514 Series
сверхтяжёлые Упорные шарикоподшипники
25–360mm Bore | Однонаправленная | Maximum Cross-Section | P5/P4/P0 Grade
The 514 series is the heaviest однонаправленный thrust шарикоподшипник type — featuring the maximum поперечное сечение for the highest осевая нагрузка capacity in the thrust шарикоподшипник family. Создано для extreme thrust applications: large вертикально-расточный станокs, гидротурбина thrust pads, marine propeller вал поддерживает, and structural bridge bearings.
Максимальная осевая грузоподъёмность — для экстремальных упорных применений
Luoyang Songju 514 series extra-heavy thrust шарикоподшипники represent the ultimate in осевая нагрузка capacity within the thrust шарикоподшипник family. The massive поперечное сечение — with washer thicknesses and ball diameters far exceeding 511/512/513 series — позволяет the 514 series to handle the most extreme осевая нагрузкаs encountered in industrial and civil engineering applications.
Each 514 bearing is a precision-engineered assembly of thick, сквозной закалки сталь GCr15 washers with a heavy комплект шариков in a robust pressed steel or machined brass cage. The flat корпусная шайба design поддерживает simple, reliable geometry — there are no rolling elements to skid, no complex geometries to fail. Pure осевая нагрузка, pure reliability.
Стандартный диапазон внутренних диаметров covers 25mm to 360mm. Обработанный латунный сепараторs (M suffix) are standard for sizes above 51410 — providing the robust ball guidance required for the large ball diameters and high contact forces characteristic of this series. For двунаправленная extreme loads, contact engineering for двунаправленный special configurations.

Почему выбирают Luoyang Songju 514 Series
The ultimate thrust шарикоподшипник — maximum поперечное сечение for the highest осевая нагрузка capacity in the series family
Maximum Cross-Section
The largest washers and ball diameters in the thrust шарикоподшипник family. 51420 (100mm bore) weighs 13.4 kg — over 10× the mass of an equivalent-bore 51120 bearing. Every gram of steel contributes to осевая нагрузка capacity measured in hundreds of kilonewtons.
Extreme Load Survival
Static load ratings exceeding 865 kN (51420) — enough to support a loaded semi-truck on a single bearing. Dynamic ratings engineered for decades of continuous operation under loads that would destroy lighter-серии in hours.
Through-Hardened Heavy Rings
Extra-thick washer sections ensure uniform through-hardness and consistent load distribution across the full комплект шариков. The additional ring mass acts as a heat sink, dissipating frictional heat in непрерывный applications.
Machined Brass Cage Standard
Models 51410 and above ship with обработанные латунные сепараторы в стандартной комплектации equipment. The superior strength and thermal stability of brass cages are essential for reliably guiding the large-diameter balls under the extreme contact forces of heavy-load operation.
Смазка Access
The open design обеспечивает excellent lubricant access and heat dissipation. Oil bath lubrication is standard for large 514 bearings; circulating oil systems рекомендуются для continuous high-load, высокоскоростной applications to manage operational temperatures.
Взаимозаменяемость с SKF/NTN/NSK
Прямая размерная замена для SKF 514, NTN 514, NSK 514, and FAG 514 series. Одинаковые монтажные размеры, same extreme load ratings — конкурентные цены and engineering support from Luoyang for the most demanding thrust applications.
Отрасли и применения for 514 Series
Доверяют в прецизионных отраслях по всему миру для надежной осевой опоры
Hydroelectric Turbine Thrust Pads
Kaplan and Francis turbine упорные подшипники support the entire rotating assembly weight plus hydraulic thrust — часто превышающее 1,000 kN in large installations. 514 серии are specified for their proven reliability in multi-decade continuous operation.
Marine Propeller Shafts
Ship propeller thrust кареткаs transmit the propeller's forward (or astern) thrust to the vessel hull. 514 bearings handle ударная нагрузкаing from wave action and ice impact while maintaining reliable thrust transmission in the harsh marine environment.
Large Vertical Boring Mills
The worktable упорный подшипник in вертикально-расточный станокs and vertical turning lathes. 514 bearings support the combined weight of the workpiece (часто превышающее 100 tons) and cutting forces while maintaining precise axial positioning for machining accuracy.
Structural & Bridge Bearings
Civil engineering applications — bridge expansion bearings, building isolation bearings, and structural support points. 514 bearings accommodate thermal expansion and contraction of bridge decks while reliably transmitting vertical structural loads to piers and abutments.
