Question

In a BUSH BEARING assembly, the inside of the bush is bored as a fit for .........

• A. Foundation bolt
• B. Sole
• C. Shaft
• D. Recess

Hint:

In bush bearings, the inner diameter matches the shaft size—it’s a precision fit for smooth rotation.

Answer 1

The Correct Option is C

A bush bearing is a type of sliding contact bearing, often cylindrical in shape, which is used to support a rotating shaft.
The bush is inserted into a housing and has an internal cylindrical surface that is bored to a specific dimension.
This inner surface is made to snugly fit a shaft, which rotates or slides inside it.
The function of the bush is to reduce friction and wear between the rotating shaft and the stationary housing.
- Foundation bolt, sole, and recess have different roles in mechanical assembly and do not interact with the bush in this way.
Hence, the inside of a bush is bored precisely to fit the shaft.
