FAQ

What does the C3 designation mean?

C3 indicates increased radial internal clearance, allowing the bearing to compensate for thermal expansion and operate reliably at higher temperatures and rotational speeds.

Is the NTN 6204 C3 suitable for electric motors?

Yes. It is widely used in electric motors, industrial drives and other high-speed rotating equipment.

Does the standard NTN 6204 C3 include seals?

No. This version is supplied as an open bearing intended for externally lubricated applications.

What types of loads can this bearing support?

It supports high radial loads together with moderate axial loads acting in both directions.

Can the NTN 6204 C3 replace equivalent bearings from other manufacturers?

Yes. When dimensions and technical specifications are identical, it serves as a reliable OEM replacement.
