212 Bearing Product Overview & Core Advantages
The 212 metric ball bearing is a single row deep groove ball bearing engineered for outstanding performance in radial load applications. Constructed from high-grade chrome steel, it delivers exceptional durability and operational reliability. Its open design facilitates easy re-lubrication and allows for high limiting speeds, making it a versatile and robust solution for a wide array of industrial machinery. This bearing is characterized by its high precision P0 tolerance class and standard CN radial internal clearance, ensuring consistent performance and long service life.
212 Bearing Model Code Explained, Specifications & Naming Convention
| Model Element | Technical Meaning |
|---|---|
| 212 | Standard metric series designation, indicating the bearing dimensions: 60mm bore, 110mm OD, 22mm width. |
| Seal Type: Open | No integral seals or shields. This allows for the highest possible speed and facilitates custom lubrication schemes. |
| Tolerance Class: P0 | Standard industrial tolerance, ensuring reliable performance for general applications. |
| Clearance: CN | Normal radial internal clearance, suitable for most operating conditions. |
212 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open design and nylon cage significantly reduce friction and heat generation, enabling a high limiting speed of 6,700 rpm. This makes it ideal for applications requiring rapid rotation.
- Robust Load Capacity: Engineered with a deep groove raceway, this single row bearing efficiently handles significant radial dynamic loads (12,612 lbf) and moderate axial loads in both directions.
- Precision and Stability: Manufactured to P0 tolerance class with tight dimensional control on the bore diameter, outside diameter, and width, ensuring smooth operation and precise shaft positioning.
- Durable Construction: Components made from chrome steel offer high hardness and resistance to wear, while the lightweight nylon cage provides excellent strength and low friction.
212 Bearing Typical Application Areas
The 212 deep groove ball bearing is a fundamental component across numerous industries due to its versatility and reliability. Key applications include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
