Precision lock nuts with locking pins
KMT and KMTA

Metric thread: ISO 965-3

Metric thread, 5H: ISO 965-3
Maximum axial run-out locating face/thread (sizes ≤ 40): 0,005 mm

Metric thread, 6g: ISO 965-3
Trapezoidal thread, 7e: ISO 2903

KMT and KMTA lock nuts are locked on the shaft (sleeve) by friction The friction, and
therefore the loosening torque, varies as a result of the accuracy of the tightening torque
of the grub screw, the surface inish of the shaft thread, the amount of lubricant on the
thread, etc KMT and KMTA lock nuts should be properly mounted to threads that are dry
or only have a minimum amount of lubricant on them
Providing that they are properly mounted to a dry or minimally lubricated thread, expe-
rience has shown that SKF KMT and KMTA lock nuts have suficient locking for typical
super-precision and general rolling bearing applications
