Silicone seals enable “butter-smooth” rotational movements with unique protection against dust, water and dirt. Equipped with aluminum bearing shells and high-quality and durable industrial bearings. The rotor bearing technology ensures silky smooth running for a long time. Despite a total weight of only 110g, the bearings have maximum rigidity and optimal power transmission.\u003cbr\u003e\n\u003cbr\u003e \nThe UBB 4630 for the BB 386 EVO bearing standard, in steel, the newest member of the UBB family (Universal Bottom Bracket), uses a threaded sleeve to connect both bearing shells together. This connection reduces stresses that usually act on the Press Fit sleeves. Dimensional tolerances of the bottom bracket housings can be compensated for, which leads to better parallelism of the bearings and thus to better smooth running of the crank movement and lower noise. The external bearing shells additionally increase rigidity. The better fit of the bearing\/sleeve unit protects the bearings from bearing overload and improves the longevity of the bearings. The inner sleeve also protects against cable damage or damage to the electronics, as there is no friction with rotating parts.\u003cbr\u003e\n\u003cbr\u003e\n The Rotor UBB 386 EVO PressFit 4630 Road bottom bracket requires a bottom bracket shell with an inner diameter of 46mm and a shell width of 86.5mm.\u003cbr\u003e\n\n\u003cul\u003e \n\u003cli\u003eMaterial: aluminum bearing shells\u003c\/li\u003e\n\n\u003cli\u003e Manufacturer number: C04-029-01010\u003c\/li\u003e\n\n\u003cli\u003e Special precision industrial bearings for a long, silky-smooth run\u003c\/li\u003e\n\n\u003cli\u003e Lightweight and durable\u003c\/li\u003e\n\n\u003cli\u003e Steel bearings\u003c\/li\u003e\n\n\u003cli\u003e Weight: 110g\u003c\/li\u003e\n\n\u003cli\u003e Color: Black\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n","brand":"ROTOR Bike","offers":[{"title":"Default Title","offer_id":47310844658004,"sku":"56186","price":99.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/9148\/0660\/products\/Rotor-UBB386Evo-4630_9c097400-65d0-465e-b419-a49a2e1fd7a8.jpg?v=1701988046","url":"https:\/\/smpirts.com\/en\/products\/rotor-ubb-bb386evo-pressfit-4630-road-innenlager-stahl-30mm","provider":"SMParts","version":"1.0","type":"link"}
