51126 Bearing Product Overview & Core Advantages
The 51126 metric thrust ball bearing is engineered for high-capacity axial load applications requiring precision and reliability. This open-type thrust bearing is designed exclusively to accommodate unidirectional thrust loads, making it ideal for scenarios where heavy axial forces are predominant. Manufactured from 52100 Chrome Steel for both rings and balls, and featuring a stainless steel cage, it delivers excellent durability and corrosion resistance. Its compact design and high axial dynamic load rating of 26,775 lbf ensure robust performance in demanding industrial environments.
51126 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 51126 | Basic model number for a metric thrust ball bearing with a 130mm bore and 170mm OD. |
| Open (Seal Type) | No seals or shields, allowing for higher speed capability and easier re-lubrication, but requiring a cleaner operating environment. |
51126 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The bearing's design is optimized to handle significant unidirectional thrust loads, with a high axial static load rating of 99,000 lbf, providing exceptional stability under heavy axial forces.
- Precision Ground Components: Manufactured with tight dimensional tolerances (e.g., bore diameter tolerance: -0.025mm to 0), ensuring precise fit and reliable operation in high-precision assemblies.
- Durable Material Construction: The use of 52100 Chrome Steel for rings and balls, combined with a stainless steel cage, offers superior wear resistance and longevity, even in challenging conditions.
- Optimized for Speed: The open design and robust cage contribute to a limiting speed of 2,600 rpm, suitable for various medium-speed applications.
- Compliance & Safety: Meets ROHS and REACH standards, ensuring environmental compliance and safety for use in regulated industries.
51126 Bearing Typical Application Areas
This thrust ball bearing is widely used in machinery and equipment where substantial axial loads are the primary concern. Key applications include:
- Industrial Gearboxes: For positioning and supporting axial shafts.
- Heavy-Duty Automotive Systems: Such as clutch release mechanisms and steering columns.
- Construction and Mining Equipment: In applications like crane hooks and heavy-duty jacks.
- Machine Tool Spindles: Where precise axial location is critical.
- Pumps and Compressors: For handling thrust loads in rotating assemblies.
