Suitability and function
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 mounting and dismounting 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.
Locknuts with threaded holes for mounting screws are available by agreement. These locknuts have the suffix H.
Precision locknuts are described in a separate publication TPI 123.
