Specifically, the model UCN-80B-25X25 uses 25 mm bores on both sides (25×25) and measures 80 mm in overall length, enabling a compact yet rigid connection in precision drives. It secures shafts with a bolt-clamp mechanism to maintain concentricity under load, a hallmark of Sakai's precision couplings. For the 25-25 variant, the assembly provides an allowable torque of 80 N·m and an allowable misalignment (eccentricity) around 0.2 mm, reflecting its suitability for moderate-to-high torque transmission while forgiving minor shaft runout. Part of Sakai's UCn-B lineup, this series emphasizes repeatable alignment and robust torque transfer in precision machinery, making it appropriate for applications where shaft alignment matters and drift cannot be tolerated.\u003c\/p\u003e\u003c\/div\u003e","brand":"Sakai","offers":[{"title":"New","offer_id":46284089950442,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-022.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/sakai-ucn-80b-25x25-precision-shaft-couplings","provider":"GTG Hardware","version":"1.0","type":"link"}
