6204-2ZTN9/C3/R806 Bearing Product Overview & Core Advantages
The 6204-2ZTN9/C3 is a single row deep groove ball bearing engineered for reliable performance in demanding applications. This shielded bearing is designed to primarily handle radial loads while also accommodating moderate axial loads in both directions. Its compact design, combined with a C3 radial internal clearance and a high-performance Nylon cage (TN9), makes it an excellent choice for applications requiring robust operation, moderate speeds, and long service life without relubrication. The ABEC 1 (ISO P0) tolerance class ensures consistent quality and performance for general industrial use.
6204-2ZTN9/C3/R806 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 2Z | Non-contact shields on both sides | Provides effective protection against contaminant ingress while minimizing friction and heat generation. |
| TN9 | Nylon (Polyamide) cage, glass fiber reinforced | Lightweight design contributes to higher limiting speeds, reduced vibration, and excellent acceleration characteristics. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with elevated operating temperatures or heavy loads, preventing premature failure. |
6204-2ZTN9/C3/R806 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from Chrome Steel for both rings and balls, this bearing offers a high dynamic load rating of 2878 lbf and a static load rating of 1495 lbf, ensuring durability under significant radial loads.
- Optimized for Speed: The lightweight TN9 Nylon cage allows for a limiting speed of 15,000 rpm, making it suitable for a wide range of high-speed applications without sacrificing stability.
- Maintenance-Free Operation: The combination of non-contact shields (2Z) and a pre-greased design (if lubricated variant is selected) creates a sealed, lubricated environment, protecting against contamination and extending service intervals.
- Thermal Stability: The specified C3 clearance provides operational reliability across a temperature range of -30°C to 120°C, accommodating differential expansion between the shaft and housing.
