Our Ceramic ball bearings spindle use 4 pcs ceramic ball bearings. 2. Ceramic ball bearings areresistant to high temperatures and low heat, usually 3-5 degrees lower than steel ball bearings during using .3. Ceramic ball bearings have low friction, low noise and long service life. 4. If you want to use the spindle for aluminum, hard wood, then ceramic ball bearings better than steel ball bearings.
