307-2Z Bearing Product Overview & Core Advantages
The 307-2Z is a single row deep groove ball bearing featuring integral shielded protection. Engineered for radial load applications, this metric bearing delivers reliable performance in compact spaces with its 35mm bore and 80mm outside diameter. Its nylon cage construction contributes to smooth operation at high speeds (up to 7,600 rpm), while the pre-applied grease lubrication and shielded design provide maintenance-free operation across a wide temperature range (-30° to 120°C). Manufactured to P0 tolerance class with standard CN clearance, this bearing offers consistent performance for general industrial applications requiring dependable radial load capacity.
307-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 307 | Basic bearing designation (35mm bore, 80mm OD, 21mm width) | Standard dimensions for compatibility and interchangeability |
| 2Z | Double-sided steel shields | Effective contamination protection while maintaining high-speed capability |
307-2Z Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway profile enables excellent radial load capacity (7,801 lbf dynamic / 5,957 lbf static) while accommodating moderate axial loads in both directions.
Nylon Cage Construction: The lightweight nylon cage reduces centrifugal forces, enabling higher rotational speeds while providing quiet operation and reduced friction.
Integrated Shielding System: The double-sided steel shields (2Z) effectively retain lubricant and exclude contaminants, ensuring long-term reliability without maintenance requirements.
Precision Manufacturing: Manufactured to P0 tolerance class with chrome steel rings and balls, delivering consistent dimensional accuracy and reliable performance in demanding applications.
307-2Z Bearing Typical Application Areas
- Electric Motors: Main and auxiliary motor applications requiring reliable radial support
- Industrial Gearboxes: Power transmission systems needing compact bearing solutions
