6304 2RS PPL Deep Groove Ball Bearing 20x52x15

Double Sealed Bearing Designed for Long Service Life in Industrial Machinery

The 6304 2RS PPL Deep Groove Ball Bearing 20x52x15 is engineered for industrial equipment requiring effective contamination protection, low maintenance and dependable rotational performance. Equipped with double rubber seals (2RS), the bearing retains factory grease while preventing dust, moisture and other contaminants from entering the raceways. The larger 6300 bearing series provides increased radial load capacity, making this model particularly suitable for heavier industrial applications compared with the 6200 series.

Natural entity coverage includes deep groove ball bearing, sealed ball bearing, radial ball bearing, rolling bearing, 2RS bearing, electric motor bearing, gearbox bearing, industrial bearing, transmission bearing and OEM replacement bearing.

FAQ

What does the 2RS designation mean?

The 2RS suffix indicates rubber seals on both sides of the bearing, protecting internal grease while preventing dust and moisture from entering.

Is the bearing supplied pre-lubricated?

Yes. The bearing is factory-greased and ready for installation without additional lubrication under normal operating conditions.

Why choose the 6300 series instead of the 6200 series?

The 6300 series has a larger cross-section and generally offers higher radial load capacity, making it suitable for heavier industrial applications.

Can this bearing be used for OEM replacement?

Yes. The standardized dimensions of 20x52x15 mm allow it to replace compatible 6304 bearings when the original technical specifications match.
