FAG KM25 Locknut

Locknuts can be used to locate bearings on shafts or adapter sleeves. They also give easier mounting of bearings with a tapered shaft seat and the fitting and dismantling of bearings on withdrawal sleeves. The locknuts are made from steel and the tensile strength of the material is at least 350 N/mm2. They have four or eight evenly spaced slots on the circumference into which hook wrenches or striking-face wrenches can be fitted. By agreement locknuts of series HM30-H and HM31-H with threaded holes for mounting screws are available. Precision locknuts are described in the section Bearings for screw drives.
