6312-2Z/C3GWP Bearing Product Overview & Core Advantages
The 6312-2Z/C3GWP is a single row deep groove ball bearing designed for robust performance in demanding applications. This shielded bearing offers reliable operation and is characterized by its ability to accommodate high radial loads and moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent quality and interchangeability. A key feature is its C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. The combination of high dynamic load capacity and standard precision makes it a versatile and cost-effective solution for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6312 | Basic bearing series, indicating a medium width series with a 60 mm bore and 130 mm outside diameter. |
| 2Z | Shielded on both sides. This provides effective protection against contamination while minimizing friction, suitable for high-speed operation. |
| C3 | Radial internal clearance greater than normal (CN). This is ideal for applications with elevated operating temperatures or tight fits, preventing preload and ensuring smooth running. |
| GWP | Indicates the bearing is supplied without lubrication (Grease Withheld Product). This allows the user to apply a specialized lubricant tailored to the specific application requirements. |
6312-2Z/C3GWP Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 18,412 lbf, ensuring durability and long service life under heavy loads.
- Optimized for Versatile Applications: The deep groove geometry allows the bearing to handle not only significant radial loads but also axial loads from both directions, offering a compact solution for combination loads.
- Contamination Protection: The non-contact steel shields (2Z) effectively seal the bearing from dust and debris without significantly increasing friction, contributing to a high limiting speed of 5,300 rpm.
- Application-Specific Flexibility: Supplied without grease (GWP), this bearing provides the flexibility for engineers to select a high-performance lubricant that perfectly matches the operating temperature range (-30°C to 120°C) and environmental conditions.
