308SZZC Bearing Product Overview & Core Advantages
The 308SZZC is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and smooth operation. Featuring shielded construction on both sides, it offers effective contamination protection while maintaining low friction. Manufactured to ABEC 1 | ISO P0 tolerance standards with CN radial internal clearance, this bearing delivers consistent precision and durability in demanding industrial environments. Its optimized geometry and chrome steel construction ensure excellent performance across a wide temperature range from -30° to 120°C.
308SZZC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 308 | Basic bearing designation indicating 40mm bore, 90mm OD, 23mm width | Standard dimensional compatibility |
| S | Single shield on one side | Partial contamination protection |
| ZZ | Shielded on both sides | Enhanced contamination exclusion |
| C | Enhanced radial internal clearance (CN) | Optimal fit for various operating conditions |
308SZZC 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.
Shielded Protection: Dual steel shields provide effective contamination protection without significantly increasing rotational friction, maintaining high limiting speed capabilities up to 8,500 rpm.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance standards with chrome steel construction throughout (rings, balls, cage) ensures consistent performance and long service life.
Thermal Stability: Designed to operate reliably across a broad temperature range from -30° to 120°C, making it suitable for various industrial environments.
