6304-2RS2/C4S1VT405 Bearing Product Overview & Core Advantages
The 6304-2RS2/C4S1VT405 is a single row deep groove ball bearing designed for robust performance in demanding applications. Engineered to primarily handle radial loads, its compact and sealed construction ensures high reliability and long service life. A key feature is its C4 radial internal clearance, making it particularly suitable for applications involving thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a dependable balance of precision and value for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6304 | Standard series designation for a single row deep groove ball bearing with a 20mm bore. |
| 2RS2 | Indicates double lip seals on both sides, providing superior protection against contamination and moisture retention. |
| C4 | Specifies a greater than normal radial internal clearance, ideal for applications with significant temperature gradients or heavy interference fits. |
| S1 | Indicates a special heat stabilization treatment, allowing for a stable temperature range of up to 200°C. |
| VT405 | Denotes the use of a specific high-temperature, corrosion-inhibiting grease. |
6304-2RS2/C4S1VT405 Bearing Structural Features & Performance Benefits
The performance of the 6304-2RS2/C4S1VT405 is derived from its specific design features. The single row deep groove raceway is optimized for handling radial loads efficiently. The inclusion of double lip seals (2RS2) ensures excellent sealing integrity, protecting the bearing from contaminants and retaining the factory-applied VT405 lubricant, which is formulated for high-temperature operation. The C4 radial clearance is a critical feature that prevents pre-loading and potential seizure in applications subject to shaft expansion or heavy press fits. Combined with the S1 heat stabilization, this bearing maintains dimensional stability and performance across a wide operating temperature range, contributing to consistent operation and extended service intervals.
6304-2RS2/C4S1VT405 Bearing Typical Application Areas
