FAQ What is the correct tightening torque for the akn ZMA 50/92?The tightening torque depends on the specific application, bearing preload, and lubrication. It is crucial to consult the machine’s technical manual or akn’s official documentation. Generic values should not be used for precision applications. What is the function of the set screws on this lock nut?The set screws are used for axial locking. After the nut is tightened to the correct preload, these screws are tightened against the shaft thread to prevent the nut from backing off or loosening due to vibration or operational stress. Is a special tool required to install this lock nut?Yes, a hook spanner (or C-spanner) that fits the four slots on the nut’s outer diameter is required for proper installation and tightening. Using improper tools like a hammer and chisel can damage the nut and the bearing. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
