440C low temperature ceramic ball bearing S7305 7307

stainless steel series bearings are made from 440C or Cronidur 30, using high-quality ceramic balls. These series bearings can be used in super low/high temperatures, -180 to 400 degrees. The precise manufacturing process and special heat treatment ensure the rust resistance and long service of the bearings. The performance of 440C or X30 bearings is 3-4 times of normal chrome steel bearings. Bearings can be offered in standard sizes or customized sizes.
