6204-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6204-2Z/C3GJN is a single row deep groove ball bearing designed for high reliability and robust performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering a compact design. The combination of shielded construction and a C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where a tighter fit is required, ensuring consistent operation and long service life.
6204-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6204 | Standard series designation for a single row deep groove ball bearing with a 20mm bore. |
| 2Z | Indicates bearings are shielded on both sides. This provides effective protection against contaminant ingress while minimizing friction, contributing to the bearing's limiting speed. |
| C3 | Specifies a greater than normal radial internal clearance. This is essential for applications where thermal expansion is a factor or for press-fit mounting conditions. |
| GJN | Signifies that the bearing is supplied without lubrication ("None"). This allows the user to apply a specialized lubricant tailored to their specific operational environment. |
6204-2Z/C3GJN Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway geometry is engineered to support significant radial dynamic and static load ratings (2878 lbf and 1495 lbf respectively), ensuring durability under load.
Shielded Protection: The non-contact steel shields (2Z) effectively seal the bearing, protecting the chrome steel balls and raceways from dust and other contaminants, thereby enhancing operational reliability and lifespan.
Controlled Internal Clearance: The C3 clearance provides operational stability in applications prone to thermal expansion or where interference fits are used, preventing premature failure due to excessive preload.
High-Speed Capability: The precision chrome steel cage and optimized design contribute to a high limiting speed of 15,000 rpm, making it a capable high-speed bearing for various machinery.
