The hottest new ceramic axis and bearing made in T

  • Detail

Taiwan, China has recently developed a micro motor made of ceramic shafts and bearings, which are 20 to 50 times more durable than traditional stainless steel products

according to the person in charge of DuPont performance materials of Taiwan Sanjiang technology company, which developed the product, the ceramic axis and bearing are made of zirconia with 7 or 8 formulas and sintering technology. First, zirconia is mixed with adhesive, and then high-precision injection molding is used to inject the cataclysmic machine produced in the past three years. After degreasing and sintering in a sintering furnace, the semi-finished products are ground, and then the self-developed lubricating oil film is added to make high-strength and wear-resistant ceramic shafts and bearings. In order to reduce the contact surface between the ceramic axis and the bearing and reduce the heating, the axis is not completely connected with the end face of the working piston, which is the working surface bearing that bears pressure oil. Instead, a fine groove is designed on the waist of the axis to make it stuck on the bearing and reduce the contact surface

compared with this product, the traditional 420 series stainless steel shaft and bearing can produce high heat after mutual friction during operation, which can deform the steel balls in the bearing for a long time, and the whole fan performance will be scrapped before it meets the requirements or the radiator

it is reported that this kind of ceramic shaft and bearing is mainly used in the radiator of computer shell and the micro cooling fan of central processing unit (CPU). Due to its low calorific value, its durability has been greatly improved. At present, it has been recognized by ASUS, Gigabyte and other computer motherboard manufacturers. Previously, Japan has also developed micro ceramic shafts and bearings, but the sintering is not ideal, resulting in low yield, coupled with high production costs, the application prospect is not very clear
