Lock nuts with a locking screw

KMFE series lock nuts (fig. 1) use an integral grub screw (locking screw) to press the threads on the nut against the threads on a shaft (fig. 2) or sleeve. Lock nuts in the KMFE series are intended to axially locate CARB toroidal roller bearings, sealed spherical roller bearings and sealed self-aligning ball bearings on a shaft or an adapter sleeve.
KMFE lock nuts should not be used on shafts or adapter sleeves with keyways or key slots. Damage to the nut can result if the locking screw aligns with a keyway or slot.
