6308-2Z/C3LHT23 Bearing Product Overview & Core Advantages
The 6308-2Z/C3LHT23 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while offering reliable operation. The bearing features integral shielded seals for contaminant protection and is manufactured to ABEC 1 | ISO P0 precision class, ensuring consistent quality and smooth operation. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, providing robust and reliable service.
6308-2Z/C3LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2Z | Steel shields on both sides | Provides effective protection against solid contaminants while allowing for high-speed operation with minimal friction. |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in the shaft or housing, preventing preload and ensuring stable performance in varying temperature conditions. |
| LHT23 | High-temperature grease lubrication | Enables reliable operation within a wide temperature range of -30°C to 120°C, reducing maintenance needs. |
6308-2Z/C3LHT23 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from high-grade chrome steel for both rings, balls, and cage, this bearing offers excellent durability and resistance to wear, contributing to a long service life.
- Optimized Load Capacity: The single row deep groove raceway design is optimized to carry significant radial dynamic and static load ratings (915 lbf and 5395 lbf respectively), making it a reliable choice for various mechanical systems.
- High-Speed Capability: The combination of a precision-ground raceway and a chrome steel cage allows for a high limiting speed of 7,500 rpm, suitable for a wide range of industrial applications.
- Sealed & Pre-lubricated Design: The 2Z shields protect the internal components from dust and debris, while the factory-applied LHT23 grease provides long-term, maintenance-free operation under normal conditions.
