6203-2Z/GJN Bearing Product Overview & Core Advantages
The 6203-2Z/GJN is a single row deep groove ball bearing designed for high reliability and robust performance in general industrial applications. This metric bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its compact design, combined with shielded construction, offers a durable and maintenance-friendly solution. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent operation and is suitable for a wide operating temperature range from -30°C to 120°C.
6203-2Z/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard series designation for a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. |
| 2Z | Indicates the bearing is shielded on both sides. This provides effective protection against contamination from solid particles while allowing for high-speed operation. |
| GJN | Specifies a standard radial internal clearance group (CN) under normal operating conditions. |
6203-2Z/GJN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built entirely from chrome steel for the rings, balls, and cage, this bearing delivers high strength and durability. It features a radial dynamic load rating of 2147 lbf and a static load rating of 1079 lbf, making it capable of handling significant radial forces in demanding applications.
- Contamination Protection & Extended Service Life: The non-contact steel shields (2Z) on both sides effectively seal the bearing, protecting the internal components from dust and debris. This design helps to maintain lubrication integrity and significantly extends the bearing's operational life without requiring frequent maintenance.
- Optimized for Standard Applications: With a limiting speed of 17,000 rpm and CN standard clearance, the 6203-2Z/GJN is engineered for stable performance across a broad range of speeds and operating temperatures.
6203-2Z/GJN Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment
- Agricultural Machinery
- Appliance Motors (e.g., washing machines, dryers)
