Advantages of Shrink Fit Bushings

Shrink fit bushings, also known as shrink sleeves, are primarily used as connecting components in drive systems. One of their key advantages is that they do not require bolts for fastening. Instead, they are secured by pressure. When the pressure reaches a certain level, the bushing can automatically detach, which helps protect the drive components effectively.

Advantages of Shrink Fit BushingsThe use of shrink fit bushings relies on the connection between the shaft and the hub. Under axial force, the outer sleeve of the bushing shrinks and expands, which enables a strong frictional connection between the shaft and the hub, facilitating rotation. The primary material used for manufacturing shrink fit bushings is bearing steel, which undergoes high-frequency quenching treatment. This process enhances the bushing’s fatigue resistance and wear resistance, ensuring excellent hardness and durability for the final product.

In summary, shrink fit bushings provide strong mechanical connections, high fatigue and wear resistance, and better overall performance due to their robust design and material properties.
