6215-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6215-2Z/C3GJN is a single row deep groove ball bearing designed for robust performance in demanding applications. As a shielded bearing with C3 radial internal clearance, it excels at handling primarily radial loads while offering reliable operation. Its key advantages include a compact design for space-constrained installations, high operational reliability due to its shielded construction, and suitability for applications requiring controlled internal clearance. Manufactured from high-grade chrome steel, it ensures durability and consistent performance, making it an excellent choice for general industrial machinery where precision and longevity are critical.
6215-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 6215 | Basic bearing series and size designation (75mm bore, 130mm OD) | Standardized dimensions for easy interchangeability. |
| 2Z | Bearing is equipped with shielded seals on both sides | Provides effective protection against contaminants while allowing high-speed operation. |
| C3 | Specifies a greater than normal radial internal clearance | Ideal for applications with thermal expansion or where interference fits are used. |
| GJN | Indicates the bearing is supplied without lubrication | Allows the user to apply a specific lubricant tailored to their application needs. |
6215-2Z/C3GJN Bearing Structural Features & Performance Benefits
- Shielded Design (2Z): The non-contact steel shields on both sides effectively prevent the ingress of solid contaminants, enhancing bearing life and reliability in dirty environments without significantly increasing friction.
- Optimized Internal Clearance (C3): The C3 radial internal clearance is larger than standard, making this bearing particularly suitable for applications where thermal expansion of the shaft or housing is expected, or where tight interference fits are used, preventing preload and potential seizure.
- High-Grade Material: Constructed entirely from chrome steel (rings, balls, and cage), this bearing offers high strength, wear resistance, and a long operational lifespan under dynamic and static loads.
- Performance Ratings: With a radial dynamic load rating of 15,152 lbf and a limiting speed of 4,800 rpm, it delivers robust performance for a wide range of industrial applications.
