Measuring 17mm x 30mm x 7mm, it is primarily designed for use as a hub bearing but can also serve as a pivot bearing. Its ABEC-5 rating ensures precision and smooth rotation, making it ideal for demanding applications. Featuring a deep-groove design and Grade 10 balls, this bearing guarantees durability and efficiency under stress.\u003c\/p\u003e\n\n\u003cp\u003eEquipped with dual-lip seals, the LLU seal on the outside protects against dirt and moisture, while the lighter-contact LLB seal inside retains high-pressure, waterproof grease with a 90% fill. The C3 clearance specification is optimized for tighter press-fit bearing bores, providing a precise and secure fit. Enduro Bearings are known for their advanced engineering, including deepest groove races and a micro-groove labyrinth seal that offers superior protection against contamination and wear.\u003c\/p\u003e\n\n\u003cp\u003eConstructed from high-carbon chromium steel, this bearing balances strength and corrosion resistance, ensuring longevity even under harsh conditions. With a static load capacity of 308lbf \/ 1.37kN and a lightweight design of just 15.86g, it enhances both performance and reliability for your wheels and hubs.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eReliable hub bearing performance with smooth rotation\u003c\/li\u003e\n  \u003cli\u003eDurable protection against dirt, water, and debris\u003c\/li\u003e\n  \u003cli\u003eOptimized fit for tighter press-fit bearing bores\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty applications requiring high static load capacity\u003c\/li\u003e\n  \u003cli\u003eLong-lasting use in wheels, hubs, and pivot points\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSuspension use where MAX-type bearings are preferred\u003c\/li\u003e\n  \u003cli\u003eApplications requiring non-standard bearing sizes\u003c\/li\u003e\n  \u003cli\u003eSituations demanding fully sealed or maintenance-free bearings beyond waterproof grease\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCan this bearing be used in suspension systems?\u003c\/strong\u003e\u003cbr\u003eWhile it can function as a pivot bearing, the MAX-type Enduro bearings are better suited for suspension applications due to their specialized design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the C3 clearance mean?\u003c\/strong\u003e\u003cbr\u003eC3 clearance indicates a slightly greater internal clearance, making this bearing ideal for tighter press-fit bores, ensuring smoother operation under load and thermal expansion.\u003c\/p\u003e","brand":"Enduro Bearings","offers":[{"title":"Default Title","offer_id":45499390263471,"sku":"EB9847","price":11.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/1708355647-27173500.jpg?v=1768525757","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/enduro-bearings-61903-llu-llb-c3-abec-5-silver-radial-hub-bearing","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
