6203-Z Bearing Product Overview & Core Advantages
The 6203-Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with metric dimensions and manufactured to P6 tolerance class, this bearing delivers high precision and reliable operation. Its key advantage lies in its ability to efficiently handle radial loads, making it an ideal choice for compact assemblies requiring smooth rotation and long service life. The integral Z-type shield provides effective contamination protection, preserving the bearing's performance and contributing to its maintenance-friendly characteristics.
6203-Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Basic bearing designation, indicating a medium series deep groove ball bearing with a 17mm bore diameter. |
| -Z | Signifies a non-contact shield on one side. This provides protection against large particulate contaminants while minimizing friction and heat generation. |
6203-Z Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and high-quality chrome steel construction enable efficient handling of the specified radial dynamic load rating of 2237 lbf and radial static load rating of 1068 lbf.
- High-Speed Capability: The combination of a low-friction stainless steel cage and precision P6 tolerances allows for a high limiting speed of 24,000 rpm, suitable for demanding rotational applications.
- Controlled Internal Clearance: The standard CN radial internal clearance ensures optimal performance under normal operating conditions and temperatures.
- Pre-Lubricated & Shielded: The bearing is pre-lubricated with grease and features a shield, offering protection from contaminants and providing ready-to-install, low-maintenance operation within a temperature range of -30°C to 120°C.
