The difference between ceramic bearings bearing steel bearings
Release date:2023-06-14

image.png一、 The difference between all ceramic bearings and bearing steel bearings


1. The fatigue life of all ceramic bearings can be about 10 to 50 times longer than that of all steel bearings.


Hybrid ceramic bearings have a lifespan that is about 3-5 times longer than that of all steel bearings


In terms of service life, ceramic bearings are much longer than bearing steel bearings.


2. The friction coefficient of ceramic bearings is low, so the lubrication capacity of oil lubricated ceramic bearings is still no less than that of traditional lubricants commonly used in steel bearings when the lubricating oil becomes thin or lacking. The friction coefficient of ceramic bearings is less than 30% of the bearing stiffness coefficient.


3. The expansion coefficient of ceramic bearings is less than 20% of the bearing stiffness coefficient (ceramic bearings have good heat resistance).


4. Ceramic bearings have a compressive strength of 5-7 times that of bearings.


5. The density of ceramic bearing balls is less than 40% of the bearing stiffness.


6. The centrifugal reduction of the outer ring of the ceramic bearing rotation is 40%.


7. Ceramic bearings have tensile and bending resistance=bearing stiffness.
