312MG Bearing Product Overview & Core Advantages
The 312MG metric ball bearing is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in standard industrial applications. Manufactured with precision ABEC 1 (ISO P0) tolerances, it offers a cost-effective solution without compromising on fundamental bearing integrity. Its open design allows for versatile lubrication options, while the standard CN radial internal clearance ensures stable operation across a wide temperature range from -30°C to 120°C. This bearing is engineered for durability and consistent performance in demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 312 | Standard bearing series designation, indicating specific bearing dimensions (60mm bore, 130mm OD, 31mm width). |
| MG | Indicates the use of a Chrome Steel cage, offering good strength and corrosion resistance. |
| (No Seal Suffix) | Open seal type, meaning the bearing is supplied without seals or shields, allowing for high-speed operation and custom lubrication. |
| (No Lubrication Suffix) | Lubrication: None, providing flexibility for the user to apply the most suitable grease or oil for the specific application. |
312MG Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove construction is optimized to handle significant radial dynamic load ratings of 20,525 lbf and radial static load ratings of 17,535 lbf, making it suitable for applications with substantial radial forces.
- Robust Material Construction: All core components, including the rings, balls, and cage, are manufactured from Chrome Steel, ensuring high hardness, wear resistance, and long service life.
- Precision Performance: Built to ABEC 1 (ISO P0) tolerance class, this bearing provides reliable running accuracy and smooth operation, minimizing vibration and noise.
- Versatile Operating Range: The standard CN radial internal clearance and wide temperature range make it adaptable to various operational conditions and thermal expansions.
- High-Speed Capability: The open design and robust Chrome Steel cage contribute to a high limiting speed of 6,000 rpm, enabling use in demanding rotational applications.
