KMT and KMTA Precision Lock Nuts are used to locate bearings in machines and equipment that require high precision such as lathes, grinders, milling machines, motors, shut-off valves, spindle and ball screws.


These nuts have 3 brass pins angularly distributed around its circumference which are tightened against the shaft by screws. The pins are machined to match the shaft thread and its tilt is equal to nut thread angle so the nuts are not subject to axial loads or deformation, allowing locking in the exact position. Although they use the same locking system, the KMT and KMTA nuts differ by the external profile and tightening tools required.


Precision lock nuts are made of Carbon steel as standard with optional choice of Stainless Steel.


Assembling

The KMT nuts are usually mounted with hook spanners, however, sizes up KMT 15 can be mounted using wrenches. The KMTA are mounted using pin wrenches or a pin-type face spanner and both of them are equipped with through-body screws. Once assembled, the bolts should be tighten lightly until each brass pin touches the shaft thread and only then tighten the screws alternately with a torque wrench until the recommended torque value is achieved for all the three bolts.


Removal

When removing the precision nuts KMT and KMTA, first loosen the three screws. Note that the brass pins can still be attached to the shaft thread, in order to proceed, tap the nuts near the pins using a copper or rubber hammer to loosen them. Only then remove the nut.
