212S Bearing Product Overview & Core Advantages
The 212S metric ball bearing is a single row deep groove ball bearing designed for exceptional performance in radial load applications. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable operation and consistent quality. Its open design allows for versatile lubrication options, while the chrome steel construction of all components ensures durability and a long service life. This bearing is ideal for applications requiring a robust and cost-effective solution for handling significant radial dynamic loads up to 12,612 lbf.
212S Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 212S | Basic bearing designation indicating a metric, single row deep groove ball bearing with specific dimensions (60mm bore, 110mm OD). |
| Open (Seal Type) | No integral seals or shields. This allows for high-speed operation and custom lubrication schemes but requires a clean operating environment or external sealing. |
| CN (Clearance) | Specifies Normal radial internal clearance as per ISO standards, suitable for most common operating conditions. |
212S Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High Load Capacity: The optimized deep groove geometry enables the bearing to efficiently support high radial dynamic and static loads, making it a workhorse in demanding applications.
- Precision & Reliability: Built to ABEC 1 | ISO P0 tolerance class, this bearing ensures smooth and quiet running, minimizing vibration and contributing to the overall precision of the assembly.
- High-Speed Capability: The open design and chrome steel cage contribute to a high limiting speed of 6,700 rpm, accommodating applications that require rapid rotation.
- Robust Material Construction: All critical components—rings, balls, and cage—are made from chrome steel, providing excellent hardness, wear resistance, and a long operational lifespan.
212S Bearing Typical Application Areas
The 212S bearing is widely used across various industries due to its robust design and reliable performance. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring a standard-duty, high-quality radial bearing.
