211SZZG Bearing Product Overview & Core Advantages
The 211SZZG is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. Engineered with shielded construction on both sides, it offers reliable protection against contaminant ingress while maintaining low operating torque. This bearing excels in handling radial loads and is manufactured to ABEC 1 | ISO P0 precision standards, ensuring consistent operation and long service life. Its chrome steel construction provides excellent durability and resistance to wear, making it a cost-effective solution for a wide range of machinery.
211SZZG Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 211 | Basic bearing series designation, indicating a standard metric deep groove ball bearing with a 55mm bore. |
| S | Indicates the use of a Chrome Steel cage, offering high strength and thermal stability. |
| ZZ | Signifies shielded construction on both sides. This provides effective sealing against large particulate contaminants. |
| G | Typically denotes a specific internal clearance group. In this case, it corresponds to the CN (Normal) radial internal clearance. |
211SZZG Bearing Structural Features & Performance Benefits
Optimized for Radial Load Capacity: The single row deep groove raceway geometry is precision-ground to efficiently support high radial dynamic loads (10881 lbf) and radial static loads (9892 lbf).
Shielded Protection: The ZZ shielded design effectively retains pre-applied lubricant and excludes larger contaminants, enhancing bearing reliability in moderately dirty environments without the added friction of contact seals.
Precision and Stability: Manufactured to ABEC 1 | ISO P0 tolerance class with tight dimensional control on the bore diameter and outside diameter, ensuring smooth running and precise shaft positioning.
Robust Material Construction: All core components—rings, balls, and cage—are made from chrome steel, providing a homogeneous material structure for consistent performance, high hardness, and excellent resistance to fatigue.
211SZZG Bearing Typical Application Areas
- Electric Motors and Generators: Ideal for supporting shafts in various AC and DC motors due to its balanced performance and shielding.
- Industrial Gearboxes and Transmissions: Used in light to medium-duty gearboxes where reliable radial load support is critical.
- Material Handling Equipment: Suitable for conveyor rollers, pulleys, and other machinery requiring durable and maintenance-friendly ball bearings.
- Agricultural Machinery: Applied in fans, pumps, and auxiliary drives that operate in challenging environments.
- General Industrial Machinery: A versatile choice for pumps, blowers, and other industrial applications demanding a standard-precision, shielded bearing solution.
