low temperature bearings resistant bearings that can withstand temperatures from minus 40 degrees Celsius to minus 120 degrees. They are often used in aerospace, deep sea exploration, and liquid nitrogen equipment. Our deep groove ball bearings through the authority of the department has been able to test all the above requirements. Low temperature bearings are divided into bearing steel, stainless steel, ceramics and other materials, the current bearing steel and stainless steel bearings can reach minus 60 degrees Celsius. Our ultra-low temperature ceramic bearings can reach minus 90 degrees Celsius to minus 120 degrees Celsius. Low-temperature bearings and ordinary bearings are not the same, ordinary bearings can withstand the minimum temperature of minus 40 degrees Celsius, if you need to achieve lower temperatures, ordinary bearings can not be achieved. At such a low temperature of ordinary bearings in the internal will produce crystallization affect the rotation, while the bearing is directly frozen and locked.
