6304-2Z/C3GWP Bearing Product Overview & Core Advantages
The 6304-2Z/C3GWP is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This shielded bearing features a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Its primary advantages include robust construction for handling radial loads efficiently, extended service life due to high-grade chrome steel components, and ready-to-install convenience with factory-fitted shields and corrosion-resistant GW lubrication. This combination makes it an ideal, cost-effective solution for general industrial machinery requiring dependable performance.
6304-2Z/C3GWP Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| -2Z | Non-contact steel shields on both sides | Provides effective contamination protection while maintaining high-speed capability and low friction. |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, prevents preload in tight fits, and is ideal for vibrating machinery. |
| GWP | Lubricated with a rust-inhibitive grease | Offers immediate corrosion resistance and initial lubrication, suitable for storage and operation in mildly humid environments. |
6304-2Z/C3GWP Bearing Structural Features & Performance Benefits
- Robust Deep Groove Design: The optimized raceway geometry enables the bearing to handle significant radial dynamic loads (3574 lbf) and moderate axial loads in both directions, providing versatile load-carrying capacity.
- Shielded Protection: The ZZ shields retain lubrication and effectively exclude larger contaminants, enhancing the bearing's operational life without the torque increase associated with contact seals.
- C3 Internal Clearance: This feature is critical for applications involving thermal gradients or heavy press fits, as it prevents excessive preloading and potential bearing seizure.
- High-Grade Material: Manufactured from chrome steel for rings, balls, and cage, ensuring high strength, durability, and consistent performance under the specified temperature range (-30° to 120 °C).
