Thrust Ball
Bearings
511 / 512 / 513 / 514 / 532 / 533 Series | 10–500mm Bore | Single & Double Direction
Purpose-designed for pure осевая нагрузка applications. Separable three-piece construction — вальцевая шайба, корпусная шайба, and шариково-сепараторная сборка — позволяет independent mounting of each component. Доступно с flat or spherical back-face washers for static misalignment compensation. Trusted in machine tool spindles, поворотный столs, vertical вал arrangements, крюк кранаs, and ход screw support.
Упорные шарикоподшипники for Осевая нагрузка Применения
Luoyang Songju thrust шарикоподшипники are manufactured in six dimensional series — 511, 512, 513, 514, 532, and 533 — engineered for applications where the primary load is axial (thrust). Each bearing is manufactured from high-carbon chromium подшипниковая сталь GCr15 (100Cr6 / 52100) in our производственный объект с сертификатом ISO 9001:2015.
Разъёмная three-piece design — consisting of a вальцевая шайба, корпусная шайба, and шариково-сепараторная сборка — allows each component to be mounted independently for simplified installation. This is especially valuable in applications where the вал and корпус are difficult to access simultaneously, or where the washers must be mounted with посадка с натягомs.
The 532 and 533 series incorporate spherical корпусная шайбаs and aligning seat washers, enabling the bearing to compensate for static угловое смещение between the вал and корпус — a critical feature in applications where perfect perpendicularity cannot be guaranteed or where structural deflection occurs under load.
Single vs. Double Direction
Thrust шарикоподшипники are available in two fundamental configurations. Single-direction bearings (511–514, 532–533) accept осевая нагрузка in one direction only and are the most common type for general industrial applications. Double-direction bearings (522–524, 542–544) incorporate two rows of balls and can accommodate осевая нагрузкаs from both directions — ideal for reversing thrust applications, двунаправленная ход screws, and vertical spindles subject to both upward and downward forces.

542 / 543 / 544
Six Series for Every Осевая нагрузка Requirement
From compact light-series 511 to тяжёлый 514 — select the right thrust шарикоподшипник for your application requirements
511 Series
Single-direction, flat back-face. The most compact and economical thrust шарикоподшипник series. Идеально для light to moderate осевая нагрузкаs in vertical вал поддерживает, steering columns, and general industrial machinery.
512 Series
Single-direction, flat back-face with larger поперечное сечение than 511. Handles significantly higher осевая нагрузкаs for the same размер отверстия. Widely used in machine tool spindle thrust кареткаs and rotary indexing tables.
513 Series
Single-direction, flat back-face with heavy поперечное сечение. Предназначено для high осевая нагрузкаs in demanding industrial applications — крюк кранаs, тяжёлый вертикальный насосs, экструдер thrust кареткаs, and кузнечный пресс screws.
514 Series
Single-direction, flat back-face with maximum поперечное сечение for the highest осевая нагрузка capacity. Создано для extreme thrust applications — large вертикально-расточный станокs, гидротурбина thrust pads, and marine propeller вал поддерживает.
532 Series
Single-direction with spherical корпусная шайба and aligning seat. Compensates for static угловое смещение between вал and корпус. лёгкие-to-medium поперечное сечение for applications where mounting precision cannot be guaranteed.
533 Series
Single-direction with spherical корпусная шайба and heavy поперечное сечение. Combines high осевая нагрузка capacity with self-alignment capability — ideal for тяжёлый applications with potential misalignment such as large крюк кранаs and строительный подшипникs.

Where Упорные шарикоподшипники Excel
Any application where the primary load is axial — from precision machine tool spindles to heavy industrial lifting equipment
Machine Tool Spindles
Vertical milling spindles, drilling spindles, and boring mill quills where the spindle weight and cutting thrust create pure осевая нагрузкаing. 512 series widely specified for preloaded thrust кареткаs in CNC vertical обрабатывающий центрs.
Rotary Indexing Tables
Support the table weight and clamping thrust in CNC поворотный столs and precision indexing mechanisms. Double-direction 522 series used where upward workpiece ejection forces must also be supported.
Lead Screw Support
Provide axial location for ход screws and ball screws in machine tool feed axes. Compact 511 серии at the screw end поглощает thrust while allowing the screw to rotate freely. Идеально для manual and powered machine slides.
Crane Hooks & Hoists
Heavy-series 513 and 514 упорные подшипники in крюк крана assemblies, supporting the full lifted load. Spherical 533 series preferred where hook swivel alignment cannot be guaranteed under динамическая нагрузкаing.
Vertical Pumps
Support the ротор weight and hydraulic thrust in vertical turbine pumps, deep-well pumps, and vertical mixed-flow pumps. 511 or 512 series selected based on impeller thrust calculations and pump head pressure.
Automotive Transmissions
Thrust washers and шарикоподшипники in automatic transmission clutch packs and manual transmission gear stacks. Compact 511 series for light vehicle gearboxes; 512 series for heavy commercial vehicle transmissions.
Marine Propeller Shafts
Heavy-duty 514 series упорные подшипники поглощает propeller thrust in small-to-medium vessel drive trains. Stainless steel variants available for corrosion resistance in saltwater and bilge environments.
Extruders & Injection Molding
Absorb screw thrust in plastic экструдерs and термопластавтоматs. 513 series with heavy поперечное сечение поглощаетs continuous осевая нагрузкаs during plastication and injection phases with minimal deflection.
Почему выбирают Our Упорные шарикоподшипники
Engineered with key design имеет that distinguish precision thrust шарикоподшипники for industrial applications
Separable Design
Shaft washer, корпусная шайба, and шариково-сепараторная сборка mount independently. Simplifies installation in confined spaces. Each component can be fitted with the correct interference or посадка с зазором for optimal performance.
High Axial Capacity
Optimized internal geometry and комплект шариков maximize осевая нагрузка rating. The line from light 511 to extra-heavy 514 series предлагает a 5× axial capacity range for the same размер отверстия.
Self-Alignment Option
532 and 533 series with spherical корпусная шайбаs поглощает up to 3° of static угловое смещение — protecting the bearing from краевая нагрузка and premature failure when mounting surfaces are imperfect.
Double Direction Option
522/523/524 series with two ball rows accommodate reversing осевая нагрузкаs. Essential for двунаправленная ход screws, vertical spindles with tool-change thrust reversal, and oscillating axial motion applications.
Stable at Speed
Pressed steel or machined brass cage guides balls precisely while maintaining low friction. Factory-applied preservative обеспечивает initial lubrication and corrosion protection during shipping and storage.
Premium Material
Rings and balls in GCr15 (100Cr6/52100) high-carbon хромистая сталь, сквозной закалки to 58–64 HRC. Dimensional stability heat treatment гарантирует consistent performance from -20°C to +120°C operating range.
