{"product_id":"losi-los3467-15x21x4-shielded-ball-bearing","title":"Losi LOS3467 15x21x4 Shielded Ball Bearing","description":"\u003cp\u003eThis shielded ball bearing is sized 15 x 21 x 4mm and functions as a universal hardware replacement for any Losi vehicle using this bearing size in its drivetrain or suspension. A rubber seal keeps dust, dirt, and debris from working into the races, while a factory grease fill keeps the balls turning smoothly and helps the bearing resist wear over long-term use. Because bearings support rotating components like wheels, gear shafts, and differential outputs, a worn or contaminated bearing can introduce drag, noise, and premature wear on the parts around it, so replacing one before it fails helps protect the rest of the drivetrain. This is a direct factory replacement, matching the original equipment dimensions so it presses into the same bearing pockets without any modification to the chassis or hub. The package includes two bearings, enough to refresh a matched pair on an axle or shaft during routine maintenance. Keeping fresh, properly sealed bearings on hand is a straightforward way to maintain smooth rolling performance and cut down on drivetrain wear over time.\u003c\/p\u003e","brand":"PowerHobby","offers":[{"title":"Default Title","offer_id":67651195600984,"sku":"LOS3467","price":11.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0567\/0554\/8376\/files\/LOS-3467_A0_A2IT05K1.jpg?v=1791387540","url":"https:\/\/beavertonmilestonehobby.com\/products\/losi-los3467-15x21x4-shielded-ball-bearing","provider":"Beaverton Milestone Hobby","version":"1.0","type":"link"}
