Product Overview: The 51148M Thrust Ball Bearing
The 51148M is a high-capacity single-direction thrust ball bearing, meticulously engineered to manage heavy axial loads in one direction. As a key component in our 51100 Series of Thrust Ball Bearings, it features standard dimensions of a 240mm bore diameter, 300mm outer diameter, and 45mm thickness. This bearing's design consists of three separable parts: a shaft washer, a housing washer, and a ball and cage assembly, which simplifies mounting and inspection procedures. The 'M' suffix signifies a robust machined brass cage, offering superior strength and performance, especially in demanding, high-speed applications.
Key Features of the 51148M Bearing
- Single-Direction Axial Load: Specifically designed to accommodate heavy thrust loads in a single direction, ensuring stability in vertical shaft applications.
- Separable Components: The shaft washer, housing washer, and ball cage assembly are separate, allowing for straightforward installation, removal, and maintenance.
- Machined Brass Cage (M): Provides excellent durability, low friction, and is capable of withstanding high speeds and operating temperatures.
- High Precision: Manufactured to exacting standards to ensure smooth, low-friction rotational performance and precise axial shaft location.
- Simple Design: Its straightforward construction makes it an economical and reliable solution for managing purely axial forces.
Common Applications
- Heavy Industrial Gearboxes: Provides axial support for gears and shafts, preventing movement under heavy loads.
- Vertical Shafts: Ideal for applications such as turntables, rotating platforms, and indexing tables where the primary load is axial.
- Crane Hooks and Swivels: Used in lifting equipment to handle the immense thrust loads generated during operation.
- Extrusion Machinery: Supports the screw shaft in plastic and metal extruders against high axial pressure.
- Machine Tool Spindles: Ensures precise axial positioning in lathes, milling machines, and drilling equipment.
- Industrial Pumps and Compressors: Commonly found in vertical pump assemblies to support the impeller shaft.
