Z2 Locking Device Instead of as SeriesTanso Shaft Locking Devices are designed to connect hubs firmly to shafts using a keyless mechanical interference fit, enabling the transmission of torque or withstanding axial thrust. This mechanism works by converting screw tension into radial pressure through an inclined plane, which expands the locking device and eliminates the gap between the hub and the shaft. The friction bond between the locking device and the shaft/hub creates a zero backlash connection that is easily releasable. These devices provide a more efficient alternative to traditional interference fits, allowing for easier installation and removal while also offering higher contact pressures. This means they can transmit more torque or allow for shorter hubs. The ease of installation also enables more precise positioning of the hub on the shaft, facilitating angular timing. The assembly and disassembly process is straightforward, requiring only common tools to lock and unlock the clamping screws. A torque wrench is typically needed only when high precision is required. Tanso Shaft Locking Devices offer superior holding power compared to standard keyed hubs, and they include overload protection features that prevent damage if the pre-set torque is exceeded. However, it's important to note that excessive slipping can cause damage since these units are not friction couplings. Additionally, the design allows for easy adjustment, enabling the hub to be clamped at any position along the shaft without the need for lock washers, spacers, or stop rings. This makes them ideal for applications where flexibility and accuracy are essential. Z2 Locking Device Instead of as Series
