6003/C4 Bearing Product Overview & Core Advantages
The 6003/C4 is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. As a metric bearing with an open design, it excels in handling primarily radial loads and offers high-speed capabilities. A key feature is its specified C4 radial internal clearance, which makes it particularly suitable for applications involving thermal expansion, such as in electric motors, where shaft and housing fits can generate significant operational heat. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution without compromising on essential precision and durability.
6003/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6003 | Standard bearing series designation indicating a 17mm bore, 35mm OD, and 10mm width. | Defines the core bearing dimensions for easy identification and interchangeability. |
| /C4 | Specifies a greater than normal radial internal clearance. | Accommodates thermal expansion in applications with high operating temperatures or interference fits, preventing premature failure due to binding. |
6003/C4 Bearing Structural Features & Performance Benefits
- Open Seal Type & High-Speed Performance: The open construction minimizes friction, allowing the bearing to achieve a high limiting speed of 21,000 rpm. This is ideal for applications requiring rapid rotation.
- Robust Load Capacity: With a dynamic load rating of 1349 lbf and a static load rating of 731 lbf, this bearing provides reliable support for significant radial loads in demanding environments.
- Optimized for Thermal Conditions: The C4 clearance is a critical performance feature, ensuring operational reliability by providing extra space for thermal expansion of the components, thus maintaining smooth rotation under heat.
- Premium Material Construction: All core components—rings, balls, and cage—are manufactured from Chrome Steel, ensuring high strength, durability, and resistance to wear.
6003/C4 Bearing Typical Application Areas
- Electric Motors (a primary application due to the C4 clearance)
- Industrial Gearboxes
- Pumps and Compressors
- Agricultural Machinery
- Material Handling Equipment
- General Machinery requiring a standard-size, high-performance ball bearing
