6003 Bearing Product Overview & Core Advantages
The 6003 metric ball bearing is a single row deep groove ball bearing designed for outstanding performance in general industrial applications. Engineered with precision ABEC-1 tolerances and manufactured from high-grade chrome steel, this bearing delivers reliable operation and long service life. Its fundamental design enables it to primarily handle radial loads efficiently, while its compact dimensions (17mm bore, 35mm OD, 10mm width) make it ideal for space-constrained assemblies requiring a robust and cost-effective solution.
6003 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6003 | Standard model number for a metric, single row deep groove ball bearing with a 17mm bore, 35mm OD, and 10mm width. |
| Open (Seal Type) | The bearing is supplied without seals or shields, allowing for higher limiting speeds and easy relubrication. It requires a clean operating environment or external sealing. |
| CN (Clearance) | Specifies normal radial internal clearance, which is the standard group suitable for most common operating conditions. |
6003 Bearing Structural Features & Performance Benefits
- High-Grade Material Construction: Rings and balls made from chrome steel (GCr15) provide high hardness, wear resistance, and a long fatigue life. The stainless steel cage ensures excellent corrosion resistance and cage integrity.
- Optimized for Radial Loads: The deep groove raceway and single row design are engineered to provide superior performance under radial dynamic loads of up to 1349 lbf, making it a reliable choice for a wide range of applications.
- Precision Performance: Manufactured to ABEC-1 tolerance class, this bearing offers precise running accuracy, low noise, and low vibration, which is essential for smooth operation in electric motors and precision machinery.
- High-Speed Capability: The open design and robust construction contribute to a high limiting speed of 21,000 rpm, enabling use in demanding high-velocity scenarios.
6003 Bearing Typical Application Areas
This versatile 6003 bearing size is commonly specified in:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, water pumps)
