6003-2RSL/C3 Bearing Product Overview & Core Advantages
The 6003-2RSL/C3 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while its sealed construction ensures long-term performance by protecting against contamination. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers a robust balance of precision and durability. The combination of a C3 radial internal clearance makes it particularly suitable for applications where thermal expansion is a factor, ensuring stable operation across its specified temperature range.
6003-2RSL/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 6003: Basic model number denoting a metric, single row deep groove ball bearing with a 17mm bore, 35mm OD, and 10mm width.
- 2RSL: Signifies that the bearing is equipped with two (2) low-friction synthetic rubber contact seals (RSL) on both sides, providing superior protection against contaminants and moisture.
- C3: Indicates a radial internal clearance greater than the Normal (CN) group. This is ideal for applications with expected temperature gradients or where fits result in a reduction of internal clearance.
6003-2RSL/C3 Bearing Structural Features & Performance Benefits
Robust Construction & High Load Capacity: Built entirely from chrome steel for rings, balls, and cage, this bearing delivers high strength and resistance to wear. Its deep groove raceway geometry is optimized for high radial dynamic load ratings (1349 lbf) and radial static load ratings (731 lbf).
Enhanced Sealing & Contamination Resistance: The 2RSL contact seals are a critical feature, effectively shielding the internal components from dust, dirt, and moisture. This significantly extends the bearing's service life and reduces the need for maintenance in harsh environments.
Optimized for Stable Operation: The C3 clearance provides operational stability in applications where bearing temperatures may rise significantly, preventing pre-load and potential seizure. This makes it a reliable choice for a wide temperature range of -30°C to 120°C.
6003-2RSL/C3 Bearing Typical Application Areas
The 6003-2RSL/C3 is a versatile component found in a wide array of machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Conveyor Systems
- Agricultural Machinery
- Automotive Components (e.g., alternators, water pumps)
