6204-ZZ Ball Bearing C3 Clearance

The 6204-ZZ Ball Bearing C3 Clearance is a deep groove ball bearing engineered for industrial applications requiring high-speed stability, lower friction, and improved thermal compensation during continuous-duty operation.

Measuring 20x47x14mm, this bearing combines double metal shields (ZZ) with C3 internal clearance, making it ideal for electric motors, transmission systems, and equipment operating under elevated RPM and operating temperatures. Manufactured from chrome steel and supplied factory pre-lubricated, the bearing delivers smooth rotation, strong mechanical efficiency, and dependable industrial durability.

Applications for the 6204-ZZ C3

The 6204-ZZ C3 is widely used in industrial systems operating under high rotational speed and moderate thermal expansion, including:

• Industrial electric motors
• Pumps and compressors
• Industrial fans
• Gearboxes
• Agricultural machinery
• Automated equipment
• Conveyor systems
• Alternators and generators

C3 clearance bearings are commonly selected for applications where operational heat creates internal expansion during continuous use.
