6204-2Z/HC5C3WT Bearing Product Overview & Core Advantages
The 6204-2Z/HC5C3WT is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while offering reliable operation. This bearing features ceramic silicon nitride (Si3N4) balls and a shielded design (2Z), making it suitable for environments requiring high-speed capability, electrical insulation, and contamination protection. Its construction ensures high reliability and long service life, ideal for precision industrial equipment.
Model Code Breakdown
| Prefix/Base Number | 6204 | Indicates a single row deep groove ball bearing with a 20mm bore, 47mm OD, and 14mm width. |
| 2Z | Shielded | The bearing is equipped with steel shields on both sides, providing effective protection against solid contaminants while allowing for high-speed operation. |
| HC5 | Hybrid Ceramic | Denotes the use of Silicon Nitride (Si3N4) ceramic balls. This provides benefits such as lower density for higher speeds, electrical insulation, and superior performance under marginal lubrication. |
| C3 | Radial Internal Clearance | Specifies a greater than normal radial internal clearance, making it suitable for applications with significant thermal expansion or where interference fits are used. |
| WT | Lubrication | Indicates the bearing is supplied without lubrication (None), allowing the end-user to apply a specialized lubricant suited for their specific operating conditions. |
6204-2Z/HC5C3WT Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and silicon nitride balls significantly reduces rotational mass and friction. This results in lower operating temperatures, higher limiting speeds (15,000 rpm), and extended service life, especially in high-speed applications.
- Robust Load Capacity: With a dynamic load rating of 2878 lbf and a static load rating of 1495 lbf, this bearing is designed to handle substantial radial loads reliably.
- Shielded Protection: The non-contact steel shields (2Z) effectively protect the bearing's interior from dust and other contaminants without significantly increasing friction, preserving its high-speed capability.
- Precision & Stability: Manufactured to ABEC 1 | ISO P0 tolerance class and featuring a C3 radial clearance, this bearing ensures consistent performance and accommodates thermal expansion in various operating environments.
6204-2Z/HC5C3WT Bearing Typical Application Areas
