511/1180 F Bearing Product Overview & Core Advantages
The 511/1180 F thrust ball bearing is a metric single-direction thrust bearing engineered for applications requiring high axial load capacity in one direction. Its robust design, featuring large bore and outside diameters, makes it suitable for supporting substantial axial static load ratings up to 4,500,000 lbf. Manufactured from high-grade 52100 Chrome Steel for rings and balls, it ensures durability and reliable performance in demanding industrial environments. The open seal type allows for easy re-lubrication and is ideal for applications where heat dissipation is a priority.
511/1180 F Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation |
|---|---|
| 511 | Basic model designation for a single-direction thrust ball bearing. |
| /1180 | Specifies the massive bore diameter of 1180 mm. |
| F | Indicates a machined brass or steel cage. In this specification, it corresponds to the stainless steel cage for enhanced corrosion resistance. |
511/1180 F Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The bearing's design is optimized to handle extremely high axial static loads (4,500,000 lbf) and dynamic loads, making it a cornerstone for heavy-duty thrust applications.
- Robust Construction: Components made from 52100 Chrome Steel provide high hardness and wear resistance, ensuring a long operational lifespan under strenuous conditions.
- Stainless Steel Cage: The "F" cage offers excellent strength and corrosion resistance, contributing to the bearing's stability and reliability at the specified limiting speed.
- Precision Tolerances: Strict dimensional tolerances on the bore, outside diameter, and width guarantee precise fitment and optimal performance in the assembly.
- Compliance & Safety: The bearing is ROHS and REACH compliant, meeting international standards for environmental safety and material restrictions.
