6312-2Z/C3WT Bearing Product Overview & Core Advantages
The 6312-2Z/C3 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This shielded bearing offers excellent radial load capacity and moderate axial loads in both directions. Its key advantages include robust construction with chrome steel components, a generous C3 radial internal clearance suitable for applications with thermal expansion, and integrated shields (2Z) that protect against contamination while allowing for high limiting speeds. This combination makes it an ideal, cost-effective solution for general industrial machinery requiring dependable operation.
6312-2Z/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6312 | Basic bearing series; defines dimensions: 60mm bore, 130mm OD, 31mm width. | Standardized bearing dimensions for easy interchangeability. |
| -2Z | Bearing is equipped with shields on both sides. | Provides effective contamination protection, retaining pre-lubrication and extending service life. |
| /C3 | Specifies a radial internal clearance greater than normal (C3 group). | Accommodates thermal expansion in the housing or shaft, preventing preload and potential seizure. |
6312-2Z/C3WT Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and continuous shoulder design enable the bearing to handle significant radial loads as well as axial loads from both directions, making it highly versatile.
- Shielded Protection: The non-contact steel shields (2Z) effectively seal the bearing against dust and other particulates without significantly increasing friction, contributing to the high limiting speed of 5,300 rpm.
- Optimized Internal Clearance: The C3 clearance is a critical feature for applications where operational temperatures cause differential expansion between the bearing rings and adjacent components, ensuring stable performance and preventing thermal locking.
- High-Quality Material: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing ensures high strength, durability, and consistent performance under load.
6312-2Z/C3WT Bearing Typical Application Areas
The 6312-2Z/C3 is widely used across various industrial sectors due to its balanced performance and protective features. Common applications include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
