{"product_id":"the-hub-ceramic-6802-2rs-ceramic-ball-hub-bearing","title":"The Hub Ceramic | 6802-2RS Ceramic Ball Hub Bearing, 15x24x5mm","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003eYour wheels turn more than any other part of the bicycle. Everything else on the bike moves occasionally; the hubs move constantly, thousands of revolutions per hour, in whatever weather the ride began in. It follows that the bearing inside the hub is the part where a small decision becomes a large one.\u003c\/p\u003e\n\u003cp\u003eThe 6802-2RS is a 15 x 24 x 5mm hub bearing with ceramic balls running in bearing steel races, sealed on both sides. Ceramic balls are lighter than steel balls of the same size, which reduces the centrifugal load they place on the race at speed, and they run cooler because there is less mass to move and less friction to generate heat. The steel races keep the cost of the assembly in the range where replacing a pair of hub bearings stays a normal service item rather than a project.\u003c\/p\u003e\n\u003cp\u003eThis is a single piece, and that is deliberate. Hubs differ: a front hub carries radial load, a rear hub carries radial load plus drive torque, and the two sides of a hub are not always the same bearing. Selling one at a time means you buy what the frame actually needs instead of a fixed lot that leaves you with pieces that fit nothing. ABEC-3 tolerance, 2RS seals, 15 x 24 x 5mm, RoHS compliant, ready for a standard hub service.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThe hub is where the whole ride is decided, five millimetres at a time.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003chr style=\"margin:24px 0;border:0;border-top:1px solid #eee;\"\u003e\u003cdiv class=\"product-features\"\u003e\n\u003ch3\u003eWhat The Specification Delivers\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;\"\u003e\n\u003cli style=\"padding:8px 0;\"\u003e✦ Ceramic balls in bearing steel races: lighter rotating mass, lower running temperature\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;\"\u003e✦ 2RS double sealing against water, grit, and road spray\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;\"\u003e✦ ABEC-3 tolerance suited to hub service rather than instrument duty\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;\"\u003e✦ Standard 6802 envelope at 15 x 24 x 5mm for wide hub compatibility\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;\"\u003e✦ Sold as a single piece, because front and rear hubs do not share bearing loads\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;\"\u003e✦ Bearing steel races that hold their geometry through repeated service\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;\"\u003e✦ RoHS compliant construction\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;\"\u003e✦ Drop-in replacement for hub and wheel service work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-specs\" style=\"margin-top:26px;\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;\"\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e 6802-2RS (SC6802-2RS)\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Ceramic ball bearing\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 15mm ID x 24mm OD x 5mm width\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eTolerance grade:\u003c\/strong\u003e ABEC-3\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eSeals:\u003c\/strong\u003e 2RS sealed both sides\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eRing material:\u003c\/strong\u003e Bearing steel\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eBall material:\u003c\/strong\u003e Ceramic\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 piece per lot\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e RoHS\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Bicycle hub, front and rear\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-applications\" style=\"margin-top:26px;\"\u003e\n\u003ch3\u003eWhere It Belongs\u003c\/h3\u003e\n\u003cp\u003eWheel builders use the 6802 as a service part when a client's hub develops play or roughness that cannot be adjusted out.
