Understanding 51118 Thrust Bearing Key Features and Applications

Thrust bearings are a critical component in various mechanical systems, designed to support axial loads while allowing for rotational motion. Among the various types available in the market, the 51118 thrust bearing stands out for its unique design and application versatility. In this article, we will explore the key features of the 51118 thrust bearing, its benefits, and where it is commonly used.

What is a 51118 Thrust Bearing?

The 51118 thrust bearing belongs to the category of thrust ball bearings, which are specifically crafted to accommodate axial loads in one direction. A typical 51118 thrust bearing consists of a flat housing, rolling elements (balls), and a series of rings that form the inner and outer races. Its design allows for efficient load distribution, ensuring that forces are evenly spread across the contact surfaces.

The designation ‘51118’ refers to the specific dimensions and loading capacity of the bearing. This particular bearing has an inner diameter of 90 mm, an outer diameter of 125 mm, and a width of 25 mm. These dimensions make the 51118 bearing suitable for applications where space is limited but reliable performance is essential.

Key Features
