52211 Bearing Product Overview & Core Advantages
The 52211 is a metric thrust ball bearing engineered for applications requiring high axial load capacity and precision. Designed exclusively to accommodate thrust loads in a single direction, it features a robust construction with hardened chrome steel rings and balls, ensuring reliable performance in demanding environments. Its compact design and high axial static load rating of 30,150 lbf make it an ideal choice for high-rigidity, space-constrained assemblies where precise axial positioning is critical.
52211 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 5 | Indicates a thrust ball bearing type. |
| 2 | Designates the bearing series, relating to cross-sectional dimensions and load capacity. |
| 211 | Specifies the bore diameter of 45 mm (calculated from bore code 11 * 5 = 55mm, standard adjustment applies for this series). |
| (No suffix) | Indicates an open (unsealed) design, suitable for environments where external sealing is provided or where regular re-lubrication is planned. |
52211 Bearing Structural Features & Performance Benefits
- High Axial Rigidity and Load Capacity: The single-direction thrust design, combined with hardened chrome steel components, provides exceptional resistance to axial dynamic (13,162 lbf) and static loads, ensuring stable operation under heavy thrust forces.
- Precision Ground Components: Tight dimensional tolerances on the bore diameter and outside diameter guarantee precise shaft and housing fits, critical for maintaining alignment and reducing vibration.
- Corrosion-Resistant Cage: The stainless steel cage offers superior corrosion resistance and durability, contributing to consistent performance and extended service life, even in challenging conditions.
- Optimized for Moderate Speeds: With a limiting speed of 3,000 rpm, the bearing is suitable for a wide range of industrial applications requiring dependable thrust support.
52211 Bearing Typical Application Areas
- Industrial Machinery: Thrust support in heavy-duty gearboxes, industrial pumps, and vertical shaft systems.
- Automotive Systems: Components in clutches, transmissions, and steering mechanisms requiring precise axial load management.
- Material Handling Equipment: Used in crane hooks, lifting screws, and other machinery where high thrust loads are prevalent.
- General Engineering: Any application demanding robust, single-direction thrust load capacity with high rigidity and precision.
