Spacer bushings

Expansion sleeves are mechanical components designed to mount and secure bearings on a shaft in industrial constructions. The category refers to components used in assemblies where a firm connection between the bearing and the shaft must be ensured.

The function of these sleeves is to create a reliable interface between the bearing and the shaft, enabling the transmission of torque and maintaining the required axial position of the bearing. The design principle typically uses expansion or tapered surfaces to ensure a secure clamping.

Expansion sleeves are designed with regard to operational loads and resistance to wear and corrosive environments; therefore metal materials and precise machining are commonly used to achieve the desired mounting properties.
