6202-2RSH/C4HT Bearing Product Overview & Core Advantages
The 6202-2RSH/C4HT is a single row deep groove ball bearing designed for high-performance applications requiring reliability and precision. This sealed bearing excels in handling significant radial loads and moderate axial loads in both directions. Its key advantages include a generous C4 radial internal clearance for thermal expansion management in demanding thermal environments, high-quality chrome steel construction for durability, and integrated seals for contaminant exclusion. Engineered to the ABEC 1 | ISO P0 tolerance class, it offers a robust balance of precision and value for a wide range of industrial uses.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6202 | Standard series designation for a single row deep groove ball bearing with a 15mm bore. | Defines the basic dimensions and type. |
| 2RS | Contact seals on both sides. | Provides superior protection against contaminants and retains lubricant. |
| H | Enhanced dimensional stability and performance due to heat stabilization. | Allows for stable operation at temperatures up to 120°C. |
| C4 | Greater than normal radial internal clearance. | Prevents preload and accommodates shaft expansion in high-temperature applications. |
| HT | High-temperature grease. | Enables reliable lubrication within the specified -30° to 120°C temperature range. |
6202-2RSH/C4HT Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from high-grade chrome steel for the rings, balls, and cage, this bearing ensures high strength, wear resistance, and a long operational life under substantial radial dynamic load ratings of 1812 lbf.
Effective Sealing: The 2RS contact seals on both sides are a critical feature, providing an effective barrier against dust, moisture, and other contaminants. This makes the bearing suitable for harsh environments and contributes to its maintenance-free characteristic by retaining the factory-applied high-temperature grease.
Optimized Internal Clearance: The C4 radial internal clearance is a key performance differentiator. It is specifically selected for applications where differential thermal expansion between the shaft and housing occurs, preventing dangerous bearing preload and ensuring smooth, reliable operation.
High-Temperature Capability: The combination of the H heat stabilization suffix and HT high-temperature grease allows this bearing to perform reliably across a wide temperature range from -30°C to 120°C, making it a versatile choice for various industrial settings.
