6203-2Z/C3 GJN Bearing Product Overview & Core Advantages
The 6203-2Z/C3 GJN is a metric single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Its key advantages stem from its shielded design (2Z) and increased internal radial clearance (C3). This configuration offers effective protection against contaminant ingress while accommodating thermal expansion, making it a reliable choice for applications requiring high operational reliability and stability under varying thermal conditions. Its compact design and high load capacity provide an excellent solution for radial loads in electric motors, gearboxes, and general machinery.
Model Code Breakdown
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6203 | Basic Bearing Series & Size | Standard deep groove ball bearing with 17mm bore, 40mm OD. |
| 2Z | Shields on Both Sides | Provides effective protection against contaminants, enhancing bearing life in dirty environments. |
| C3 | Increased Radial Internal Clearance | Accommodates thermal expansion, preventing seizure in high-temperature or high-speed applications. |
| GJN | Lubrication Designation (None) | Allows for application-specific lubrication, offering flexibility for specialized operational needs. |
6203-2Z/C3 GJN Bearing Structural Features & Performance Benefits
The performance of the 6203-2Z/C3 GJN is defined by its specific construction:
- Robust Construction & High Load Capacity: Manufactured from chrome steel for both rings, balls, and cage, this bearing ensures high strength and durability. With a dynamic load rating of 2147 lbf and a static load rating of 1079 lbf, it is engineered to handle significant radial loads reliably.
- Optimized for Thermal Stability: The C3 radial internal clearance is a critical feature that allows for dimensional changes due to thermal expansion during operation, preventing preload and potential bearing failure. This makes it suitable for applications with fluctuating temperatures.
- Contaminant Protection: The non-contact steel shields (2Z) on both sides effectively keep out dust and debris while minimizing friction, contributing to a long service life and reduced maintenance needs.
- Precision & Speed: Built to ABEC 1 | ISO P0 tolerance class, it offers reliable performance for general industrial use. The limiting speed of 17,000 rpm is supported by the low-friction deep groove raceway and stable cage design.
6203-2Z/C3 GJN Bearing Typical Application Areas
The 6203-2Z/C3 GJN is a versatile component found in numerous sectors, including:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery requiring robust, shielded bearings
