ETP locking bushes, also known as friction locking assemblies and friction joints give advantages at assembly and disassembly. The single Screw express and Techno models are particularly easy and fast to use. In all cases the ETP locking bush is enclosed and self-contained.
During assembly the ETP bush can readily be set to gently grip the shaft so that precise axial and radial positioning is possible. During disassembly the self-contained designs return to their original dimensions making release simple. ETP bushes can be remounted time and time again.
As ETP locking bushes remove the need for keyways, shafts can be stronger or possibly smaller in diameter. There are no points of high stress concentration. The problem of key fretting on reversing drives is eliminated.
