51202 Bearing Product Overview & Core Advantages
The 51202 metric thrust ball bearing is engineered for applications requiring precise axial load handling in a compact design. As a dedicated thrust bearing, it efficiently accommodates high axial dynamic loads while maintaining smooth operation. Its construction from 52100 Chrome Steel ensures durability and reliable performance in demanding environments, making it an ideal choice for high-precision machinery where space and load capacity are critical factors.
51202 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 51 | Indicates a thrust ball bearing series. |
| 2 | Specifies the width series of the bearing. |
| 02 | Denotes a bore diameter of 15 mm (commonly, 02 corresponds to 15mm in many metric series). |
| (No Suffix) | The absence of additional suffixes indicates a standard, open (unsealed) design with standard tolerances and no pre-lubrication specified in the model code. |
51202 Bearing Structural Features & Performance Benefits
Optimized for Pure Thrust Loads: The bearing's design is specifically intended to handle axial loads exclusively, with a high axial static load rating of 5625 lbf and a axial dynamic load rating of 3578 lbf, ensuring reliable performance under significant force.
High-Precision Components: The use of 52100 Chrome Steel for both rings and balls provides excellent wear resistance and dimensional stability. The stainless steel cage offers superior corrosion resistance and maintains ball alignment at the specified limiting speed of 10,000 rpm.
Compact and Lightweight: With a bearing width of only 12 mm and a total weight of 0.046 kg, it is an ideal solution for applications with strict space and weight constraints.
Strict Dimensional Tolerances: The tight bore diameter tolerance and outside diameter tolerance ensure precise fits on shafts and in housings, contributing to overall system accuracy and reduced vibration.
51202 Bearing Typical Application Areas
The 51202 thrust ball bearing is commonly specified in a variety of industrial and precision applications, including:
- Automotive Systems: Thrust applications in transmissions and steering mechanisms.
- Industrial Machinery: Used in machine tool tables, indexing heads, and other equipment requiring precise axial positioning.
- Pumps and Compressors: To accommodate axial forces generated by impellers and rotors.
- Precision Instruments and Medical Devices: Where compact size, reliability, and the ability to handle pure axial loads are paramount.
