6304 2RS C3 MGK Deep Groove Ball Bearing 20x52x15

High-Performance Deep Groove Ball Bearing for Industrial Drive Systems

The 6304 2RS C3 MGK deep groove ball bearing is engineered for demanding industrial applications requiring reliable operation at high rotational speeds under combined radial and moderate axial loads. Equipped with double rubber seals (2RS), the bearing effectively protects internal components against dust, moisture and contaminants while retaining factory-applied grease. The increased C3 internal clearance allows stable operation at elevated temperatures and higher rotational speeds, making this bearing ideal for electric motors, industrial drives and heavy-duty machinery.

FAQ

What does the 2RS designation mean?

2RS indicates that the bearing is fitted with rubber contact seals on both sides to protect against contamination and retain lubricant.

What is the purpose of C3 internal clearance?

C3 indicates greater-than-normal internal clearance, allowing reliable operation at higher temperatures and rotational speeds.

Is the 6304 2RS C3 bearing suitable for electric motors?

Yes. The combination of low friction, C3 clearance and effective sealing makes it ideal for electric motor applications.

Can this bearing support axial loads?

Yes. Deep groove ball bearings support high radial loads together with moderate axial loads acting in both directions.

Is 6304 2RS C3 MGK suitable as an OEM replacement?

Yes. Its ISO-standard dimensions and professional construction make it an excellent OEM replacement for a wide variety of industrial and automotive applications.
