6311-2Z/C3WT Bearing Product Overview & Core Advantages
The 6311-2Z/C3 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This shielded bearing offers reliable operation and long service life, featuring a C3 radial internal clearance suitable for applications with thermal expansion or interference fits. Its robust construction from chrome steel ensures high durability and consistent performance under significant radial dynamic loads up to 16,096 lbf. The integrated shields protect against contamination, making it a versatile and maintenance-friendly solution for various industrial settings.
6311-2Z/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6311 | Basic bearing designation indicating a medium series, single row deep groove ball bearing with a 55mm bore. |
| 2Z | Signifies non-contact shields on both sides, providing effective protection against contaminants while minimizing friction. |
| C3 | Indicates a greater than normal radial internal clearance, ideal for applications with shaft expansion or where elevated operating temperatures are expected. |
6311-2Z/C3WT Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway geometry is engineered to handle high radial dynamic loads efficiently, while also accommodating moderate axial loads in both directions.
- Shielded Protection: The 2Z non-contact shields effectively seal the bearing interior from dust and debris without significantly increasing friction, contributing to a high limiting speed of 5,600 rpm.
- Precision & Stability: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures consistent running accuracy and smooth operation, which is critical for reducing vibration and noise.
- Thermal Adaptation: The C3 internal clearance provides operational stability in environments with thermal fluctuations, preventing preload and potential bearing seizure.
