6204 ZZ C3 FAG Ball Bearing

Industrial Applications

ZZ Metal Shields and C3 Clearance

Bearing Unit for Bearing Housings

Main Description

The 6204 ZZ C3 FAG ball bearing 20x47x14 mm is a precision single-row deep groove ball bearing designed for reliable operation in demanding industrial applications. This bearing unit is engineered for stable performance at higher rotational speeds and under variable thermal conditions, making it suitable for continuous-duty machinery.

The increased internal clearance C3 allows for thermal expansion during operation, reducing internal stress and significantly improving bearing life. Double metal shields (ZZ) protect the internal components from dust and fine contaminants while maintaining low rolling resistance. This design ensures smooth operation, low noise levels, and minimal maintenance requirements.

With standardized dimensions of 20x47x14 mm, the 6204 ZZ C3 bearing integrates easily into common bearing housings and mechanical assemblies. It is widely used in electric motors, gearboxes, pumps, fans, conveyors, and industrial drive systems. The deep groove design enables the bearing to carry radial loads as well as moderate axial loads in both directions, ensuring versatility across multiple industrial sectors.

Manufactured to strict quality standards, this ball bearing offers high durability, consistent geometry, and predictable performance. As a professional bearing unit from FAG, it is a trusted solution for B2B customers who require long service life, operational stability, and reduced downtime in industrial environments.

FAQ - Frequently Asked Questions

What does ZZ mean in a ball bearing?
ZZ indicates double metal shields that protect the bearing from contamination while retaining lubrication.

Why is C3 internal clearance important?
C3 clearance allows safe operation at higher speeds and temperatures by compensating for thermal expansion.

Can this bearing be used in a bearing housing?
Yes, it is fully compatible with standard bearing housings and bearing units.

What loads can the 6204 ZZ C3 bearing handle?
It supports radial loads and moderate axial loads in both directions.

Does the bearing require additional lubrication?
No, it is factory-lubricated and ready for installation.
