Parameters: maximum pressure: 1.5Mpa maximum temperature: 120 ° C maximum speed: 200rpm Suitable medium: water, hydraulic oil, coolant structural features: the HM Series rotary joint Department according to the the modern connected devices caster roll characteristics and design, it the majority of the connector molded into the inside of the roller, the only exposed outside pipe connection elbow, is conducive to the space between the distribution in the roll channel flows with the flow. Rotary joint sealing structure design, in addition to balanced seal design, but also to change the original axial tandem is a unique inverted built sealed, so that not only reduce the axial length of the shell structure and become one more conducive to joint disassembly and maintenance.
