Featuring 52100 High-Carbon Chromium alloy races and grade 5 balls with 90% fill, this radial bearing is lubricated with high-pressure, water-proof grease to ensure smooth performance under various conditions. The innovative LLU\/LLB seal design offers superior protection by positioning the more robust LLU seal outward to block water and dirt, while the lighter-contact LLB seal faces inward to retain grease efficiently.\u003c\/p\u003e\n\n\u003cp\u003eBuilt to withstand the rigors of cycling, these bearings incorporate deep groove races that accommodate large balls for enhanced load capacity and longevity. Enduro’s commitment to quality is evident in their use of premium materials and dual-lip seals riding in a micro groove, creating a labyrinth that maximizes defense against contamination. Suitable for hubs and bottom brackets, the MR15307 promises reliable operation and extended service life.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eProviding smooth and consistent rotation in bicycle hubs and bottom brackets\u003c\/li\u003e\n  \u003cli\u003eResisting water and dirt contamination thanks to advanced LLU\/LLB seal design\u003c\/li\u003e\n  \u003cli\u003eEnhancing durability with high-quality 52100 High-Carbon Chromium steel and grade 5 balls\u003c\/li\u003e\n  \u003cli\u003eMaintaining lubrication with Kyodo Yushi PS-2 high-pressure grease for long-lasting performance\u003c\/li\u003e\n  \u003cli\u003eSupporting high loads through deep groove races designed for larger balls\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 outside of cycling components where different bearing specifications are required\u003c\/li\u003e\n  \u003cli\u003eEnvironments with extreme temperatures beyond standard bicycle use conditions\u003c\/li\u003e\n  \u003cli\u003eHeavy industrial machinery that demands specialized heavy-duty bearings\u003c\/li\u003e\n  \u003cli\u003eUse in systems requiring non-standard bearing dimensions beyond 15mm x 30mm x 7mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does ABEC-5 rating mean for this bearing?\u003c\/strong\u003e\u003cbr\u003eThe ABEC-5 rating indicates a high level of precision and tolerance, ensuring smooth operation and reduced friction, ideal for bicycle components needing consistent performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these bearings compatible with all types of bicycles?\u003c\/strong\u003e\u003cbr\u003eThey are primarily designed for use in hubs and bottom brackets of most standard bicycles but it’s important to verify dimensions and requirements for specific models.\u003c\/p\u003e","brand":"Enduro Bearings","offers":[{"title":"Default Title","offer_id":45499388395695,"sku":"EB9809","price":9.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/43949-pm.jpg?v=1768509641","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/enduro-bearings-mr15307-abec-5-radial-bearing-for-bicycle-hubs-bottom-brackets","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
