Crafted with 52100 High-Carbon Chromium alloy races and grade 5 balls, this bearing ensures long-lasting reliability and smooth operation. The 90% fill, high-pressure, water-proof grease maintains optimal lubrication, extending the bearing’s lifespan even in demanding conditions.\u003c\/p\u003e\n\n\u003cp\u003eSpecifically designed for cycling applications, the unique LLU\/LLB seal configuration offers outstanding protection. The robust LLU seal faces outward to shield against water and dirt contamination, while the lighter-contact LLB seal inward minimizes drag and keeps grease securely inside. This smart seal design balances protection and efficiency, enhancing your ride quality.\u003c\/p\u003e\n\n\u003cp\u003eEnduro’s commitment to quality is evident in their use of deep groove races that accommodate larger balls, reducing friction and increasing durability. Whether you choose High-Carbon Chromium Steel, 440C Stainless Steel, Ceramic-Hybrid, or XD-15 variants, these bearings provide reliable performance with superior sealing technology and premium Kyodo Yushi PS-2 grease.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eProviding smooth, low-friction rotation for bottom brackets and other bicycle components\u003c\/li\u003e\n  \u003cli\u003eWithstanding harsh environmental conditions thanks to advanced LLU\/LLB dual-lip seals\u003c\/li\u003e\n  \u003cli\u003eMaintaining lubrication and extending bearing life with high-quality water-proof grease\u003c\/li\u003e\n  \u003cli\u003eEnhancing durability and precision with ABEC 5 grade and superior materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eApplications requiring bearings larger than the 10mm x 22mm x 6mm size\u003c\/li\u003e\n  \u003cli\u003eSituations where non-standard seal types are preferred over LLU\/LLB configurations\u003c\/li\u003e\n  \u003cli\u003eUse in non-bicycle machinery where different bearing specifications are critical\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does ABEC 5 mean for this bearing?\u003c\/strong\u003e\u003cbr\u003eABEC 5 indicates a high level of precision and tolerance in the bearing’s manufacture, ensuring smooth and efficient rotation ideal for cycling components.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do the LLU\/LLB seals improve bearing performance?\u003c\/strong\u003e\u003cbr\u003eThe LLU seal faces outward to protect against contamination, while the LLB seal faces inward to reduce drag and keep grease inside, combining protection with efficiency.\u003c\/p\u003e","brand":"Enduro Bearings","offers":[{"title":"Default Title","offer_id":45499388428463,"sku":"EB9743","price":7.53,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/43947-pm.jpg?v=1768525742","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/enduro-bearings-61900-llu-llb-abec-5-bicycle-bearing-with-dual-lip-seals","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
