6307-2Z Bearing Product Overview & Core Advantages
The 6307-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric precision bearing features integral shielded seals for contamination protection and is pre-lubricated with grease for long service life. Engineered with a P6 tolerance class and standard CN radial internal clearance, it delivers high running accuracy and reliable operation. Its core advantages include robust radial load capacity, suitability for high-speed operation up to 9,500 rpm, and a versatile temperature range from -30°C to 120°C, making it an ideal choice for applications requiring reliability and precision.
6307-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6307 | Basic Bearing Number | Defines the core dimensions: 35 mm bore, 80 mm OD, 21 mm width. |
| -2Z | Seal Type | Specifies shielded seals on both sides. This provides effective protection against contaminants while offering low friction for high-speed applications. |
6307-2Z Bearing Structural Features & Performance Benefits
- Optimized Raceway Geometry & High-Grade Materials: The deep groove raceways and components made from Chrome Steel are heat-treated for high hardness and durability, enabling high dynamic and static load ratings (7891 lbf / 4271 lbf).
- Effective Sealing & Lubrication: The 2Z non-contact shields retain the factory-fill grease and exclude larger particulate contaminants. This combination provides a maintenance-free solution for the bearing's operational life in many applications.
- Precision & Stability: Manufactured to P6 tolerance class, this bearing ensures precise running dimensions and reduced vibration, contributing to smoother operation and extended service life of the entire assembly.
- High-Speed Capability: The combination of the stainless steel cage, optimized internal geometry, and effective lubrication allows for a high limiting speed of 9,500 rpm.
