6309-2Z/C4WT Bearing Product Overview & Core Advantages
The 6309-2Z/C4WT is a single row deep groove ball bearing engineered for high-performance industrial applications. This shielded bearing excels in handling significant radial loads while also accommodating moderate axial loads in both directions. Its C4 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring stable operation under varying thermal conditions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable precision and long service life in demanding environments.
6309-2Z/C4WT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Effective contamination protection with minimal friction loss |
| C4 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits |
| WT | Wide temperature range specification | Suitable for -30°C to 120°C operating temperatures |
6309-2Z/C4WT Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The deep groove raceway geometry enables excellent radial load capacity (11,915 lbf dynamic / 7,194 lbf static) while effectively handling combined loads. The single row design provides balanced performance across various loading conditions.
Enhanced Contamination Protection: Dual steel shields (2Z) protect the bearing interior from contaminants while maintaining low operating torque and minimal heat generation, contributing to the limiting speed of 6,700 rpm.
Thermal Stability: The C4 radial clearance ensures reliable operation in applications subject to thermal expansion or where press fits are employed, preventing premature failure due to excessive preload.
Material Excellence: Constructed entirely from chrome steel for rings, balls, and cage, providing consistent hardness, wear resistance, and dimensional stability throughout the bearing assembly.
