Product Overview: The 51120 Thrust Ball Bearing
The 51120 Thrust Ball Bearing is a precision-engineered component designed to manage purely axial (thrust) loads in a single direction. With dimensions of 100mm Bore Diameter, 135mm Outer Diameter, and 25mm Thickness, this bearing is part of our robust 51100 Series within the broader Thrust Ball Bearings category. Its design consists of three separate parts: a shaft washer, a housing washer, and a ball and cage assembly. This separable construction simplifies mounting and dismounting, making it ideal for applications where components need to be installed independently. The 51120 is specifically engineered for high axial stiffness and is an excellent choice for machinery requiring reliable support against thrust forces along a rotating shaft.
Key Features of the 51120 Bearing
- Single-Direction Axial Support: Specifically designed to accommodate high axial loads in one direction only.
- Separable Components: The shaft washer, housing washer, and ball cage assembly can be mounted separately, simplifying installation and maintenance procedures.
- High Axial Stiffness: Provides firm and stable support, minimizing axial deflection under load.
- Precision Manufacturing: Produced to strict industry standards for dimensional accuracy and consistent, reliable performance.
- Low-Friction Operation: The ball and cage assembly is designed for smooth rotation, reducing operational torque and heat generation.
- Durable Construction: Made from high-quality bearing steel to ensure a long service life and resistance to wear.
Common Applications
- Industrial Gearboxes: Provides axial support for gears and shafts, ensuring proper mesh and load distribution.
- Machine Tool Spindles: Used in drilling machines, lathes, and milling machines to handle axial forces from cutting tools.
- Vertical Shafts: Ideal for supporting the weight and operational thrust of vertical pumps, motors, and agitators.
- Automotive Clutches: Manages the axial force required for clutch engagement and disengagement.
- Lifting Equipment: Employed in crane hooks, jacks, and other lifting mechanisms to support heavy axial loads safely.
- Rotating Tables & Turntables: Ensures smooth and precise rotation in indexing tables and other positioning equipment.
Benefits of Using the 51120 Bearing
- Enhanced Equipment Stability: The high axial rigidity prevents unwanted movement along the shaft, improving overall machine precision and reliability.
- Simplified Installation: Its separable design allows for easier and more flexible mounting compared to non-separable bearings.
- Cost-Effective Load Management: Offers an economical and reliable solution for managing purely axial loads without the complexity of combined load bearings.
- Increased Service Life: High-quality materials and design reduce wear and tear, leading to longer operational life and fewer replacements.
- Interchangeability: Manufactured to standard dimensions, allowing for easy replacement and interchangeability with bearings from other manufacturers.
- Reliable Performance: Delivers consistent and dependable performance in applications with moderate speeds and high thrust loads.
