Description of 6900 ZrO2 full ceramic bearing

ceramic bicycle rear bearings:

 

Full ceramic bearing introduction:

 

     Full Ceramic Bearings have the characteristics of anti-magnetic insulation, abrasion resistant,

oil-free self-lubricating and enduring extreme high or low temperature, so they can be used for

harsh environment and even under some special condition. The material of rings and rollers is jar

gonia(ZrO2) and the holder uses poly back fluoride(PTFE) as standard configuration. Generally,

we can use the reinforced nylon made of glass fiber 66(GRPA66-25), special engineering plastics

(PEEK, PI), nonrust steel(AISI SUS316 SUS304), brass(Cu) and so on. Ceramic deep groove ball

bearings are made entirely of ceramic material and are superior to common Steel Angular Contact

Bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher

RPM's, reduce overall weight or for extremely harsh environments where high temperatures and

corrosive substances are present.

 

Full ceramic beating ZrO2 material

 

Full ceramic beating ZrO2 material has perfect propriety such like suitable for low and high temperatures,

high load capacity,corrosion resistance, nonmagnetic insulated and self lubrication, Thus it suit for the

specific applications which are not acailable for bearing steel and hybrid construction ceramic ball

bearing materials.

 

Full ceramic bearing Si3N4 material

 

Full ceramic bearing Si3N4 material has similar propriety as ZrO2 material, besides it has low weight,

good wear resistance, high hardness, and it can bear higher temperature than ZrO2 material.

 

Full ceramic bearing SiC material

 

Compare with other 3 types of ceramic materials, full ceramic bearing SiC material is more outstanding

in these aspects: higher chemical corrosion resistance, better strength, higher hardness, higher wear

resistance, lower frictional properties, and suitable for the highest temperature.

 

Full ceramic bearing Al2O3 material

 

Full ceramic bearing Al2O3 material which uses 99% Al2O3 ceramic, its rolling parts are also using

Al2O3 ceramic as well.

 

Full ceramic plain bearing

 

Main material for full ceramic plain bearing are ZrO2, Si3N4 and SiC ceramic, diversified dimension can

be produced according to the customer require.

 

Full ceramic bearing of full complement balls

 

Full ceramic bearing of full complement balls has an add-ball gap on its side. Because using no retainer

design, the bearing is able to install more ceramic balls than the standard construction, so the heavier

load ability increased more. In addition, to avoid the limited of the retainer' s material, this bearing is

same as the full ceramic bearing of ceramic cage has corrosion resistance and high temperature

application. This series of bearing is not for high.

 

Full ceramic bearing with ceramic retainer

 

For meeting the more demanding requirement of high corrosion, higher of lower temerature, ceramic

retainer has better performance on wear resistance, corrosion resistance and self lubrication than

retainers with other materials, ceramic , its rolling parts are also usING aL2O3 ceramic as well.

 

Hybrid construction ceramic Ball Bearing

 

Hybrid construction ceramic ball bearing, inner ring and outer ring are made by metal, GCr15 or

AISI440Cmakes inner ring and outer ring. Ceramic ball have the following performance as low density,

high strength, low friction, wear resistance, self-lubrication and higher rigidity, it's the best choice for

rollers of the hybrid construction ceramic which are used in high-speed, high- precision and long life

applications.

 

PTFE has long-term application temperature -200°C to +260°C, has very strongly bears chemistry

corosiveness, to chemicals all anti-corrosive, the friction and coefficient is low, has the good electric

insulation, certainly not temperature influence.

 

Advantage:

 

1. High size stability

2. Continuous working temperature-70°C ~ 26°C

3. Surface friction coefficient 0.05-0.1

4. Anti-aging, don't burning

5. Bears each kind of strong acid Alkali Salt

6. Mechanical is good

7. Insulating prorerty

8. Anti-burns the nature

 

Applications:

1)  Power Tools

2)  Fans

3)  Washing Machines

4)  Pumps

5)  Electric Motors

6)  Sport Apparaus

7)  Textile Machined

8)  Skateboard Skate

 

Disadvantage:

 

1. The fluidity is bad

2. Difficult to fuse the processing

3. Cannot weld

Deep Groove Ball Bearing mainly take radial load as well as take moderate axial load.

With less coefficient of friction, high limiting speed, large size range and varations of structure, they

are suitable for precision instruments, low noise motors, automobiles,motorcycles,and other

common machinery, as a widely used type of bearings in machinery industry.

 

Sealed Deep Groove Ball Bearings
Deep groove Ball Bearings with sealing disks (contacting gaskets) or covering disks (non-contacting

gaskets) allow simple designs. Bearings are offered both with one and two sealing or covering

disks. Bearings with two-side gaskets are filled with top quality grease. Sealed bearings can be

used in a temperature range from – 30 °C to max. 110 °C (short term) for contacting and up to

max. 120 °C for non-contacting gaskets. One should note here, that the period of grease use will

reduce at a permanent temperature of > 70 °C. Special greases are offered for such cases.

Deep groove ball bearings with annular groove in outer ring
Deep groove ball bearings with annular groove in the outer ring simplify the design in many

cases because they can be fixed simply by a snap ring and axially in the housing to save space.

These bearings with or without snap ring are available only on request.

Deep groove ball bearings tested for noise
As standard, deep groove ball bearings are subjected to noise tests up to bore parameter 12.

In addition, a 100 % rolling test is carried out. These bearings can also be subjected to a noise

test if required by the customer (on request only).

Cages
Deep groove ball bearings without cage suffix are provided with a steel sheet cage. Differing

cage designs are indicated at the bearing type as bearing symbol (suffix). Deep groove ball

bearings with cages of fiber-glass reinforced polyamide 66 are suitable for temperatures of

maximum 120 °C for longer periods of time. When using oil lubrication (for non-sealed bearings),

the additives contained in the oil may affect the period of use of the cage if the temperature

exceeds 100 °C for a longer period of time. In addition, deep groove ball bearings with brass

cage and current-insulated designs are available on request.

 

Single-row deep groove ball bearings accept radial and axial forces and can thus be used in a

wide range of applications. They have a simple design, are self-retaining, suitable for high up

to very high speeds and resistant in operation and during maintenance and they are offered

at a very favorable price. Due to these characteristics, self-aligning deep groove ball bearings

are the anti-friction bearings which are used most. The standard version of SLF deep groove

ball bearings is provided with a recess for inserting sealing and/or covering disks. The only

exception is series 160... . Here, only a version without sealing and/or covering disk can be

supplied. (Exception 16006.2ZR)
