6215-2Z/C4GXN Bearing Product Overview & Core Advantages
The 6215-2Z/C4GXN is a single row deep groove ball bearing designed for robust performance in demanding applications. This shielded bearing excels in handling primarily radial loads while offering reliable operation. Its key advantages include a generous C4 radial internal clearance for applications involving thermal expansion, and a high limiting speed of 4,800 rpm. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution for general industrial use where precision and durability are required.
6215-2Z/C4GXN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6215 | Basic bearing series; 15mm bore code (15 x 5 = 75mm actual bore) |
| 2Z | Bearing is shielded on both sides, providing effective protection against contaminants while allowing high-speed operation. |
| C4 | Specifies a greater than normal radial internal clearance, suitable for applications with significant temperature variations or where interference fits are used. |
| GXN | Indicates the bearing is supplied without lubrication, allowing for application-specific grease selection. |
6215-2Z/C4GXN Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing ensures high strength and wear resistance, contributing to a long service life under radial dynamic loads up to 15,152 lbf.
Contaminant Protection: The double-shielded (2Z) design effectively excludes particulates while minimizing friction, enabling a high limiting speed and reducing maintenance needs in dirty environments.
Thermal Stability: The C4 radial clearance accommodates differential thermal expansion between the shaft and housing, preventing preload and potential seizure in applications with operating temperatures up to 120°C.
Flexible Lubrication: Supplied without grease, it offers the flexibility to use specialized lubricants optimized for specific speed, temperature, or environmental conditions.
