Alpine Bearing, Inc. Sealed 100 Ceramic Ball Bearings CXMC-2115SS

Ceramic balls are 50% lighter than steel balls, and because they are almost perfectly smooth, they exhibit vibration levels 2-7 times lower than conventional steel ball bearings. These bearings also run at significantly lower operating temperatures, and allow running speeds to increase by as much as 25%. Ceramic ball bearings have been proven to last up to 5 times longer than conventional steel ball bearings and lower operating temperatures help extend lubricant life. Ball Bearing Features 15° & 25° contact angles add “DL” for light preload add “DM” for medium preload add “DH” for heavy preload greased for life singles, pairs, tri-sets & quad-sets
