What are the advantages of ceramic bearings over similar products?

The outer raceway of the ceramic bearing is spherical and self-aligning, which can compensate for errors caused by misalignment and shaft deflection. It is used to produce the misalignment between the shaft and the casing or the shaft deflection part and the alignment part required for high temperature, low cold, corrosion, magnetic field non-insulation, etc.

(1) Anti-magnetic bearings: ceramic bearings do not absorb dust because they are non-magnetic, which can reduce the peeling of the bearing surface, thereby reducing the running noise. It can be used in the fields of demagnetization equipment and precision instruments.

(2) Electrically insulated bearings: ceramic bearings can avoid arc damage to the bearings due to their high resistivity, and can be used in various electrical equipment requiring insulation.

(3) Vacuum bearings: Due to the unique oil-free self-lubricating properties of ceramic materials, in the ultra-high vacuum environment, the problem that ordinary bearings cannot be lubricated can be overcome.

1. The fatigue service life of all-ceramic bearings is 10-50 times longer than that of all-steel bearings. The service life of hybrid ceramic bearings will be about 3-5 times longer than that of all-steel bearings; in terms of service life, ceramic bearings are far higher than metal bearings.

2. The friction coefficient of ceramic bearings is low, so oil-lubricated ceramic bearings have higher lubricating ability than traditional greases often used in steel bearings in the case of thinning or lack of lubricating oil.

3. The performance of ceramic bearing steel is larger than that of metal bearing, the elastic modulus of ceramic material is high, and its rigidity is 15-20% larger than that of ordinary steel bearing.

4. Compared with metal bearings, ceramic bearings are more resistant to corrosion and wear. Due to the difference in its own original material, it can directly cause the corrosion resistance and wear resistance of ceramic bearings to be better than metal bearings.

What are the material characteristics of ceramic bearings?

Mechanical properties of ceramic materials

Ceramic materials are engineering materials with the best stiffness and high hardness standards, most of which are above 1500HV. Ceramics have high compressive strength, but low tensile strength and poor plasticity and toughness.

Thermal characteristics of ceramic materials

Ceramic materials usually have a high melting point (mostly above 2000 ° C), and have excellent chemical stability at high temperatures; the thermal conductivity of ceramics is lower than that of metal materials, and ceramics are also good thermal insulation materials. At the same time, the linear expansion coefficient of ceramics is lower than that of metals. When the ambient temperature changes, ceramics have good dimensional stability.
