6004-2RS Ball Bearing

The 6004-2RS Ball Bearing is a deep groove ball bearing engineered for equipment requiring continuous operation, improved lubrication protection, and dependable performance in compact medium-speed systems.

Its deep groove design supports smooth rotation and dependable mechanical stability, while double rubber seals (2RS) help protect internal grease from fine particles and moderate moisture. This combination makes the 6004-2RS a common choice for compact electric motors, industrial automation systems, and equipment operating continuously for extended periods.

Manufactured from chrome steel and supplied factory pre-lubricated, the bearing provides a balanced combination of durability, reduced operational noise, and lower maintenance requirements.

Common Applications for the 6004-2RS

The 6004-2RS is frequently used in compact equipment and rotating assemblies such as:

• Electric motors
• Automated equipment
• Industrial fans
• HVAC systems
• Power tools
• Small pumps
• Compact machinery
• Light material handling equipment

The 6000 series is recognized for versatility in compact industrial applications and dependable mechanical efficiency during continuous operation.
