In addition to common ceramic bearing codes, there are also some specialized codes used for special types of ceramic bearings. Here are some examples:
1. Hybrid bearing: This is a type of bearing that combines ceramic balls and steel rings, commonly referred to as Hybrid. It possesses the high-temperature and high-speed performance of ceramic bearings, as well as the strength and toughness of steel bearings.
2. Full Ceramic bearing: This is a type of bearing made entirely of ceramic material, including the inner ring, outer ring, and rolling element, all made of ceramic material. The commonly used code for this type of bearing is Full Ceramic.
3. SiC bearing: This is a type of bearing made of silicon carbide ceramic material, commonly referred to as SiC. It has excellent friction resistance and wear resistance, suitable for high temperature and corrosive environments.
4. ZTA bearing: This is a type of bearing made of aluminum oxide and titanium nitride composite ceramic material, commonly referred to as ZTA. It has high wear resistance and strength, suitable for high-speed and high load operation.
5. ATC bearing: stands for "Air Turbine Ceramic Bearing", which is a special purpose ceramic bearing commonly used for high-speed air turbines.
6. HCR bearing: Representing "High Corrosion Resistance Bearing", this ceramic bearing has high corrosion resistance and is suitable for some corrosive environments.
7. DNJ bearing: stands for "Dynamic Nano Joint Bearing", which is a ceramic bearing manufactured using high-tech technology and has excellent dynamic performance and lifespan.
8. UHPL bearing: stands for "Ultra High Precision and Longevity Bearing", which is a ceramic bearing with high precision and long lifespan, suitable for instruments and equipment.
9 SR bearings: Representing "Surgical/Medical Grade Bearing", this ceramic bearing has high material purity and sterility, and is suitable for medical instruments and equipment.
10. CER bearing: stands for "Ceramic Electrical Resistance Bearing", which has good electrical insulation performance and is suitable for high-temperature and high-voltage electrical equipment.
11. HTB bearing: Representing "High Temperature Bearing", this ceramic bearing has excellent high-temperature resistance and can operate in high-temperature environments.
12. MLC bearing: Representing "Micro Lubricated Ceramic Bearing", this ceramic bearing has micro lubrication function, reducing lubrication requirements and friction losses.
(I/O) is the inner/outer ring of the bearing, (B) is the rolling element, (R) is the cage, and (C) is the sealing ring.
The cage, rolling element, and seal of ceramic bearings are usually represented by the following codes:
1. Holder:
-CA: represents copper alloy cage (commonly used in high-speed applications);
-PA: represents polyimide cage (with high heat resistance);
-PTFE: represents polytetrafluoroethylene cage (with good low friction and chemical stability);
-PEEK: stands for polyether ether ketone cage (with excellent heat resistance, mechanical properties, and chemical resistance).
2. Rolling element:
-ZrO2: represents zirconia ceramic rolling element;
-Si3N4: represents silicon nitride ceramic rolling element;
-Al2O3: represents alumina ceramic rolling element;
-SiC: represents silicon carbide ceramic rolling element.
3. Sealing:
-RS: represents unidirectional sealing;
-2RS: represents bidirectional sealing;
-ZZ: represents metal dust cover sealing;
-LLB: represents non-contact rubber seal.
These codes are generally used to identify the cage, rolling element, and sealing type of ceramic bearings, in order to distinguish them during selection and purchase. Please note that different manufacturers and types of ceramic bearings may use slightly different codes. It is recommended to consult relevant technical specifications and manufacturer provided information before purchasing to confirm accurate codes and performance characteristics.
Please note that these codes are only examples, and the actual ceramic bearing codes may vary depending on the manufacturer and specific application. When purchasing ceramic bearings, consult Shanghai Anding Yitai ceramic bearing manufacturer 136-2180-8094
