Traditional keyed shaft-hub connections often weaken the shaft, complicate assembly and limit positioning accuracy. Taper Locking Assemblies provide a modern keyless alternative, transmitting torque through friction across the entire contact surface. This results in a strong, backlash-free connection while preserving the full mechanical strength of the shaft and ensuring outstanding concentricity.

The product range includes self-centering locking bushings for applications requiring maximum running accuracy, axially fixed designs for applications where hub movement must be avoided, low surface pressure locking assemblies for thin-walled or low-strength hubs made from materials such as aluminium or cast iron, as well as single- and three-piece locking rings for a wide variety of installation and torque requirements. Their modular design allows engineers to select the most suitable solution for each application.

As the official Hungarian partner, BIBUS Kft. provides engineering support for selecting and sizing the optimal locking assembly based on shaft diameter, transmitted torque, hub material and installation constraints. This ensures reliable, maintenance-free operation throughout the lifetime of the machine.
