513/850 Bearing Product Overview & Core Advantages
The 513/850 is a heavy-duty thrust ball bearing engineered for applications requiring exceptional axial load capacity. This metric system bearing features an open design, allowing for high-performance lubrication systems. Its primary function is to accommodate unidirectional thrust loads with remarkable reliability. Manufactured from 52100 Chrome Steel, it offers superior strength and durability, making it ideal for the most demanding industrial environments where high axial static and dynamic load ratings are paramount.
513/850 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 513 | Indicates the bearing series, specifying a thrust ball bearing design. |
| /850 | Specifies the bore diameter of 850 mm. |
| Open (Seal Type) | No integral seals, designed for use with external lubrication systems for optimal heat dissipation and performance in controlled environments. |
513/850 Bearing Structural Features & Performance Benefits
- Exceptional Load Capacity: Engineered to handle immense axial dynamic load ratings of 601,364 lbf and axial static load ratings of 4,578,234 lbf, providing robust support for heavy thrust applications.
- Precision Dimensions: Features tight dimensional tolerances on the bore diameter (850 mm), outside diameter (1250 mm), and width (315 mm) for precise fit and alignment in machinery.
- Durable Construction: All components, including rings, balls, and cage, are manufactured from 52100 Chrome Steel, ensuring high wear resistance and long service life.
- Optimized for Controlled Environments: The open seal type allows for efficient lubrication management, which is critical for heat dissipation in low-speed, high-load scenarios. The specified limiting speed is 0.25 x 1000 rpm.
