6309-2Z/C3WT Bearing Product Overview & Core Advantages
The 6309-2Z/C3WT is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This metric bearing features shielded protection (2Z) on both sides and is manufactured with a C3 radial internal clearance, making it ideally suited for applications with thermal expansion or where interference fits are used. Its robust construction from chrome steel provides high durability and reliable operation, capable of handling significant radial loads with a dynamic rating of 11915 lbf. The combination of shielded design, precision ABEC 1 | ISO P0 tolerance, and optimized internal geometry ensures long service life and stable operation across a wide temperature range.
Model Code In-Depth Analysis
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 2Z | Steel shields on both sides | Provides effective contamination protection while maintaining low friction and allowing higher speeds compared to contact seals |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in shafts and housings, ideal for applications with temperature variations or interference fits |
| WT | No lubrication (without grease) | Allows for custom lubrication selection based on specific application requirements and operating conditions |
6309-2Z/C3WT Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables the bearing to handle not only radial loads but also moderate axial loads in both directions, providing versatile load capacity in a compact design.
Shielded Protection: The non-contact steel shields (2Z) effectively prevent the ingress of contaminants while minimizing friction, contributing to the bearing's limiting speed of 6,700 rpm and extended service life.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class with consistent dimensional accuracy, ensuring reliable performance and easy installation in various applications.
C3 Internal Clearance: The increased radial internal clearance provides operational stability in applications subject to thermal expansion, preventing premature failure due to excessive preload.
Chrome Steel Construction: All critical components including rings, balls, and cage are manufactured from high-quality chrome steel, providing excellent wear resistance and durability under demanding conditions.
