II. Features and benefits of hybrid ceramic bearings
Features
|
Benefits
|
Higher hardness of rolling element
|
- Better wearability - Greater durability - Longer service life
|
Lower gravity
|
- Lightweighting the system� - Lower centrifugal force during rotation, consequently less bearing wear and heat generation and bearings can run at higher speed
|
Higher stiffness
|
- Increase the rigidity of system� - Less sphere deformation under load and this will transfer energy better
|
Higher precision and better surface finish of ceramic balls
|
- Less friction between ceramic balls and races - Less wear
|
Good corrosion resistance
|
- Less maintenance or maintenance free - Races will not block due to rusty
|
Self-lubrication
|
- Suitable for dry run
|
Magnetism free
|
- Less magnetic contaminations to be magnetized into the raceway that can affect smooth rotation and destroy the raceway
