It features a 1-3\/4 in (1.75 in) blank bore, representing the minimum bore before re-boring to the exact shaft diameter specified by your installation. In Atra-Flex terminology, RSB stands for Rough Stock Bore (MINIMUM RE-BORE), meaning the bore must be enlarged in the field to reach the final specification, while the T7 designation identifies the hub geometry within the T-Series lineup. This hub provides a robust interface for mounting a driven component to a shaft in industrial drives, enabling precise, customized bore sizing without sourcing a pre-bored unit and supporting reliable alignment when paired with compatible shaft hardware and fasteners. As a member of the Atra-Flex T-Series, it is designed to integrate with a range of standard components used in mechanical power transmission systems, offering a flexible, field-adjustable solution for applications where exact bore size is determined during installation.\u003c\/p\u003e\u003c\/div\u003e","brand":"Atra-Flex","offers":[{"title":"New","offer_id":51660343738670,"sku":null,"price":943.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_4009f610-24ba-454b-9c61-4c3694b1d48a.jpg?v=1769536501","url":"https:\/\/plgautomation.com\/products\/industrial-atra-flex-t7fh-rsb-1-3-4-blank-bore-flex-hub","provider":"PLG Automation ","version":"1.0","type":"link"}
