511/530 F Bearing Product Overview & Core Advantages
The 511/530 F is a metric thrust ball bearing engineered for demanding applications requiring exceptional axial load capacity. This open-type bearing is designed to accommodate heavy thrust loads in a single direction, making it a robust solution for high-stress environments. Its construction from high-grade 52100 Chrome Steel ensures superior durability and wear resistance. The bearing's precision-ground components and generous load ratings provide reliable performance and long service life in heavy-duty machinery.
511/530 F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 511 | Designates a thrust ball bearing with a flat seating surface (housing washer). |
| 530 | Indicates the bore diameter of 530 mm. |
| F | Signifies a carbon steel cage (in this context, the provided specification indicates a Stainless Steel cage for enhanced corrosion resistance). |
511/530 F Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Engineered with a large contact angle and robust construction to handle substantial axial dynamic load ratings of 146,250 lbf and impressive axial static load ratings of 990,000 lbf.
- Precision Ground Components: The housing washer (ID: 534 mm) and shaft washer (OD: 636 mm) are precision-ground to ensure optimal alignment and load distribution, minimizing stress concentrations.
- Durable Material Construction: Rings and balls made from 52100 Chrome Steel provide high hardness and fatigue resistance. The stainless steel cage offers excellent strength and corrosion resistance, contributing to bearing stability at the limiting speed.
- Stable Operation: The open design allows for efficient lubrication management, supporting stable operation within a temperature range of -30°C to 110°C.
511/530 F Bearing Typical Application Areas
This heavy-duty thrust ball bearing is ideally suited for applications involving high unidirectional axial loads and moderate speeds, including:
- Vertical Pumps and Compressors
- Heavy-Duty Industrial Gearboxes
- Crane Hooks and Slewing Rings
- Large Presses and Extrusion Machinery
- Mining and Construction Equipment
