Martensitic stainless steel 440 is widely used in non-standard design. The heat-treated 440 stainless steel material can also provide high precision and wear resistance comparable to high carbon chromium steel while it is clean and corrosion resistant. It is one of the ideal materials for bearing rings. Matched with ceramic balls which with low density, high hardness, low friction coefficient, non-magnetic and electrical insulation, wear resistance, good self-lubrication and good rigidity, combined into a stainless steel hybrid ceramic ball bearing. The ceramic balls can be made of ZrO2 balls, SI3N4 balls and SiC ceramic balls.

Advantage Of 440 Stainless Steel Hybrid Ceramic Ball Bearing
1. High temperature resistance: Due to the small thermal expansion coefficient of the ceramic ball, the bearing will not be stuck due to the expansion of the bearing ball in a high temperature environment, which greatly increases the temperature range of the bearing.
2. High speed: The ceramic ball has the characteristics of oil-free self-lubrication and low friction coefficient. And because of the low density, the centrifugal force is also small. So the speed of the bearing can be very high. The speed can reach more than 1.5 times that of normal bearings.
3. Long life: The ceramic ball can work in a grease-free condition. Even if the bearing grease is dry, the bearing can still operate normally. This avoids the premature damage of normal bearings due to the drying of grease. According to our tests and customer feedback, hybrid ceramic ball bearings are 2 to 3 times the life of normal bearings.
4. Insulation: The use of ceramic balls can insulate the inner and outer rings of the bearing.
