6309-RS1Z/C3GJN Bearing Product Overview & Core Advantages
The 6309-RS1Z/C3GJN is a single row deep groove ball bearing engineered for high performance and reliability in demanding applications. This metric bearing is distinguished by its asymmetric sealing configuration, featuring one side shielded and one side sealed, offering a balanced solution for contamination protection. Designed primarily for radial loads, it delivers robust performance with a radial dynamic load rating of 11915 lbf and a limiting speed of 6700 rpm. Manufactured to ABEC 1 | ISO P0 tolerance standards and featuring a C3 radial internal clearance, it is an excellent choice for applications requiring dependable operation under standard precision and moderate speed conditions.
6309-RS1Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| RS1 | One side contact seal (typically NBR rubber) | Provides superior protection against contaminants like dust and moisture from one side. |
| Z | One side shielded (metal) | Offers low-friction protection from larger particles, ideal for the opposite side of the seal. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, making it suitable for applications with expected temperature variations. |
| GJN | Grease filling, polyurea thickener, temperature range -30°C to +150°C | Provides ready-to-use, long-term lubrication with excellent high-temperature stability and oxidation resistance. |
6309-RS1Z/C3GJN Bearing Structural Features & Performance Benefits
Asymmetric Sealing for Optimal Protection: The combination of a contact seal (RS1) on one side and a non-contact shield (Z) on the other provides an effective barrier against contaminants while managing friction and heat generation. This design is ideal for environments where one side is exposed to higher contamination risk.
Robust Load Capacity: With a dynamic load rating of 11915 lbf and a static load rating of 7194 lbf, this bearing is built to handle significant radial loads, ensuring long service life in demanding conditions.
Enhanced Operational Stability with C3 Clearance: The C3 radial internal clearance is larger than standard, allowing for differential thermal expansion between the inner and outer rings. This prevents pre-loading and potential seizure in applications with fluctuating operational temperatures.
Pre-lubricated for Maintenance-Free Operation: The bearing is pre-filled with GJN grease, a high-quality polyurea-based lubricant. This ensures immediate operation and reduces maintenance needs, offering reliable performance across its specified temperature range of -30°C to 120°C.
