6308-Z Bearing Product Overview & Core Advantages
The 6308-Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered to primarily handle radial loads, its robust construction ensures high reliability and long service life. A key feature is the inclusion of a shielded design on one side, offering effective protection against contaminants while retaining lubrication. Manufactured to a P6 tolerance class, this precision bearing provides superior running accuracy, making it an ideal choice for applications requiring smooth operation and consistent performance.
6308-Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6308 | Basic Bearing Number | Denotes a metric, single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width. |
| -Z | Suffix for Shield | Indicates a non-contact steel shield fitted on one side of the bearing. This protects against large particulate contaminants and helps retain the pre-applied grease lubrication. |
6308-Z Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The deep groove raceway and robust chrome steel construction enable high radial dynamic load rating (9509 lbf) and static load rating (5395 lbf), providing dependable support in various mechanical systems.
- Optimized for Speed & Precision: The combination of a stainless steel cage, precision P6 tolerance, and standard CN radial internal clearance allows for a high limiting speed of 11,000 rpm, ensuring stable performance in high-speed applications.
- Enhanced Service Life & Low Maintenance: The single-sided shield protects the internal components, extending bearing life by preventing contamination. The bearing is pre-lubricated with grease, facilitating simplified installation and promoting a long, maintenance-free operational period.
- Broad Operating Range: With a temperature range from -30°C to 120°C, this bearing is suitable for use in diverse environmental conditions.
