308-Z Bearing Product Overview & Core Advantages
The 308-Z is a single row deep groove ball bearing designed for exceptional performance in radial load applications. Engineered with precision chrome steel components and a nylon cage, this bearing delivers reliable operation and long service life. Its shielded design provides effective contamination protection while maintaining low friction, making it ideal for applications requiring consistent performance and high limiting speeds up to 8,500 rpm. The 308-Z represents an optimal balance of durability, precision, and value for industrial applications.
Model Code Breakdown
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 308 | Standard bore diameter 40mm, outside diameter 90mm, width 23mm | Standard dimensions for easy replacement and integration |
| Z | Single shielded on one side | Protects against contaminants while allowing high-speed operation |
308-Z Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables excellent radial load capacity (10,274 lbf dynamic / 8,093 lbf static) while accommodating moderate axial loads in both directions.
Nylon Cage Construction: The lightweight nylon cage provides superior guidance, reduced friction, and excellent performance at high speeds, contributing to the bearing's 8,500 rpm limiting speed.
Shielded Protection: The single-sided steel shield retains factory-applied grease while excluding contaminants, extending lubrication life and reducing maintenance requirements.
Precision Manufacturing: Manufactured to P0 tolerance class with CN radial clearance, ensuring consistent performance and reliable operation in various applications.
