BALL BEARING
INDUSTRY
MATERIALS
APPLICATION
When a metal ball bearing reaches its technical limit, ceramic materials can often push these limits.
Ball bearings are available in either full ceramic or hybrid form. The emphasis is on application at higher temperatures and under corrosive conditions. Lubrication is usually less critical. At low loads and speeds, there is no need for lubrication at all.
The emphasis is on application at higher temperatures and under corrosive conditions.
If necessary, we can also develop and produce extremely accurate ceramic bearings at Ceratec.
We can also integrate ball bearings into ceramic components by integrating raceways into the components themselves. This is more accurate and cost-effective than assembling multiple components.
PROPERTIES
- -170 ˚C to +650 ˚C
- Lubricated by the medium, or semi-dry
- Applicable in MRI or Röntgen equipment
- Highly corrosion resistant
- Metal/ceramics system
- Electrically insulating
- Easy to install
- Low weight
- Non-magnetic
- Vacuum, ultra-high vacuum
- Very low friction
PRODUCTS
If there are circumstances in which metal or plastic bearings are no longer an option, then we can offer added value with ceramic bearings.
Examples of environments where ceramic ball bearings have been used successfully:
SEAWATERCeramic product: Ceramic ball bearing / linear guide, ceramic raceways and balls, lubricated by seawater, possibilities for buoys, underwater robots.Advantage: The service life of a mildly loaded bearing will be very long - up to infinity.
MEDICAL APPLICATIONCeramic product: Ceramic roller bearing, ceramic raceways, ceramic balls.Advantages: Non-magnetic properties in MRI or special reflection in CT scanners can be beneficial.
ULTRA-HIGH VACUUMCeramic product: Roller bearings made entirely of ceramics.Advantage: No lubrication required in ultra-high vacuum.
MAGNETICALLY SENSITIVE ENVIRONMENTCeramic product: Ceramic roller bearings.Advantage: Because in some applications the magnetic fields are so strong that no magnetic or conductive material may/can be used, we can still use full ceramic ball bearings.
HIGH ACCELERATIONSCeramic product: Lightweight ball bearings.Advantage: Roller bearings made of ceramics can be 60% lighter in weight than metal bearings of the same dimensions. This can be advantageous in fast running applications and in case of high accelerations or decelerations.
LOW FRICTIONCeramic product: Ceramic roller bearings.Advantage: Because ceramic materials are harder and stiffer, they theoretically have a lower rolling resistance than metal bearings, as less elastic deformation occurs.
ADDED VALUE
- Ceramics are lighter, harder, more wear and corrosion resistant and can withstand higher temperatures than metals and plastics.
- Longer service life
- Very low friction
- Together with you, we assess for each application what offers the most added value for you.
DIMENSIONS
Ceramic ball bearings are developed according to customer specifications. Often the dimensions from the industry are common.
- From shaft size ∅7 mm
- Also available as a hybrid bearing: metal bearing shells with ceramic balls
- If necessary, we can also develop and produce extremely accurate ceramic bearings at Ceratec.
- We can also integrate ball bearings into ceramic components by integrating raceways into the components themselves. This is more accurate and cost-effective than assembling multiple components.
SPECIFICATION
- Materials: silicon nitride, zirconium oxide, specials in consultation
- Cage: several possibilities
- Including metal at high temperatures
