Application

Hydraulic fitting bolts are a new fitting bolt that can be applied to flange couplings. They are normally used in propeller shafts and intermediate shaft, intermediate shaft and intermediate shaft, intermediate shaft and main engine (or reduction gearbox) output shaft connections. The hydraulic fitting bolts can be also used in steam turbine, rolling mill or other adapting pieces with a high torque.

Features

Hydraulic fitting bolts are convenient and time saving to use. There is no tapping or freezing needed during installation and disassembly. Users only need a hydraulic pump, a hydraulic elongator and simple positioning sleeves
Hydraulic fitting bolts can be used repeatedly.
