6003-Z/C4 Bearing Product Overview & Core Advantages
The 6003-Z/C4 is a single row deep groove ball bearing designed for reliable performance in general industrial applications. This metric bearing excels at handling primarily radial loads and offers a compact design with a 17 mm bore diameter. Its key advantages include robust construction from chrome steel and a shielded design on one side to protect against contamination, ensuring long service life and consistent operation.
6003-Z/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6003 | Standard designation for a single row deep groove ball bearing with 17mm bore, 35mm OD, and 10mm width. |
| -Z | Indicates a shielded (non-contact) seal on one side, protecting the bearing interior from dust and debris while minimizing friction. |
| /C4 | Specifies a greater than normal radial internal clearance, suitable for applications with significant thermal expansion or where interference fits are used. |
6003-Z/C4 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The single row deep groove construction and chrome steel components provide a radial dynamic load rating of 1349 lbf and a radial static load rating of 731 lbf, ensuring reliable performance under demanding conditions.
- Optimized Internal Clearance: The C4 radial clearance accommodates thermal expansion in high-speed or high-temperature environments, preventing premature failure due to excessive preload.
- Contamination Protection: The shielded (Z) design effectively prevents the ingress of solid contaminants, extending bearing life and reducing maintenance needs in harsh environments.
- High-Speed Capability: With a limiting speed of 21,000 rpm, this bearing is suitable for a wide range of high-speed applications, supported by its precision ABEC 1 | ISO P0 tolerance class.
6003-Z/C4 Bearing Typical Application Areas
This versatile bearing is commonly used in:
- Electric Motors and Small Power Tools
- Pumps and Gearboxes
- Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
