Mechanical Expansion Sleeve

Mechanical expansion sleeves are connection components that achieve precise positioning and efficient transmission locking through mechanical assembly. Featuring a compact structure, Typically composed of a steel outer shell with an internal tapered or wedge-shaped structure, installation requires no heating or adhesives. Simply tightening the nuts or matching bolts causes the inner wedge elements to expand uniformly and tightly conform to the shaft diameter, forming a secure, stable friction fit between the expansion sleeve and the connected components.

This design ensures high torque transmission capacity and smooth radial/axial positioning accuracy, making it ideal for high-precision machinery such as printing presses, slitting machines, coil handling equipment, and calenders. It proves particularly efficient in applications involving frequent roller or shaft replacement.

As a specialized manufacturer of mechanical expansion sleeves, we offer multiple diameter specifications, lengths, material grades, and surface treatments (e.g., chrome plating, polishing) to meet diverse equipment and operational requirements.

Mechanical expansion sleeves facilitate rapid installation/removal, simplify maintenance, and deliver stable performance, making them a critical component for enhancing production efficiency and minimizing downtime.
