6306-2Z/C3HT Bearing Product Overview & Core Advantages
The 6306-2Z/C3 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This shielded bearing offers excellent radial load capacity and moderate axial load handling in both directions. Its key advantages include robust construction with chrome steel components, a generous C3 radial internal clearance for thermal expansion in high-speed or high-temperature environments, and integrated shields that protect against contamination while maintaining high limiting speeds. This combination makes it an ideal, cost-effective solution for applications requiring durability and consistent operation.
6306-2Z/C3HT Bearing Model Code Explained, Specifications & Naming Convention
| Model Suffix | Technical Meaning | Advantage |
|---|---|---|
| 2Z | Shielded on both sides | Provides effective protection against dust and debris, enhancing bearing life in contaminated environments. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion from high speeds or temperature differentials, preventing premature failure due to preload. |
6306-2Z/C3HT Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and chrome steel construction (rings, balls, and cage) provide high radial dynamic load rating (6002 lbf) and reliable operation under substantial loads.
- Optimized for Speed and Temperature: The C3 internal clearance is a critical feature that allows the bearing to operate effectively at its high limiting speed (9,600 rpm) and across a wide temperature range (-30°C to 120°C), preventing binding and reducing friction.
- Contamination Resistance: The non-contact shields (2Z) on both sides help retain the factory-applied lubrication and exclude larger particulate contaminants, contributing to a long, maintenance-free service life in many applications.
- Precision and Consistency: Manufactured to ABEC 1 | ISO P0 tolerance class, ensuring reliable dimensional accuracy and smooth running for general industrial use.
