6306-2RS2/C3GJN Bearing Product Overview & Core Advantages
The 6306-2RS2/C3GJN is a metric single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Its key advantage lies in its ability to efficiently handle radial loads, making it a versatile and reliable component. The bearing features integral contact seals (2RS2) for effective contamination exclusion and is supplied pre-lubricated, ensuring immediate operational readiness and extended service life. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers consistent quality and dependable performance for general precision requirements.
6306-2RS2/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6306 | Basic bearing designation indicating a metric single row deep groove ball bearing with a 30mm bore, 72mm OD, and 19mm width. |
| 2RS2 | Bearing is fitted with low-friction NBR contact seals on both sides. The "2" indicates a specific, optimized seal design for effective protection against contaminants. |
| C3 | Specifies a greater radial internal clearance than the Normal (CN) group. This is beneficial for applications with thermal expansion or where interference fits are used. |
| GJN | Indicates the bearing is pre-lubricated with a polyurea-base grease. This grease offers good performance across the specified temperature range and contributes to the bearing's maintenance-free characteristics. |
6306-2RS2/C3GJN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing provides high strength and durability. It is rated for a dynamic load capacity of 6002 lbf and a static load capacity of 3372 lbf, ensuring reliable operation under significant radial loads.
- Effective Sealing & Contamination Resistance: The 2RS2 low-friction contact seals effectively shield the internal components from dust, moisture, and other contaminants, significantly enhancing bearing life in harsh environments.
- Optimized for Operational Stability: The C3 radial internal clearance provides operational stability in applications prone to thermal gradients or where press-fits are applied, preventing premature failure due to excessive preload.
- Maintenance-Free & Ready-to-Install: Pre-lubricated with GJN polyurea grease, the bearing is sealed for life, eliminating the need for re-lubrication and simplifying inventory and installation processes.
