51360 Bearing Product Overview & Core Advantages
The 51360 is a metric thrust ball bearing engineered for applications demanding exceptional axial load capacity and robust construction. This bearing is specifically designed to accommodate thrust loads in a single direction, making it an ideal solution for heavy-duty machinery where high axial forces are prevalent. Manufactured from high-grade 52100 Chrome Steel, it offers superior durability and reliable performance in demanding operational environments. Its open design requires lubrication, providing flexibility for specific application needs.
51360 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 51360 | Basic model number for a metric thrust ball bearing. |
| Open (Seal Type) | The bearing has no integral seals or shields, allowing for higher speed capability and custom lubrication solutions. It requires external sealing in contaminated environments. |
51360 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The bearing's geometry and use of 52100 Chrome Steel for both rings and balls enable it to support very high axial dynamic load ratings of 193,336 lbf and exceptional axial static load ratings of 887,995 lbf.
- Robust Construction: The Chrome Steel cage ensures ball guidance and structural integrity under high-stress conditions, contributing to the bearing's overall reliability.
- Precision Tolerances: Strict dimensional tolerances on the bore diameter (300 mm), outside diameter (480 mm), and width (140 mm) ensure precise fitment and stable operation within assemblies.
- Material Compliance: The bearing is manufactured from ROHS and REACH compliant materials, making it suitable for use in regulated industries with environmental and safety standards.
51360 Bearing Typical Application Areas
This thrust ball bearing is designed for heavy machinery and equipment subjected to significant axial forces. Common applications include:
- Heavy-Duty Industrial Gearboxes
- Vertical Pumps and Compressors
- Crane Hooks and Slewing Rings
- Large Presses and Extrusion Machinery
- Mining and Construction Equipment
