Description

Ceramic Lightning, shielded bearings are specially designed for relatively clean operating environments. These bearings have ceramic balls, with stainless steel races, retainers and shields. Ceramic hybrids are lighter, capable of achieving higher RPMÆs and sustaining higher operating temperatures than traditional bearings. Bearings that are packed in grease will require a short break in period to loosen up. Grease can be removed before shipping upon request. Grade 10 SI3N4 Ceramic Balls, ABEC #5, (8x16x5)MM

    I stumbled across Boca Bearings by accident. A fortunate accident indeed. Great products! I have restored a 30+ year old Penn reel to better than new condition. Now I am looking forward to upgrading some other reels. Great site and quick shipping. Thanks!

    Silicon Nitride Ball  
    I almost thought I got a bearing with steel balls but on more research I realized it was Silicon Nitride Ball. In my mind I pictured a ceramic ball as looking more like a stone. I had no idea that Silicon Nitride shined like crystal ball and reflected almost like a steel ball. It's the real McCoy!
