This carbon-steel hub is machined to tight tolerances for balanced operation and features a 1.625 in (1-5\/8 in) bore compatible with standard M1 inserts in the Millennium family. As part of the US Tsubaki Atra-Flex lineup, the M1 hub serves as the hub half of a non-spacer jaw coupling, enabling easy assembly with the corresponding inserts to transfer torque while accommodating minor shaft misalignment and damping vibration. In Millennium M-Series design, coupling inserts can be swapped to adjust bore size or torque characteristics, enabling quick adaptation without replacing the entire coupling. Typical applications include motor-to-drive connections in industrial equipment such as conveyors, pumps, fans, and other machinery where reliable torque transfer and straightforward maintenance are valued.\u003c\/p\u003e\u003c\/div\u003e","brand":"Atra","offers":[{"title":"New","offer_id":51660343509294,"sku":null,"price":43.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_36aa8572-5deb-4b79-9700-395dbb71b6da.jpg?v=1769536498","url":"https:\/\/plgautomation.com\/products\/industrial-m1hhub-shaft-coupling-millennium-m1-hub","provider":"PLG Automation ","version":"1.0","type":"link"}
