In ATRA-FLEX systems, the flex hub is installed on the shaft with the drive ring fitted over the hub, forming a modular torque-transmission assembly that accommodates misalignment and torsional variation. The T-Series comprises four parts—the ring hub, flex hub, insert, and drive ring—allowing a complete, customizable coupling solution for belt-drive applications. The T4 size corresponds to a 3.375-inch footprint (MBFH in Tsubaki catalogs), making it suitable for compact installations where space is at a premium. As with other ATRA-FLEX components, this flex hub is designed to deliver reliable performance from a trusted manufacturer of flexible couplings, enabling smooth operation in belt-driven machinery that requires controlled misalignment tolerance.\u003c\/p\u003e\u003c\/div\u003e","brand":"Atra","offers":[{"title":"New","offer_id":51660343410990,"sku":null,"price":289.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8781b254-3cd9-4635-9550-569b4b4948c5.jpg?v=1769536496","url":"https:\/\/plgautomation.com\/products\/tsubaki-t4-fh-3-375-flex-hub-atra-flex-belt-drive-hub","provider":"PLG Automation ","version":"1.0","type":"link"}
