6309-2RS1/C3LHT23 Bearing Product Overview & Core Advantages
The 6309-2RS1/C3LHT23 is a single row deep groove ball bearing designed for robust performance in demanding applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering reliable operation across a wide temperature range. This sealed bearing features a generous C3 radial internal clearance, making it exceptionally suitable for applications involving thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution for general industrial use where high precision is not the primary concern but dependable performance is essential.
6309-2RS1/C3LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| -2RS1 | Contact seals on both sides | Provides superior protection against contaminants and retains lubricant effectively. |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, ideal for applications with interference fits or elevated operating temperatures. |
| LHT23 | High-temperature lithium soap thickened grease | Enables reliable operation within the specified temperature range of -30°C to 120°C. |
6309-2RS1/C3LHT23 Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its robust construction. The single row deep groove raceway is optimized for radial load capacity, with a dynamic load rating of 11915 lbf and a static load rating of 7194 lbf. The contact seals (2RS1) are a critical feature, shielding the precision-ground chrome steel components from dust, moisture, and other contaminants, thereby significantly extending service life. The C3 internal clearance provides operational stability in environments prone to thermal fluctuations. The integrated LHT23 grease lubrication ensures immediate readiness for service and consistent performance across its entire operating temperature range, contributing to its limiting speed of 6,700 rpm.
6309-2RS1/C3LHT23 Bearing Typical Application Areas
This versatile bearing is commonly specified in a wide array of industrial machinery due to its sealed and pre-lubricated design. Typical applications include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Agricultural Machinery (e.g., conveyors, rollers)
- Material Handling Equipment
- Pumps and Compressors
