6304-2RS HN/C3 GJN Bearing Product Overview & Core Advantages
The 6304-2RS is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its core strength lies in its ability to efficiently handle radial loads while offering robust performance due to its sealed construction. Featuring a C3 radial internal clearance, this bearing is optimized for applications where thermal expansion is a factor, ensuring stable operation across a wide temperature range. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution for general industrial use where precision and consistent performance are paramount.
6304-2RS HN/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6304 | Basic Bearing Number | Denotes a metric, single row deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width. |
| -2RS | Seal Type | Specifies that the bearing is equipped with Rubber Seals (RS) on both sides. This provides effective protection against contamination and retains lubricant, enhancing service life. |
| C3 | Radial Internal Clearance | Indicates a greater than normal radial internal clearance. This is beneficial in applications with high operational temperatures or where fits result in a reduction of internal clearance. |
6304-2RS HN/C3 GJN Bearing Structural Features & Performance Benefits
The performance of the 6304-2RS bearing is a direct result of its thoughtful engineering. The single row deep groove raceway geometry is fundamental for handling high radial load capacity. The inclusion of Nitrile Rubber (NBR) Seals (2RS) on both sides is a critical feature, creating a robust barrier against dust, moisture, and other contaminants. This sealed design makes the bearing inherently maintenance-free for its entire service life, as it is pre-lubricated at the factory. The specified C3 clearance provides operational stability in environments prone to thermal expansion, preventing premature failure due to excessive preload. Manufactured entirely from Chrome Steel, including the balls and cage, it ensures high strength, durability, and consistent performance under the specified temperature range of -30°C to 120°C.
