Ceramic bearings run smoother with less friction than regular bearings, and should last three to four times as long. We highly recommend the use of Tri-Flow Teflon based bicycle lubricant for ceramic bearings. Teflon lubricant works the best as the Teflon will impregnate the balls for longer life.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"float\"\u003e\n\u003cli\u003eAgama A215\u003c\/li\u003e\n\u003cli\u003eAgama A215 SV\u003c\/li\u003e\n\u003cli\u003eAgama A215E\u003c\/li\u003e\n\u003cli\u003eGMade R1\u003c\/li\u003e\n\u003cli\u003eHB Racing D216\u003c\/li\u003e\n\u003cli\u003eHB Racing D413\u003c\/li\u003e\n\u003cli\u003eHB Racing D8 Original\u003c\/li\u003e\n\u003cli\u003eHB Racing D812\u003c\/li\u003e\n\u003cli\u003eHB Racing D8T Original\u003c\/li\u003e\n\u003cli\u003eHoBao Hyper 10 SC\u003c\/li\u003e\n\u003cli\u003eKyosho MP10\u003c\/li\u003e\n\u003cli\u003eKyosho MP9\u003c\/li\u003e\n\u003cli\u003eKyosho MP9 TKI2\u003c\/li\u003e\n\u003cli\u003eKyosho MP9 TKI3\u003c\/li\u003e\n\u003cli\u003eKyosho MP9 TKI4\u003c\/li\u003e\n\u003cli\u003eKyosho MP9e\u003c\/li\u003e\n\u003cli\u003eKyosho MP9e Evo\u003c\/li\u003e\n\u003cli\u003eKyosho MP9e TKI4\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT 1.0\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT 2.0\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT 3.0\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT 4.0\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT Nitro RTR\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT-E 4.0\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT-T 1.0\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT-T 2.0\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT-T 3.0\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT-T 4.0\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT-T E 3.0\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT-T Nitro RTR\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT-T RTR\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT-X\u003c\/li\u003e\n\u003cli\u003eLosi 8IGHT-XE Race\u003c\/li\u003e\n\u003cli\u003eS-Workz S35-2E\u003c\/li\u003e\n\u003cli\u003eTekno RC EB410 Original\u003c\/li\u003e\n\u003cli\u003eTekno RC EB48.3\u003c\/li\u003e\n\u003cli\u003eTekno RC EB48SL\u003c\/li\u003e\n\u003cli\u003eTekno RC ET410 Original\u003c\/li\u003e\n\u003cli\u003eTekno RC ET48 Original\u003c\/li\u003e\n\u003cli\u003eTekno RC ET48.3\u003c\/li\u003e\n\u003cli\u003eTekno RC NB48.3\u003c\/li\u003e\n\u003cli\u003eTekno RC NT48.3\u003c\/li\u003e\n\u003cli\u003eTekno RC SCT410.3\u003c\/li\u003e\n\u003cli\u003eTraxxas TRX-4\u003c\/li\u003e\n\u003cli\u003eTraxxas TRX-4\u003c\/li\u003e\n\u003cli\u003eVaterra Twin Hammers\u003c\/li\u003e\n\u003cli\u003eVetta Karoo\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ProTek","offers":[{"title":"Default Title","offer_id":40029456138377,"sku":"PTK-10060","price":17.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0682\/8293\/products\/ptk-10060.jpg?v=1645736211","url":"https:\/\/www.perantinostravel.com\/products\/protek-rc-5x11x4mm-ceramic-metal-shielded-speed-bearing-2","provider":"perantinostravel","version":"1.0","type":"link"}
