Hybrid Ceramic Angular Contact Ball Bearings

Hybrid ceramic angular contact ball bearings are particularly suitable for high-speed, high-precision and long-life steel-ceramic hybrid bearings rolling elements (the inner and outer rings are made of metal). Generally, the inner and outer rings are made of bearing steel or stainless steel, and the ceramic balls can be made of ZrO2, Si3N4, or SiC.

With the development of the world economy, the machinery industry is progressing faster and faster. With the innovation of new technologies and new materials, hybrid ceramic ball bearings have been developed. The use of hybrid ceramic ball bearings has made up for the bearing steel material and all-ceramic bearings. The cost of chrome steel bearings are low level, but there is almost no corrosion resistance; all ceramic bearings have good corrosion resistance, but they are not impact resistant, and the price is relatively expensive.

Under such circumstances, the hybrid ceramic bearing was born. It not only has a certain corrosion resistance effect, the most important thing is that it has the self-lubricating effect of ordinary bearings, and the price is much lower than that of full ceramic bearings.

 

Hybrid ceramic bearings China


Hybrid ceramic angular contact ball bearings, especially silicon nitride ball hybrid ceramic bearings, have the characteristics of low density, high hardness, low friction coefficient, anti-magnetic and electrical insulation, wear resistance, self-lubricating and good rigidity, good acid and alkali resistance, self-lubricating Function, high temperature resistance above 300°C, high wear resistance, high speed greatly reduces rolling, friction and heat generation, long service life is 3 to 5 times that of all-steel bearings, light weight ceramic materials 60% lighter than steel, The elastic mold of the same rigid ceramic material is 50% higher than that of bearing steel.

 

Hybrid ceramic angular contact ball bearings are the same as ordinary chrome steel angular contact ball bearings, Its inner and outer ring raceways are relatively offset from each other in the direction of the bearing axis. This means that this type of bearing is designed to carry combined loads, that is, radial load plus axial load.

 

The axial load carrying capacity of angular contact ball bearings increases with the increase of the contact angle. In the radial plane, the angle between the line connecting the contact point of the steel ball and the raceway (that is, the direction in which the combined load is transmitted from one raceway to the other raceway) and the vertical line of the bearing axis.

 

Angular contact ball bearings can only bear axial load in one direction. This type of bearing usually needs to be adjusted relative to another bearing. Their bearing rings have two shoulders, high and low, and are inseparable.

 

Hybrid ceramic angular contact ball bearings are particularly suitable for high-speed, high-precision and long-life steel-ceramic hybrid bearings rolling elements (the inner and outer rings are made of metal). Generally, the inner and outer rings are made of bearing steel or stainless steel, and the ceramic balls can be made of ZrO2, Si3N4, or SiC.

 

Among them, Si3N4 has excellent comprehensive performance and has become the first choice material for steel-ceramic hybrid ceramic bearings. Hybrid ceramic angular contact ball bearings

Advantages of hybrid ceramic Angular Contact Ball bearings


Hybrid angular contact ball bearings (designation suffix HC) have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (ceramic). As ceramic balls are lighter and have a higher modulus of elasticity and lower coefficient of thermal expansion than steel balls, hybrid bearings can provide the following advantages:

  • Higher degree of rigidity

  • Higher speed capability

  • Reduced centrifugal and inertial forces within the bearing

  • Minimized stress at the outer ring rolling contacts at high speeds

  • Reduced frictional heat

  • Less energy consumption

  • Extended bearing and grease service life

  • Less prone to skid smearing damage and cage damage when subject to frequent rapid starts and stops

  • Less sensitive to temperature differences within the bearing

  • More accurate preload/clearance control

The Applications of hybrid ceramic bearings:

1. Car

For the bearings used in automobiles, the turbo charger bearings have the highest requirements for speed, which require the bearings to have good acceleration responsiveness, as well as low torque, low vibration and low temperature rise under high-speed rotation. Due to its low temperature rise during operation, it can reduce the amount of lubricating oil, so the oil stirring resistance is reduced, the bearing torque is reduced, and the speed is increased. In addition, rail vehicles also use it, and its durability and reliability under harsh conditions have been proven.

2. Motor

Electric motors can be used to achieve permanent insulation. When the motors are used for deceleration and energy-saving devices, internal leakage can cause arcing.

3. Aero Engine

In the fuel pump of an aero engine, it can work in liquid oxygen and liquid hydrogen for a long time. It has been proven that it will not be damaged after 50 launches.

4. Aircraft parts

The aircraft manufacturing industry has used ball screws equipped with ceramic balls for aircraft flap adjusters, and has also tried to use hybrid ceramic bearings in gas turbine engines.
