Product Description
629 2RS Full ZrO2 ceramic bearing for alternator
Features of 679 689 699 609 629 639 ZZ 2RS ceramic bearing
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 roller 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.
What is the advantage of Ceramic ball bearings?
Ceramic bearings have the normal steel balls replaced by white ceramic balls. The ceramic balls are made of solid silicon nitride.
Ceramic silicon nitride balls are called ceramic but have nothing in common with household dish ceramics. They are called ceramic because it's easier calling them ceramic then silicon nitride. The ceramic silicon nitride ball is by far, smoother, harder, lighter and stronger than one made off steel.
Full Ceramic bearing Design Attributes :
Design combines ceramic rolling elements with super finished steel rings to run faster, cooler and longer.
Advanced design and materials help improve rigidity while reducing noise, vibration and operating temperature.
Can be ordered with or without seals.
Expanded options include custom preloads, 15° or 25° contact angles, and designs to ISO/ABMA 02, 10, 19 specifications.
Advantages of Ceramic Bearings
essentially increased life time
high stiffness because of high Young’s modulus,lower vibration
wear resistance and cost effective lubrication
electrical insulation and non-magnetism
high temperature resistance up to 1000oC
high corrosion resistance to most acids and alkalies
Hybrid Ceramic Bearing:
Ceramic bearings offer a significant performance improvement from those made from traditional steel. Our ceramic bearings are manufactured from silicon nitride (Si3N4), an exceptionally hard non-metallic material rated for speeds to 2 million dN, offering a wide selection of benefits.
Hybrid Bearings have steel rings and ceramic balls. Si3N4 Ball is the most popular for the balls as it has only 40 percent of the density of bearing steel but is much harder giving greater wear resistance. Zirconia is heavier with 75 percent of the density of steel so is less suitable for hybrid bearings..
Full Ceramic Bearing :
Full Ceramic Bearings are made entirely of ceramic material and are superior to common steel 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. Applications such as cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics and optics. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), or Silicon Carbide (SiC.)
Ceramic Balls:
We are special in making Silicone Nitride Balls (Si3N4 Balls,Zicronia Balls (ZrO2 Balls),Sic Ceramic Balls , Aluminum Oxside Valve (AI203) ceramic balls.
Compared with steel, ceramic materials are noted for their better or particular characters, such as wear-resistance, corrosion resistance, high temperature resistance, electrical insulation (except SiC), non-magnetic, high strength, high rigidity, and low specific gravity. These properties qualify them for replacing steel to make bearings serve in conditions of higher speed, harsh environment and less lube, and decrease wear, noise, vibration and maintenance time of bearings, and eventually increase performance, reliability and life of bearings.
Higher hardness of rolling element | - Better wearability |
- Greater durability | |
- Longer service life | |
Lower gravity | - Lightweighting the system |
- 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 system |
- 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 |
Electrical isolation | - No galvanically stimulated corrosion |
- Can be used in applcation that requires electrical isolation |
