SLGR ceramic bearings, your best choice!
Check out the characteristics of SLGR ceramic bearings and learn about the main reasons to choose them:
- Insulation: Good resistance to electricity and magnetism, not easily affected by electric and magnetic fields.
- High hardness: Compared with steel bearings, they are less susceptible to damage and deformation in some high pressure and high speed applications.
- Wear resistance: Ceramic balls have low density and high hardness, small particles that enter the bearing will be easily crushed.
- Corrosion resistance:Ceramics are not easy to rust or oxidation, and have good stability.
- High and Low Temperature Resistance: It can withstand temperatures from as low as (-85°C) to (+ 900°C).
- Low Friction: Ceramic bearings are hard, smooth and can be used without lubrication.
SLGR-specializes in the production of ceramic bearings
Compared with traditional bearings, ceramic bearings are more favored by manufacturers because of their advantages. SLGR is a leading manufacturer dedicated to providing high-quality ceramic bearings. The products are known for their excellent performance and reliability, providing a variety of ceramic bearings for different applications to meet the needs of different users.
Ceramic bearings can be divided into two types: full ceramic bearings and hybrid ceramic bearings. All-ceramic bearings are made entirely of ceramic materials, while hybrid ceramic bearings are generally made of a combination of ceramic and stainless steel materials.
SLGR’s ceramic materials are also diverse. Here you can find ceramic bearings made of silicon nitride (Si3N4), aluminum oxide (Al2O3), zirconium oxide (ZrO2), and silicon carbide (SiC).
Ceramic bearings by type
You can find cost-effective, diverse, and full series of ceramic bearings here. The main types are all-ceramic bearings and hybrid ceramic bearings. All-ceramic bearings can be subdivided into the following categories.
The rolling elements and inner and outer rings are entirely made of ceramic materials, usually made of aluminum oxide (Al2O3) or silicon nitride (Si3N4).
The contact angle between the inner and outer rings is designed to withstand radial and axial loads and is often used in extreme special environments.
Made entirely of ceramic material. Configuration retainers can also be made of composite materials and are mainly used to withstand axial loads.
There is a certain alignment angle between the inner ring and the outer ring, which can automatically adjust the deviation.
The bearing’s inner and outer rings have conical raceways, and the bearing can bear both radial and axial loads and is entirely made of ceramics.
There are single-row, double-row and multi-row rolling elements. The rollers and raceways are in line contact and are suitable for applications under high-speed rotation and heavy load conditions.
It is a ceramic ball bearing with a flange, and the flange is used to help the bearing hold its position better.
The rolling elements are made of ceramic materials, and the inner and outer rings are made of metal materials. The design combines the advantages of ceramic bearings with the strength of metal bearings.
Ceramic bearings by Material
Here you will also find some ceramic bearings with rolling elements made of the following materials.
Alumina (Al2O3) ceramic bearingsAlumina ceramics have good wear and corrosion resistance, and bearings made from them are often used in general applications and are known for their excellent performance.
Silicon Nitride (SiN4) Ceramic BearingsThe material has higher hardness and wear resistance and is suitable for higher rotation speed and load-bearing capacity, high temperature and high speed applications.
Zirconia (ZrO2) ceramic bearingsThis material has the advantages of anti-electricity and magnetism, wear resistance and corrosion resistance, and does not require self-lubrication. It is usually suitable for extremely harsh environments and special working conditions.
Silicon Carbide (SiC) Ceramic BearingsSilicon carbide has ultra-high chemical resistance, higher hardness, and greater wear resistance, making it generally suitable for high-temperature applications and extremely corrosive environments.

Let’s explore the wonders of ceramic bearings with you
Compared to steel bearings, you’ll find that ceramic bearings reduce rolling resistance. Make sure the applied load is evenly distributed on all rolling parts without putting stress on the balls or races. And the friction coefficient of ceramic materials is low, making the equipment rotate faster and operate more efficiently. Ceramic bearings are also harder, making them more durable and last longer than steel bearings. And because of their insulating properties, they will not corrode or rust.
When purchasing ceramic bearings, one thing everyone will notice is that they are more expensive than metal bearings. SLGR ensures that its products meet the highest standards to provide you with superior quality and reliability. They are rigorously tested when manufactured. Ceramics are extremely sensitive to impurities in their gaps, so a clean environment and skilled production processes must be ensured during the manufacturing process. Of course, these additional costs will be offset, and the stability of ceramic bearings can reduce everyone’s maintenance costs.
SLGR's ceramic bearings are widely used in various industries
Ceramic bearings are widely used in the aerospace industry because of their light weight, high temperature resistance, wear resistance and vacuum compatibility.
Due to their excellent corrosion resistance, ceramic bearings provide perfect solutions in some corrosive environments such as chemical manufacturing and medical equipment.
Due to the excellent wear resistance and high-speed capabilities of ceramic bearings, they are not easily damaged and deformed in some high-pressure and high-speed applications.

SLGR’s vehicle manufacturer customers use ceramic bearings in road and mountain bikes. Our ceramic ball bearings are lightweight and can increase vehicle speed, acceleration, and durability. And the thermal properties of ceramic bearings can prevent heat accumulation due to friction, thereby achieving smooth and fast driving of the vehicle.
The maximum speed of ceramic bearings is 20%-25% lower than that of steel bearings. Therefore, at higher speeds, ceramic bearings are prone to cracking and failure.
Compared with steel bearings, ceramic bearings are superior in high temperature resistance and corrosion resistance. Steel bearings win because of their load and speed ratings.
The service life of ceramic bearings is generally 5-20 times that of traditional bearings.
All-ceramic bearings are carefully designed to have strong corrosion resistance and can be used in corrosive environments for a long time.
Not only because of the excellent performance advantages of its products, but also because SLGR can provide professional services and technical solutions every time.

What are ceramic bearings?
The design of ceramic bearings is similar to that of steel bearings, the only difference in design is the material. Ceramic bearings are ideal for applications with high loads, high speeds and extreme environments.
When to choose ceramic bearings?
When choosing ceramic bearings, you usually need to consider the following factors:
- When your mechanical speed needs to be upgraded
- Applications with high loads, high speeds and extreme temperature differences
- Selected in applications where conductivity is a concern
All-ceramic bearings are made entirely of ceramic materials. Hybrid ceramic bearings are generally made of ceramic balls with metal outer rings and inner rings.
