Product Description
Thin Section 6844 220x270x24mm Deep Groove Zirconia Ball Bearings PTFE Cages ZrO2 Ceramic Bearing
Full Ceramic Bearing
Ceramic bearings have excellent performance with their special electrical and magnetism resistance, wear and corrosion resistance, maintenance free lubrication, high and low temperature resistance etc. So they are suitable to be used in tough environments and special conditions.
Our full ceramic ball bearings can be supplied with rings and balls made from zirconia (ZrO2) or silicon nitride (Si3N4). They are available as full complement (no cage) or with a cage made from PEEK or PTFE. Full ceramic bearings are for medium load and medium speed applications. It is not possible to achieve the inner and outer ring roundness that is found with precision steel bearings so full ceramic bearings have lower speed ratings.
ZrO2 Ceramic Ball Bearings
Zirconia ceramic bearings utilize ZrO2 (Zirconia) as the main material for the bearings, featuring excellent hardness, high strength, and wear resistance. They also exhibit high corrosion resistance in most acidic and alkaline environments. Zirconia ceramic bearings are commonly used in high-temperature environments, such as turbochargers, dental tools, and cutting equipment.
Material Types:
1.Silicon Nitride (Si₃N₄): The gold standard for ceramic elements. It offers higher fracture toughness, extreme hardness, and superior fatigue resistance.
2.Zirconia (ZrO₂): Often tougher and more resilient to shock loads, with thermal expansion properties more closely resembling steel.
3.Silicon Carbide (SiC): Used for incredibly high-temperature and highly corrosive industrial applications.
Characters:
EXTREME HIGH TEMPERATURE CAPABILITY
When temperatures exceed 572 Deg. F. (300 Deg. C) standard 440C stainless steel and 52100 chrome steel materials begin to lose their mechanical properties. Full ceramic bearings have the advantage of extreme high temperature capability up to 1800 Deg. F.
LIGHT WEIGHT
Full ceramic bearings are light weight. In applications implementing many bearing units or utilizing larger sizes this can help reduce the total weight of the overall product. Reducing weight can reduce effects such as vibration and stress caused by out of balance applications. Weight reduction in rotating assemblies can increase speed capability and efficiency.
NON-MAGNETIC
Full ceramic bearings are non-magnetic and will not cause interference in applications where there is strong magnetic field exposure such as electron beam processes.
EXTREME CORROSION RESISTANCE
Full ceramic bearings are highly corrosion resistant and will stand up to most common acids, they will not corrode in exposure to water or salt water.
ISOLATING & NON-CONDUCTIVE
Full ceramic bearings are electrically non-conductive and thermal insulating.
