6203-2Z/C3GWP Bearing Product Overview & Core Advantages
The 6203-2Z/C3GWP is a metric single row deep groove ball bearing engineered for robust performance in demanding industrial applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering operational reliability. The bearing features integrated shields (2Z) for contaminant protection and is supplied with a high-quality grease pre-lubrication (GWP), making it a ready-to-install, low-maintenance solution. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent performance and is suitable for a wide operating temperature range.
6203-2Z/C3GWP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6203 | Standard designation for a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. | Defines the core bearing dimensions and type. |
| 2Z | Bearing is equipped with shields on both sides. | Provides effective protection against solid contaminants, enhancing bearing life and reliability. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Ideal for applications with expected thermal expansion or where interference fits are used, preventing preload and overheating. |
| GWP | Indicates the bearing is pre-lubricated with grease. | Ensures immediate operation, reduces maintenance needs, and offers long-term lubrication. |
6203-2Z/C3GWP Bearing Structural Features & Performance Benefits
Deep Groove Raceway & Robust Construction: The deep, continuous raceways on both rings are optimized for handling significant radial loads. Manufactured from high-grade chrome steel, the bearing components offer excellent durability and wear resistance.
Shielded Design for Contamination Resistance: The 2Z shields are firmly attached to the outer ring, creating an effective barrier against dust and debris without significant contact friction. This design contributes to the bearing's suitability for a wide range of industrial environments without a major sacrifice in limiting speed.
Optimized Internal Clearance: The C3 clearance is a critical feature for applications involving thermal gradients or press-fits. It accommodates dimensional changes, preventing excessive preload that can lead to premature failure, thus ensuring stable operation and extended service life.
Pre-Lubrication for Immediate Service: Filled with a high-performance grease (GWP), the bearing is protected from the start against wear and corrosion. This makes it a maintenance-free component for the majority of its service life, ideal for sealed-for-life applications.
6203-2Z/C3GWP Bearing Typical Application Areas
- Electric Motors: A standard choice for small to medium-sized motors requiring reliable, long-life radial support.
- Industrial Gearboxes and Power Transmission Systems: Used in various stages for supporting shafts under radial loads.
- Agricultural Machinery: Suitable for components like idler pulleys and conveyor rollers in demanding, dusty environments.
- Material Handling Equipment: Found in fans, blowers, and conveyor systems where contamination resistance is key.
- General Industrial Machinery: A versatile component in pumps, compressors, and other machinery requiring a robust and common ball bearing size.
