52213 Bearing Product Overview & Core Advantages
The 52213 is a metric thrust ball bearing engineered for demanding applications requiring high axial load capacity and precision operation. This thrust bearing is designed to accommodate heavy axial loads in one direction while maintaining stable performance. Its construction from high-grade chrome steel ensures durability and long service life, making it an ideal choice for high-reliability scenarios where space constraints and load capacity are critical factors.
52213 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 52 | Indicates a thrust ball bearing series with a flat housing and shaft washers. |
| 213 | Specifies the bore diameter code (55 mm). |
| Open (Seal Type) | No seals or shields, designed for applications where external sealing is provided or where maximum speed is prioritized. |
52213 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Engineered with a robust single-direction design, this bearing delivers an axial dynamic load rating of 13,612 lbf and an axial static load rating of 33,750 lbf, making it suitable for heavy thrust applications.
- Precision Ground Components: The chrome steel rings and balls, combined with a stainless steel cage, ensure smooth operation, reduced friction, and enhanced operational accuracy.
- Optimized for Speed: The open design and precision cage contribute to a limiting speed of 2,800 rpm, enabling efficient performance in high-speed thrust scenarios.
- Stable Temperature Performance: Operates reliably within a temperature range of -30°C to 110°C, ensuring consistent performance in varied environmental conditions.
- Dimensional Precision: Features tight tolerances on the bore diameter and outside diameter for precise fit and alignment in assembly.
52213 Bearing Typical Application Areas
- Industrial Machinery: Thrust load support in heavy-duty gearboxes, vertical pumps, and crane hooks.
- Automotive Systems: Applications in clutches, steering mechanisms, and transmission systems requiring axial load management.
- Power Transmission: Used in worm gear reducers and other systems where high axial forces are present.
- General Engineering: Suitable for jacks, presses, and any machinery demanding reliable thrust bearing performance.
