Smooth rotation with Skf bearing

Practical benefits

Protection against external dirt: Dual rubber contact seals retain lubricant and protect your bearing against moisture, debris, and fine dust.
Optimized for high speeds: The increased C3 radial clearance helps you accommodate thermal expansion effortlessly during high-temperature or fast-rotating operations.
Low vibration performance: You support both radial and axial loads smoothly while benefiting from minimal running friction and quiet mechanical operation.

In a nutshell

The right choise for

With the Skf 6004-2RSH/C3 deep groove ball bearing, you ensure smooth and reliable rotation for electric motors, pumps, and industrial drive systems. The dual 2RSH rubber contact seals retain factory grease while keeping dust, debris, and moisture out to extend service life. Thanks to the increased C3 radial clearance, the bearing effortlessly accommodates thermal expansion during high-speed operations or tight interference fits, preventing seizing. It supports both radial and axial loads in both directions with minimal running friction and low vibration. This pre-lubricated bearing keeps your equipment running smoothly without requiring periodic maintenance.
