This hub is the male element that accepts a matching elastomer flex insert and a drive ring to complete a three-piece jaw coupling, enabling torque transmission between misaligned shafts. When paired with corresponding ATRA-FLEX A-Series components, the assembly provides a compact, robust connection that accommodates angular and parallel misalignment while helping damp vibration and shock loads common in industrial drives. The A1 size denotes the specific bore and footprint within the A-Series, allowing designers to select the correct hub to match their motor or gearbox shaft diameter. Typical applications for ATRA-FLEX jaw couplings include conveyors, pumps, fans, machine tools, and packaging equipment where reliable, removable couplings are preferred. This 28 mm bore hub is intended to mate with the compatible A-Series flex insert and drive ring to form a complete coupling assembly suitable for moderate torque transmission in general-purpose drives.\u003c\/p\u003e\u003c\/div\u003e","brand":"ATRA-FLEX","offers":[{"title":"New","offer_id":51660344918318,"sku":null,"price":33.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_225bf97c-eeb9-48ae-a6fa-3b68cad4c589.jpg?v=1769536510","url":"https:\/\/plgautomation.com\/products\/industrial-atra-flex-a1-28mm-coupling-hub-28mm","provider":"PLG Automation ","version":"1.0","type":"link"}
