Features
A high-precision lock nut: The thread and locating face are machined in the same operation. The maximum runout between locating face and thread is 0.005mm.
Locks without a locking washer and keyway: KMTA nuts lock in the same way as KMT nuts with three radial brass locking pins. There is no need for a locking washer or keyway. Expensive machining is therefore avoided and shafts can be of a smaller diameter. The brass locking pins and the thread of the nut are machined in a single operation.
Simple to align perpendicular to the shaft: The KMTA nut can be aligned perpendicular to the shaft with the same accuracy as the KMT design. The locking screws enable the nut to compensate for the inaccuracies of adjacent components on the shaft. Axial and radial runout can be minimised.
Withstands high axial loads: The KMTA design withstands the same high axial loads as the KMT lock nuts. This is because the entire length of the nut carries the working axial load.
Ensures very effective locking: The locking screws are of the largest size practicable in a nut of this design to maximise the locking force with even moderate tightening. The brass locking pins do not absorb a significant part od the total axial load on the nut so the locking forces are utilised in the best possible way.
Re-usable: The brass locking pins are not deformed when pressed against the shaft thread. The locking effect is purely as a result of frictional forces. Since the locking pins are not deformed it can be re-used without any loss of precision.
Simple to mount and dismount: The KMTA lock nut is simple to mount and dismount. The nuts all have both radial and axial holes. Hook spanners may be used on the radial holes, pin spanners on the axial holes. the locking grub screws can be tightened with either a standard hexagon key or torque wrench. A torque wrench is recommended if an accurate loosening torque limit is required.
Fine threads: KMTA lock nuts in sizes 11 to 15 have metric series fine thread pitches, these complement the metric series standard pitches of the KMT series.
