6308-2Z/C3LHT55 Bearing Product Overview & Core Advantages
The 6308-2Z/C3 is a single row deep groove ball bearing designed for reliable performance in demanding industrial applications. This metric bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its shielded design (2Z) provides effective contamination protection, and the C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used. Manufactured from high-grade chrome steel and built to ABEC 1 | ISO P0 tolerance standards, it offers a robust balance of precision, durability, and cost-effectiveness for a wide range of machinery.
6308-2Z/C3LHT55 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| 6308 | Basic bearing series and size designation | Indicates a medium-duty, single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width. |
| -2Z | Bearing with shields on both sides | Provides effective protection against solid contaminants while allowing for higher limiting speeds compared to contact seals. Offers a good balance of protection and performance. |
| /C3 | Radial internal clearance greater than normal (C3 group) | Compensates for thermal expansion in the shaft or housing, making it ideal for applications with high operational temperatures or tight interference fits, preventing premature failure. |
6308-2Z/C3LHT55 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing ensures high strength, wear resistance, and a long operational lifespan under consistent radial loads.
- Optimized Contamination Protection: The non-contact steel shields (2Z) on both sides effectively retain the factory-applied grease and protect the internal raceways from larger particulate contaminants, enhancing reliability in dirty environments.
- Thermal & Fit Adaptability: The C3 radial internal clearance is a critical feature that accommodates dimensional changes due to thermal expansion during operation and allows for secure press fits, reducing the risk of binding and overheating.
- Balanced Performance: With a limiting speed of 7,500 rpm and a dynamic load rating of 915 lbf, it provides a versatile solution for a broad spectrum of medium-duty, medium-speed applications.
