6003-2RS Ball Bearing 17×35×10mm
A Practical Bearing Choice for OEM Production and Maintenance Programs
For many industrial buyers, selecting a bearing is not simply about matching dimensions.
The real challenge is finding a component that can perform consistently across thousands of operating hours, remain available throughout a product lifecycle, and fit seamlessly into existing designs.
The 6003-2RS deep groove ball bearing has become a widely adopted solution because it meets these practical requirements. Its combination of compact dimensions, sealed protection, and broad application compatibility makes it a dependable option for both new equipment manufacturing and aftermarket replacement programs.
Why the 6003-2RS Remains One of the Most Specified Bearing Sizes
Unlike specialized bearing designs that serve niche applications, the 6003-2RS is found across numerous industries.
Its popularity comes from a balance of factors:
| Selection Factor | Benefit |
|---|---|
| Standardized Dimensions | Easy interchangeability |
| Double-Sealed Design | Reduced contamination risk |
| Compact Profile | Suitable for limited spaces |
| Wide Industry Adoption | Simplified sourcing |
| Factory Lubrication | Faster installation |
| Proven Design | Long-term reliability |
For purchasing teams, this often translates into lower sourcing risk and greater flexibility when managing inventory.

Typical Operating Environments
One reason the 6003-2RS remains widely used is its ability to perform across a broad range of operating conditions.
Dust-Prone Work Areas
The rubber seals help prevent particles from entering the raceway, reducing premature wear.
Intermittent Operation
For machinery that starts and stops frequently, proper lubrication retention helps maintain smooth performance.
Continuous Duty Equipment
Stable internal geometry and quality lubrication support long operating cycles.
General Industrial Conditions
The bearing performs effectively in environments where moisture, vibration, and variable loads are part of normal operation.
Common Equipment Using 6003-2RS Bearings
Rather than focusing on industries, it is useful to look at actual equipment categories.
| Equipment Type | Typical Function |
|---|---|
| Electric Motors | Shaft support |
| Water Pumps | Rotor positioning |
| Agricultural Equipment | Rotating assemblies |
| Conveyor Systems | Roller support |
| Ventilation Equipment | Fan rotation |
| Packaging Machinery | Motion transmission |
| Fitness Equipment | Drive mechanisms |
| Small Gearboxes | Load support |
The bearing's versatility allows OEMs to standardize components across multiple product lines.
Considerations for Replacement and Cross-Reference Projects
Many buyers source 6003-2RS bearings as replacements for existing equipment.
Key evaluation points often include:
Dimensional Compatibility
The 6003 series follows international standards, allowing interchangeability with many global brands.
Seal Performance
For applications exposed to dust or light moisture, sealed bearings often provide longer maintenance intervals.
Supply Continuity
Long-term availability is particularly important for equipment with extended service lives.
Consistent Batch Quality
Maintenance teams typically prefer bearings that deliver predictable performance across repeat purchases.
FAQ
What does "2RS" indicate?
2RS means the bearing is equipped with rubber seals on both sides. These seals help retain lubricant and reduce contamination from dust and moisture.
Is the 6003-2RS pre-greased?
Yes. Standard bearings are supplied with factory lubrication and can be installed immediately.
Can this bearing replace other major bearing brands?
In most cases, yes. The 6003-2RS follows internationally recognized dimensional standards and can often be used as a direct replacement, subject to application verification.
Is C3 clearance available?
Yes. Both standard clearance and C3 clearance versions can be supplied depending on operating requirements.
Can customized packaging be provided?
Yes. OEM packaging, private labeling, and custom branding options are available for distributors and manufacturers.
Are samples available before volume purchasing?
Absolutely. Samples can be supplied for testing, qualification, and approval purposes.
Looking Beyond Dimensions?
A bearing may only occupy a small part of a machine, but its impact on equipment uptime can be significant.
