driven shaft bore with the driven component. The F718-20-B5-G is optimized for single-reduction operation with a 20:1 ratio, balancing a small footprint with solid torque characteristics in industrial gear drives.\u003c\/p\u003e\u003c\/div\u003e","brand":"Boston","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677214834990,"sku":null,"price":268.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_eee62d2d-7282-4dd7-bd0a-7b0648e28f95.jpg?v=1769559512","url":"https:\/\/plgautomation.com\/products\/boston-gear-f71820b5g-speed-reducer","provider":"PLG Automation ","version":"1.0","type":"link"}
