6308-2Z/C3W64H Bearing Product Overview & Core Advantages
The 6308-2Z/C3W64H is a single row deep groove ball bearing engineered for robust performance in demanding applications. Its core advantages stem from a combination of shielded design and Solid Oil lubrication, offering reliable operation with minimal maintenance. This bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions, making it a versatile and durable component. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring consistent performance under varying operational conditions.
6308-2Z/C3W64H Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6308 | Standard designation for a metric single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width. | Defines the core bearing dimensions and type. |
| 2Z | Bearing is equipped with shields on both sides. | Provides effective protection against contamination from solid particles, enhancing bearing life. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Accommodates thermal expansion in the shaft or housing, ideal for applications with high operating temperatures or tight fits. |
| W64H | Indicates the bearing is pre-lubricated with Solid Oil. | Offers a maintenance-free solution, eliminates lubricant leakage, and provides reliable performance in a wide temperature range from -30°C to 120°C. |
6308-2Z/C3W64H Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway geometry is precision-engineered to support high radial dynamic load ratings (915 lbf) and radial static load ratings (5395 lbf), ensuring reliable performance under significant stress.
Contamination Resistance & Longevity: The non-contact 2Z shields on both sides act as a robust barrier against dust and debris, protecting the internal components and significantly extending the service life of the bearing in harsh environments.
Maintenance-Free Operation: The integration of Solid Oil (W64H) replaces traditional grease, creating a sealed lubrication system. This prevents oil leakage, eliminates the need for re-lubrication, and ensures consistent performance, making it ideal for hard-to-reach or sealed-for-life applications.
Thermal Stability & Fit Tolerance: The specified C3 clearance provides operational stability in applications prone to thermal growth, preventing premature failure due to excessive preload. Combined with the ABEC 1 | ISO P0 tolerance class, it delivers reliable and precise operation for a wide range of industrial uses.
