When specifying a sheave, which factor do you NOT consider?

When specifying a sheave, the factor that typically is not considered is the lubricant. The primary focus when selecting a sheave revolves around its material composition, the specific purpose or type of belt it will accommodate, and the number of grooves necessary for proper belt function.

The material is vital because it directly impacts the sheave's durability and performance in relation to the types of forces it will encounter. The purpose, or the type of belt, is essential as it determines the dimensions and design features necessary for efficient power transmission. The number of grooves affects how the sheave interacts with the belt, ensuring proper engagement and minimizing slippage.

Lubrication, while important for the bearings or friction points in a drive system, does not affect the sheave's specification itself. It is an operational consideration rather than a specification of the sheave's physical design or the engineering requirements for its function. Thus, lubricant typically does not influence the fundamental selection criteria for sheaves.
