Machine Tool Spindle Ball Bearings - Alpine Bearing

Ball Bearing Description. 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%.
