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\/p\u003e","brand":"2","offers":[{"title":"Default Title","offer_id":42823876083783,"sku":"PTK-10025","price":12.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/5569\/7735\/files\/ptk-10025.avif?v=1779824571","url":"https:\/\/slidelabsdrift.com\/products\/protek-rc-5x10x4mm-ceramic-metal-shielded-speed-bearing-2","provider":"SlideLabs","version":"1.0","type":"link"}
