20×47×14 Full Ceramic Bearing Solution for Demanding Industrial Applications
CE-1204-ZZPE is a zirconia (ZrO₂) full ceramic deep groove ball bearing with a 20 mm bore diameter, 47 mm outside diameter, and 14 mm width. Designed with a cage-free full complement structure, this ceramic bearing is suitable for applications requiring corrosion resistance, electrical insulation, clean operation, and reduced maintenance requirements.
The bearing features:
Zirconia ceramic inner ring
Zirconia ceramic outer ring
Zirconia ceramic balls
Cage-free full complement design
Unlike hybrid ceramic bearings that combine ceramic balls with steel rings, CE-1204-ZZPE contains no metallic components, making it suitable for environments where conventional steel bearings may face corrosion, conductivity issues, or contamination risks.
Typical applications include:
Chemical processing equipment
Laboratory instruments
Cleanroom automation systems
Semiconductor equipment
Precision machinery
Specialized non-metallic bearing applications

| Dimensional Reference | 6004 size (20×47×14 mm dimension) |
| Ceramic Model Number | CE-1204-ZZPE |
Note:
The 6004 reference is provided for dimensional comparison only. CE-1204-ZZPE is a zirconia full ceramic bearing model and is not an original steel 6004 bearing designation.
CE-1204-ZZPE uses zirconia ceramic for the main bearing components, providing:
Corrosion-resistant performance
Electrical insulation capability
No steel rust contamination
Compatibility with clean and demanding environments
The cage-free full complement structure allows more ceramic balls to be incorporated compared with conventional caged designs.
Key benefits:
Higher stiffness
Improved load distribution
Suitable for applications requiring static load capability
Engineering consideration:
Due to direct ball-to-ball contact, full complement bearings generally have higher friction than caged designs. For high-speed applications, caged ceramic or hybrid ceramic bearings may provide a more suitable solution.
CE-1204-ZZPE is designed for equipment requiring:
| Operating Requirement | Application Examples |
|---|---|
| Corrosion resistance | Chemical equipment, fluid handling systems |
| Electrical insulation | Semiconductor equipment, high-voltage mechanisms |
| Clean operation | Laboratory equipment, cleanroom automation |
| Non-metallic bearing structure | Specialized industrial machinery |
| Performance Item | Reference Value |

CE-1204-ZZPE has a 20 mm bore diameter, 47 mm outside diameter, and 14 mm width.
CE-1204-ZZPE is a full ceramic bearing. The inner ring, outer ring, and rolling elements are all manufactured from zirconia ceramic.
CE-1204-ZZPE has the same basic dimensional reference as a 6004 size bearing (20×47×14 mm). Application compatibility should be evaluated according to load, speed, and installation requirements.
Zirconia ceramic bearings are commonly selected for applications requiring corrosion resistance, toughness, and electrical insulation.
Silicon nitride ceramic bearings are generally preferred for higher-speed operation, higher temperature capability, and demanding precision applications.
Full ceramic bearings provide advantages for corrosion resistance, electrical insulation, and non-metallic applications.
Hybrid ceramic bearings combine ceramic balls with steel rings and are generally selected when higher speed capability and dynamic performance are required.
Some applications allow dry operation. Lubrication requirements depend on speed, load, temperature, and operating environment.
Yes. Customized clearance, lubrication, and special ceramic bearing designs are available according to application requirements.
