5 mm to 8 mm Rigid Sleeve Shaft Coupling

Designed to provide a solid connection between a 5 mm shaft and an 8 mm shaft, this rigid sleeve coupling delivers direct torque transmission without any flexible elements. It is intended for applications where both shafts are accurately aligned and a rigid mechanical connection is required.

Machined from aluminium alloy using CNC manufacturing, it combines low weight with good mechanical strength and precise dimensions. Its sleeve-style design provides uniform shaft engagement for secure power transmission. Because it is a rigid coupling, it does not compensate for shaft misalignment, making correct installation essential for reliable operation.
