The HNBF series hydraulic nuts are mainly used for keyless connections of connecting parts. Its working principle is to use ultra-high pressure oil to generate a thrust on the shaft and a tension on the shaft sleeve, so that the shaft and shaft sleeve are uniformly connected under force. There are two ways to inject oil axially and radially, and the pressure is evenly distributed on the pressure ring. The standard working pressure is 100MPa
Scope of use: Installation and disassembly of bearings; Installation and dismantling of propellers, rudder tiles, etc; Dismantling high-pressure joint surfaces, such as train wheels, couplings, flywheels, and gears
