6309-2Z/C3LHT30 Bearing Product Overview & Core Advantages
The 6309-2Z/C3LHT30 is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This shielded bearing excels at handling high radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a robust construction for high rigidity, a generous C3 radial internal clearance suitable for applications with thermal expansion, and integrated shields (2Z) that protect against contamination. Pre-lubricated with high-temperature grease (LHT30), it offers reliable operation across a wide temperature range, making it a versatile and durable choice for high-reliability machinery.
Model Code Breakdown
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Provides effective contamination protection while minimizing friction and heat generation compared to contact seals. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in shafts and housings, ideal for applications with high operating temperatures or where fits cause clearance reduction. |
| LHT30 | High-temperature lithium complex soap grease | Enables reliable performance within the specified temperature range (-30°C to 120°C), offering long-term lubrication stability. |
6309-2Z/C3LHT30 Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and high-grade chrome steel construction (rings, balls, and cage) provide excellent load capacity and operational durability, supporting a high dynamic load rating of 11915 lbf.
- Optimized for Thermal Conditions: The C3 internal clearance is a critical feature that prevents bearing preload and potential seizure in applications subject to significant temperature fluctuations or interference fits.
- Shielded & Pre-Lubricated for Longevity: The 2Z shields retain grease and exclude larger contaminants, while the LHT30 grease ensures consistent lubrication from the outset. This combination supports a limiting speed of 6700 rpm and contributes to a maintenance-free service life in many environments.
- Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing guarantees consistent running accuracy and smooth operation for general industrial applications.
6309-2Z/C3LHT30 Bearing Typical Application Areas
The 6309-2Z/C3LHT30 is ideally suited for a wide range of industrial machinery requiring robust and reliable performance. Common applications include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
