6202-2ZN/C4HVE384 Bearing Product Overview & Core Advantages
The 6202-2ZN/C4HVE384 is a high-performance, single row deep groove ball bearing designed for demanding industrial applications. Engineered from chrome steel, it offers excellent durability and reliable operation. A key feature is its shielded design (2Z) on both sides, providing effective protection against contamination while retaining lubrication. This bearing is pre-set with a C4 radial internal clearance, making it suitable for applications with elevated operational temperatures or where interference fits are used, ensuring stable performance under varying thermal conditions. Its combination of high radial load capacity and moderate speed capabilities makes it a versatile and robust solution for power transmission systems.
6202-2ZN/C4HVE384 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning | Advantage |
|---|---|---|
| 6202 | Standard series designation for a single row deep groove ball bearing with a 15mm bore. | Indicates standard dimensions and interchangeability. |
| -2Z | Bearing is shielded on both sides. | Protects against contaminants, retains lubricant, and supports low-maintenance operation. |
| N | Snap ring groove on the outer ring. | Facilitates secure axial location within a housing, simplifying assembly. |
| /C4 | Radial internal clearance is greater than normal (C4 group). | Accommodates thermal expansion, ideal for applications with significant temperature gradients or tight fits. |
| HVE384 | High-Viscosity Efficiency grease, suitable for a wide temperature range. | Ensures optimal lubrication from -30°C to 120°C, contributing to long service life and reliable performance. |
6202-2ZN/C4HVE384 Bearing Structural Features & Performance Benefits
The 6202-2ZN/C4HVE384's performance is derived from its precision construction. The single row deep groove raceway geometry is optimized for high radial dynamic load rating (1812 lbf), enabling it to handle significant radial forces. The use of chrome steel for all bearing components (rings, balls, cage) ensures high hardness, wear resistance, and long-term dimensional stability. The shielded (2Z) design is a critical feature, providing a robust barrier against dust and debris without the high friction associated with contact seals, which is essential for maintaining efficiency at its limiting speed of 20,000 rpm. The pre-set C4 radial clearance is a key performance differentiator, preventing binding and reducing operational noise and heat generation in applications prone to thermal expansion. Finally, the integrated snap ring groove (N) enhances design flexibility and mounting security.
