Our Ceramic ball bearings 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 for aluminum, hard wood, then ceramic ball bearings better than steel ball bearings. working environment temperature is usually -10 ~ 40 .Before installing the first
