Product Overview: The 51118 Thrust Ball Bearing
The 51118 Thrust Ball Bearing is a precision-engineered component designed to manage purely axial (thrust) loads in a single direction. With key dimensions of 90mm bore diameter, 120mm outer diameter, and 22mm thickness, this bearing is an essential part of our 51100 Series, which falls under the broader Thrust Ball Bearings category. Its design consists of three separable parts: a shaft washer, a housing washer, and a ball and cage assembly. This separability simplifies the mounting and dismounting process, making it a convenient choice for various industrial applications.
As a specialist supplier of industrial components, we provide high-quality 51118 bearings that adhere to strict manufacturing standards. These bearings are indispensable in machinery where rotational components are subjected to significant axial forces, ensuring smooth operation and preventing premature wear on associated parts. They are not suitable for radial loads but excel in their designated thrust-handling role.
Key Features of the 51118 Bearing
- Separable Components: The shaft washer, housing washer, and ball cage assembly can be mounted independently, facilitating easy installation and maintenance.
- Axial Load Support: Specifically designed to accommodate high axial loads in one direction, providing stability for vertical shafts and similar applications.
- High Precision: Manufactured to tight tolerances to ensure smooth, low-friction performance and consistent operation.
- Durable Construction: Made from high-quality bearing steel for exceptional hardness, wear resistance, and a long service life under proper operating conditions.
- Open Design: Allows for easy lubrication and inspection, which is critical for maintaining performance in demanding environments.
- Standardized Dimensions: Conforms to industry-standard dimensions for easy interchangeability with existing parts.
Common Applications
- Industrial Gearboxes: Provides support for shafts subjected to axial forces from helical or bevel gears.
- Machine Tool Spindles: Used in drilling machines, lathes, and milling machines to handle the axial forces generated during operation.
- Crane Hooks and Swivels: Essential for managing the heavy vertical loads in lifting and material handling equipment.
- Vertical Shafts: Ideal for supporting the weight and operational thrust of vertical pumps, motors, and generators.
- Automotive Applications: Commonly found in clutch release mechanisms and steering pivots.
- Jacks and Screw Mechanisms: Provides the necessary support for high-thrust applications in lifting jacks and screw presses.
- Rotating Tables and Indexing Fixtures: Ensures smooth rotation while supporting heavy axial loads in manufacturing and assembly equipment.
