| Code Segment | Technical Meaning |
|---|---|
| 513/530 | Standard metric thrust ball bearing designation, indicating a bore diameter of 530 mm and an outside diameter of 800 mm. |
| Open | No integral seals or shields, allowing for custom lubrication solutions and optimal heat dissipation. |
513/530 Bearing Structural Features & Performance Benefits
Superior Load Capacity: Designed exclusively for thrust loads, this bearing boasts an axial dynamic load rating of 285,283 lbf and a remarkable axial static load rating of 1,726,083 lbf. This makes it capable of handling immense unidirectional axial forces in heavy machinery.
Precision Manufacturing: The bearing components, including rings, balls, and cage, are constructed from 52100 Chrome Steel, ensuring high hardness, wear resistance, and dimensional stability. The tight bore diameter tolerance (-0.05mm to 0) and outside diameter tolerance (-0.075mm to 0) guarantee precise fits and reliable operation.
Robust Cage Design: The chrome steel cage provides secure ball guidance and even load distribution, contributing to the bearing's stability and longevity under high thrust conditions.
Application-Specific Lubrication: As lubrication is required, the open structure allows for the use of specialized greases or oils tailored to the specific operational environment, temperature range (-30° to 110 °C), and speed requirements (limiting speed of 0.42 x 1000 rpm).
513/530 Bearing Typical Application Areas
This high-capacity thrust ball bearing is critical in applications involving significant axial forces. Key industries and machinery include:
- Heavy Industrial Machinery: Vertical pumps, large gearboxes, and industrial mixers.
- Power Generation: Hydraulic turbines and wind turbine pitch control systems.
- Construction Equipment: Large boring mills and crane slewing rings.
- Marine & Offshore: Ship propeller shafts and steering gears.
