Full Ceramic and Ceramic Hybrid Bearings

Ceramic Hybrid Bearings


 


Ceramic Hybrid Bearings have Steel races and Ceramic Balls. Ceramic Balls are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel. In ball form, ceramic balls are also harder than steel and because ceramic balls are non-porous they are virtually frictionless and capable of spinning faster than steel balls.

 

Ceramic Balls are usually made of following materials:

 

  • Silicon Nitride (SiN4)
  • Alumina Oxide (Al2O3)
  • Zirconia Oxide (ZrO2)
  • Silicon Carbide (SiC)


Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction. Ceramic balls require less lubrication and have a greater hardness than steel balls which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speeds.

 

 

Ceramic Hybrid Bearing Benefits

 

  • High loads, high speeds and extreme temperatures are factors
  • Increased bearing life and decreased down time
  • Minimal need for lubrication
  • No cold welding between ceramic balls and races
  • Multi-purpose use in variety of machines and different production lines
  • High efficiency, low weight and small size

 

Ceramic Hybrid Bearing Applications

 

Ceramic hybrid bearings are widely used in electric motors, aerospace applications, performance racing vehicles, laboratory equipment, under water applications and more. Any application that requires higher speeds, lower friction and longer life are ideal for ceramic hybrid bearings.

 

Ceramic Hybrid Bearing Styles and Sizes

 

Ceramic hybrid bearings are available in variety of sizes and styles:

 

 

Radial Bearings

The purpose of a radial bearing is to reduce rotational friction and support loads. This is achieved by using two races to hold the balls and to spread the load through the balls. As the bearing race rotates it causes the balls to rotate. The ball provides for substantially less rolling resistance and coefficient of friction than if two flat surfac ...

Angular Contact Bearings

Angular contact bearings are designed such that there is an angle between the races and the balls when the bearing is in operation. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that o ...

Dental Tool Bearings

There are two basic types of dental ball bearings depending on the type of work that the tool is designed for. The first type is the Radial Bearing and the second type is the Thrust Bearing. Radial Bearings are designed for working in deep grooves and for angled dental surfaces. Radial Bearings have an inner ring, an outer ring, a series of balls a ...

Insert Bearings

Insert bearings and wide inner ring bearings are used for mounting on shafts without the need for shoulders or adapters. The bearing is locked in place through setscrews or a locking collar. UC Style Insert Bearings have an inner ring that extends on both sides of the bearing and SB Style Insert Bearings extend on one side. Both designs however are ...

Balls

Starting from the rigorous testing of the wire for all crucial factors, balls are produced in specifically designed machines called Headder, Flasher, Grinder and Lapper. Heat treatment is one of the most important operations that give required strength & hardness to the balls. Heat treatment makes the balls tough and wear resistant. Different mater ...

Full Ceramic Bearings

 

Full Ceramic Bearings have races and balls that 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.

 

Full Ceramic Bearings are usually made of following materials:

 

  • Silicon Nitride (SiN4)
  • Alumina Oxide (Al2O3)
  • Zirconia Oxide (ZrO2)
  • Silicon Carbide (SiC)

 

Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction. Ceramic balls require less lubrication and have a greater hardness than steel balls which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speeds.

 

 

Full Ceramic Bearing Benefits

 

  • Will not corrode or rust
  • 2/3 the weight of steel
  • Resistant to resist acids, alkali, blood, salt and water
  • Extremely low coefficient of friction and thermal expansion
  • Lower friction results in less energy consumed
  • Operating Temperature from as low as (-85°C) up to (+ 900°C)

 

Full Ceramic Bearing Applications

 

Full Ceramic bearings are used in specialty applications like chemical baths, vacuum environments, semiconductor manufacturing, food processing industries, radiotherapy, MRI, patient positioning systems and more. Any extreme environment that requires non-corrosive, non-conductive or non-magnetic bearings is ideal for full ceramic bearings.
