Detailed introduction to ceramic yoyo bearing 6315 C3

ceramic bearing

Cost performance ceramic bearings are far superior to steel bearings, lifetime use of bearing life

than now increased more than 3 times, can save a lot of downtime downtime, reduce scrap, reduce

spare parts inventory bearings. Performance comparison with the bearing steel, bearing steel weight

is 30% -40%, can reduce the centrifugal force generated by the increase in dynamic physical load

and slip. Because of high wear resistance, speed is 1.3-1.5 times the bearing steel, high-speed

rotation can reduce the channel due to surface damage.

Elastic modulus 1.5 times higher than the bearing steel. Elastic force is small, can reduce the load

generated by the high amount of deformation. Hardness is 1 times the bearing steel, can reduce the

wear and tear. Compressive strength is 5-7 times the bearing steel. Bearing steel thermal expansion

coefficient is less than 20%. Friction coefficient is less than 30% of bearing steel, can reduce friction

and heat, reduce heat caused by bearing failure before peeling. Tensile, bending and metal

equivalent.

ull ceramic bearing of ZrO2 materia characteristics:1) Chemical resistant. Can work in various

chemicals.2)

No need lubrication, clean, and can wash in the water.3) Non-magnetic and insulation. Reliable

working.4) Constant working in high temperature till 250 Centigrade by choosing different cage.5)

High speed.6) Light weight.7) Outstanding long time working in low temperature till -80

centigrade.8) Tolerance is as per normal bearings. Easy for assembly. Application is as under:

Electro plating, electro polishing ,

Food processing, vacuum applications.Fiber processing, conveyor processing. Medical radiation,

photo processing,Computer assembly, electronics applications, Medicine equipment, wet

applications

ceramic yoyo bearing 6315 C3 Features:
1) Ceramic bearings have excellence performance as special electrical and magnetism resistance, wear and corrosion resistance, lubrication and maintenance free when working, high and low- temperature resistance etc. So they are suitable to be used in awful environment and special condition.
2) The rings and balls made of full ceramic material: ZrO2, SisN4 and Sic as a standar structure,

the cage made of PTFE, GFRPA66-25, PEEK, PI, AISI US304, SUS316,Cu, etc.
3) Series available: single-row deep groove ceramic ball bearings, self-aligning ceramic ball bearings, single direction thrust ceramic ball bearings and angular contact ceramic bearings
4) Ceramic balls: all kinds of ceramic balls with the precision from G5 to G200,made of the material ZrO2, SiN4, SiC and Al2O3, etc.

ceramic yoyo bearing 6315 C3 Applications :
auto manufacture,driving equipments and engine industrial,chemistry industrial,medical industrial

and food processing equipments industrial and so on.

ceramic bearing 6308 Ceramic Ball Bearing,This type of bearings have High degree of standardization, and the Structural alterations to the machine tool is small, Ease to maintenance, Particularly suitable for high speed running applications.ceramic bearing 6308, Its assembly high-speed spindle has High-speed, high stiffness, high power, long life and other advantages.

bear high temperature: the Thermal expansion coefficient of the Ceramic ball is little, so the high temperature will not make expansion of the ball bearing in the high temperature environment, This greatly improves the bearing working temperature, the general bearing working temperature is

about 160 degree, but the Ceramic Ball Bearing working temperature will higher than 220 degree. high speed: Ceramic ball has a self-lubricating oil properties, and the Friction coefficient is small, so the ceramic ball bearing have high running speed about 1.5 Multiple to general bearing. Insulation:

Finally the insulation, ceramic ball bearings, the bearing's inner and outer rings can be insulated

from each other, ceramic bearing 6308 this is the most importantly feature of this type bearings.
