6309-2RS1/C3LHT55 Bearing Product Overview & Core Advantages
The 6309-2RS1/C3LHT55 is a sealed deep groove ball bearing engineered for robust performance in demanding industrial applications. This single row bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include a generous C3 radial internal clearance for thermal expansion management in high-temperature environments, and integrated contact seals (2RS1) that effectively protect against contaminants while retaining lubrication. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable, consistent performance for a wide range of machinery.
6309-2RS1/C3LHT55 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6309 | Standard Bearing Series & Size | Denotes a metric series bearing with a 45mm bore, 100mm OD, and 25mm width. |
| 2RS1 | Contact Seals on Both Sides | Provides superior protection against dust, moisture, and other contaminants, making the bearing maintenance-free in many applications. |
| C3 | Radial Internal Clearance | Greater than normal clearance, suitable for applications with thermal expansion or where interference fits are used. |
| LHT55 | High-Temperature Grease | Indicates the bearing is pre-lubricated with a grease suitable for the specified temperature range (-30°C to 120°C). |
6309-2RS1/C3LHT55 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing offers excellent durability and a high dynamic load rating of 11,915 lbf, ensuring long service life under significant radial loads.
- Effective Sealing Solution: The 2RS1 contact seals on both sides provide a reliable barrier, protecting the bearing's interior from contamination. This design is crucial for applications in dirty or humid environments, reducing the risk of premature failure.
- Optimized for Thermal Conditions: The C3 radial internal clearance allows for differential thermal expansion between the inner and outer rings, preventing operational issues and maintaining smooth rotation in applications where operating temperatures fluctuate.
- Ready-to-Install & Low Maintenance: Pre-lubricated with LHT55 grease and sealed for life, this bearing is a maintenance-free solution, reducing downtime and total cost of ownership.
