51130 M Bearing Product Overview & Core Advantages
The 51130 M is a metric thrust ball bearing engineered for demanding applications requiring high axial load capacity and precision. This open-type bearing is designed to accommodate thrust loads in a single direction, offering a compact and robust solution. Manufactured from 52100 Chrome Steel for both rings and balls, it ensures excellent durability and wear resistance. Its high axial static load rating of 99,000 lbf makes it ideal for high-stress environments where reliability is paramount.
51130 M Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 51130 | Basic Model Number | Defines the bearing's core dimensions: 150mm bore, 190mm OD, 31mm width. |
| M | Brass Cage | Indicates a brass cage (stamped or machined), offering good strength and guidance for the balls, suitable for a range of operating conditions. |
| (No Seal Suffix) | Open Design | The open seal type allows for easy re-lubrication and is suitable for clean environments or where specific lubrication regimes are applied. |
51130 M Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The single-direction thrust ball bearing design is optimized to carry substantial axial loads, with a high static load rating for applications with heavy, steady forces.
- Precision Ground Components: The bearing features tight dimensional tolerances on the bore diameter and outside diameter, ensuring precise fit and reliable performance in precision assemblies.
- Robust Material Construction: The use of 52100 Chrome Steel for rings and balls provides high hardness and resistance to fatigue, while the stainless steel cage offers corrosion resistance and dimensional stability.
- Wide Temperature Range: An operational temperature range from -30°C to 110°C provides versatility for various industrial environments.
- Compliant Standards: The bearing is ROHS and REACH compliant, meeting stringent environmental and safety regulations.
51130 M Bearing Typical Application Areas
The 51130 M is suited for machinery and systems requiring robust thrust support. Common applications include:
- Industrial Gearboxes and thrust positions
- Heavy-Duty Machine Tools for axial load support
- Automotive Steering Systems (e.g., thrust assemblies)
- Construction and Agricultural Machinery
- Pumps and Compressors for handling axial forces
