Main Description
The KOYO 6003 2RS C3 17x35x10 is a versatile sealed deep groove ball bearing, designed for applications where compact dimensions and protection against dust or contaminants are essential. It combines rubber seals on both sides (2RS) with a larger-than-normal internal radial clearance (C3) to afford better tolerance to thermal expansion and slight misalignments.
Applications & Use Cases
This bearing is suitable in many industrial, electromechanical, and machinery systems. Typical uses include:
-
Electric motors and pumps
-
Gearboxes and transmission units
-
Fans, blowers, ventilation systems
-
Precision machinery, automated equipment
-
Robotics joints, actuators, small drives
-
Agricultural machinery, conveyors, machine tools
Many designers favor the 6003 size (17 x 35 x 10 mm) for its balance of load capacity and compactness. The 2RS sealing helps protect the bearing in moderately contaminated environments, while the C3 clearance ensures safe operation under temperature variations and minor shaft expansions.
Key Features & Advantages
-
Double rubber seals (2RS): protect inner components from dust, dirt, and light moisture, while retaining lubricant
-
Internal clearance C3: greater than normal, helps prevent binding under thermal expansion or slight shaft misalignment
-
Sealed and pre-lubricated: bearing arrives ready for installation, reducing maintenance needs
-
Low friction design: despite the sealing, the bearing maintains efficient operation at speed
-
Reliable material and build: produced by KOYO, known for quality in bearing manufacturing
-
Dimensional compatibility: 17 x 35 x 10 mm is a common format, simplifying replacement and integration
Quality Bearings Online lists dynamic load rating ~6.0 kN and static rating ~3.25 kN for this model.
KOYO’s official spec page (for 6003 2RS) shows matching boundary dimensions and technical parameters.
Technical Data & Performance
| Parameter | Value / Notes |
|---|---|
| Bore (d) | 17 mm |
| Outer diameter (D) | 35 mm |
| Width (B) | 10 mm |
| Seal type | 2RS (double rubber seals) |
| Internal clearance | C3 (larger than standard) |
| Basic dynamic load (Cr) | ~7.50 kN (for 6003 2RS) |
| Basic static load (C₀r) | ~3.25 kN |
| Limiting speed (grease) | ~12,000 min⁻¹ according to KOYO spec |
| Minimal chamfer radius (rₘᵢₙ) | 0.3 mm |
| Mass | ~0.039 kg (39 g) |
| Temperature range | typically -30 °C to +120 °C (depending on grease and seals) |
| Load type | Primarily radial loads; limited axial load support |
Given its C3 clearance, this bearing is better suited for applications where temperatures rise or the shaft expands slightly under load. The 2RS seals provide a balance between protection and performance.
FAQ
1. What does “2RS C3” mean?
“2RS” indicates the bearing has two rubber seals (one on each side). “C3” implies a higher internal radial clearance than standard, accommodating thermal expansion.
2. Can this bearing work in dusty or humid environments?
Yes — the rubber seals provide protection against dust and light moisture. For more extreme or wet conditions, fully shielded or stainless bearings may be preferable.
3. Does C3 clearance reduce bearing strength?
No — it does not reduce load ratings. It gives extra room internally so the bearing doesn’t jam under temperature fluctuations or slight misalignments.
4. Is the bearing pre-lubricated?
Yes, the KOYO 6003 2RS C3 typically comes factory-lubricated with grease and is ready for installation.
5. What is the typical speed limit?
For the 6003 2RS, KOYO’s spec lists about 12,000 rpm when greased. Actual safe speed depends on load, alignment, and lubrication.
