51226 Bearing Product Overview & Core Advantages
The 51226 is a metric thrust ball bearing engineered for demanding applications requiring high axial load capacity. This precision bearing is designed exclusively to handle thrust loads in one direction, offering exceptional reliability and performance. Its construction from high-grade 52100 Chrome Steel ensures durability, while the stainless steel cage provides stability at operational speeds. Characterized by its high static and dynamic load ratings, the 51226 is an optimal choice for compact assemblies where space is constrained and axial force is predominant.
51226 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 51226 | Basic model number indicating a single-direction thrust ball bearing with a 130mm bore diameter. |
| Open (Seal Type) | The bearing is supplied without seals or shields, allowing for higher speed capability and requiring external lubrication and protection from contaminants. |
51226 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The bearing's geometry and use of chrome steel components enable it to support a high axial dynamic load rating of 41,850 lbf and an exceptional axial static load rating of 131,625 lbf.
- Precision Ground Washers: The housing and shaft washers are precision-ground to tight tolerances, ensuring smooth operation and accurate alignment in the assembly.
- Stainless Steel Cage: The cage, manufactured from stainless steel, offers excellent corrosion resistance and dimensional stability, contributing to reliable performance at the limiting speed.
- Robust Material Construction: Both rings and balls are made from 52100 Chrome Steel, providing high hardness and wear resistance for a long service life.
- Compliance & Safety: The bearing is compliant with ROHS and REACH regulations, making it suitable for use in environmentally conscious and regulated industries.
51226 Bearing Typical Application Areas
This thrust ball bearing is ideally suited for machinery and systems that experience significant unidirectional axial forces. Common applications include:
- Heavy-Duty Thrust Applications: Such as vertical pumps, industrial gearboxes, and crane hooks.
- Automotive Systems: Including clutch release mechanisms and steering columns.
- Power Transmission: Used in applications like worm gear reducers and screw jacks.
- General Machinery: For positioning tables, indexing heads, and other equipment requiring precise axial location.
