I. Components of a hybrid bearing
1) Steel races
2) Ceramic balls Si3N4
3) Ball Cage/RetainerStee
4) No Seals/Shields
5) Lubricant Dry |
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 systemÃ�Â
- 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 systemÃ�Â
- 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
