51468 Bearing Product Overview & Core Advantages
The 51468 metric thrust ball bearing is engineered for heavy-duty axial load applications requiring exceptional reliability. This thrust bearing features a robust chrome steel construction, delivering a high axial static load rating of 1,791,278 lbf and a substantial axial dynamic load rating of 345,307 lbf. Its open design allows for versatile lubrication options, making it suitable for industrial environments demanding precise axial positioning and high load capacity in a single direction.

51468 Bearing Structural Features & Performance Benefits
High Load Capacity Design: The bearing's large bore diameter of 340 mm and outside diameter of 620 mm, combined with its substantial width of 220 mm, create a large contact area that distributes thrust loads efficiently, preventing premature failure under extreme conditions.
Precision Manufacturing: Tight dimensional tolerances on the bore (-0.04mm to 0) and outside diameter (-0.05mm to 0) ensure precise fit and alignment, critical for maintaining system accuracy and preventing uneven load distribution.
Durable Material Construction: All critical components—including rings, balls, and cage—are manufactured from 52100 Chrome Steel, providing excellent hardness, wear resistance, and fatigue life for long-term reliability in demanding applications.
Optimized for Heavy Thrust: Specifically designed to accommodate unidirectional axial loads, making it ideal for applications where substantial thrust forces are the primary concern, rather than combined loads.
51468 Bearing Typical Application Areas
- Heavy Industrial Machinery: Vertical pumps, large gearboxes, and industrial mixers requiring substantial axial support
- Power Generation Equipment: Hydraulic turbines and large generator thrust positions
- Marine & Offshore Systems: Propulsion systems, stern tube bearings, and deck machinery
- Mining & Construction Equipment: Large drilling rigs, crane slewing mechanisms, and heavy-duty presses
- Steel Mill Equipment: Rolling mill stands and continuous casting machinery
