6303-2RSH/GJN Bearing Product Overview & Core Advantages
The 6303-2RSH/GJN is a single row deep groove ball bearing designed for reliable performance in demanding applications. This sealed bearing excels at handling primarily radial loads and offers robust operation within a wide temperature range. Its key advantages include a compact design, high operational reliability, and long service life due to its integral seals and high-quality chrome steel construction, making it an excellent choice for general industrial machinery where contamination protection is essential.
6303-2RSH/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| 2RS | Contact seals on both sides | Provides excellent protection against contamination and retains lubricant effectively. |
| H | Hardened cage | Increases mechanical strength and durability of the cage. |
| GJN | Grease filling, polyurea thickener, temperature range -30°C to +150°C | Offers a ready-to-install, long-lasting lubrication solution suitable for a broad operating temperature. |
6303-2RSH/GJN Bearing Structural Features & Performance Benefits
Robust Sealed Design: The double-contact seals (2RS) are a critical structural feature, providing a high degree of protection against dust, moisture, and other contaminants. This significantly extends the bearing's service life and reduces maintenance needs, making it suitable for dirty or wet environments.
High Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing achieves a high radial dynamic load rating of 3057 lbf and a radial static load rating of 1495 lbf. This ensures reliable performance under significant radial stresses.
Optimized for Reliability: The hardened steel cage (H suffix) ensures stable ball guidance and high mechanical strength, contributing to smooth operation. The bearing comes pre-lubricated with a high-quality polyurea grease (GJN), which is effective across the specified temperature range of -30°C to 120°C, ensuring immediate readiness for operation and long-term lubrication.
Precision & Standardization: Manufactured to ABEC 1 | ISO P0 tolerance class and standard CN radial internal clearance, this bearing offers consistent, high-quality performance for a wide array of industrial applications.
