6004-2RS Deep Groove Ball Bearing
Sealed Ball Bearing for Electric Motors, Pumps and Industrial Equipment
The 6004-2RS deep groove ball bearing is designed for applications requiring reliable performance, low maintenance, and effective protection against dust and moisture. Equipped with rubber seals on both sides, it helps retain lubricant while reducing the risk of contamination entering the bearing during operation.
As one of the most commonly specified bearings in industrial machinery, the 6004-2RS is widely used in electric motors, agricultural equipment, water pumps, conveyors, automotive systems, and general power transmission applications.
Manufactured from high-quality chrome steel and finished through precision grinding processes, our bearings provide stable operation, consistent dimensional accuracy, and dependable service life under demanding working conditions.
Why Choose 6004-2RS Bearings?
Enhanced Sealing Performance
Double rubber seals help prevent dust, dirt, and moisture from entering the bearing, making it suitable for environments where contamination may shorten bearing life.
Ready for Installation
Each bearing is pre-lubricated with high-quality grease, reducing installation time and simplifying maintenance requirements.
Smooth and Quiet Operation
Precision raceways and controlled internal geometry contribute to low vibration and reduced operating noise.
Versatile Load Capability
The deep groove design allows the bearing to accommodate radial loads as well as moderate axial loads from both directions.
Cost-Effective Long-Term Performance
With proper installation and operating conditions, the 6004-2RS bearing offers an excellent balance between performance, durability, and operating cost.

6004-2RS vs 6004-ZZ
| Feature | 6004-2RS | 6004-ZZ |
|---|---|---|
| Seal Type | Rubber Seals | Metal Shields |
| Dust Protection | Excellent | Good |
| Moisture Protection | Excellent | Limited |
| Running Friction | Slightly Higher | Lower |
| High-Speed Capability | Good | Better |
| Maintenance Frequency | Lower | Standard |
For dusty or humid environments, the sealed version is generally preferred. For cleaner environments and higher rotational speeds, shielded bearings may be considered.
FAQ
What does 2RS mean on a 6004 bearing?
2RS indicates that the bearing is fitted with rubber seals on both sides. These seals help retain lubricant and prevent contaminants from entering the bearing.
Is the 6004-2RS bearing supplied with grease?
Yes. Standard bearings are factory lubricated and ready for immediate installation.
Can the seals be removed?
The rubber seals can generally be removed if required for maintenance or inspection. However, removing the seals may affect contamination protection and lubrication retention.
What is the difference between 6004-2RS and 6004-ZZ?
The primary difference is the closure design. 6004-2RS uses rubber seals for better protection, while 6004-ZZ uses metal shields that offer lower friction and higher speed potential.
Is stainless steel available?
Yes. Stainless steel 6004 bearings can be supplied for applications where corrosion resistance is important.
Do you offer OEM packaging and branding?
Yes. We support customized packaging, laser engraving, private labeling, barcode labels, and branded cartons for distributors and equipment manufacturers.
What industries commonly use 6004-2RS bearings?
They are widely used in electric motors, pumps, agricultural machinery, HVAC systems, conveyors, industrial automation equipment, and general mechanical assemblies.
