Product Features: STM-piece pressure cylinder is also called composite pressurized cylinder, because its structure is very simple and lightweight, it is widely known as the "mini-pressurized cylinder" fit in the installation space is limited and is not required to contribute not great occasions. The action is fast, simple and contribute to smooth operation, easy maintenance applies to: molding, plastic welding, riveting electronic components, sheet metal molding and other occasions Installation: dress (front axle down output) Operating conditions: Product Name: STM monomer type pressurized cylinder actuator ways: double action operation conditions: 0.2-0.8 MPa air filter anti-wear hydraulic oil: ISO VG 68 # anti-wear hydraulic oil Working temperature: -5 ~ + 60 ℃ operating speed: 50 ~ 700mm / s Cylinder pressure: 30MPa cylinder pressure: 1.2MPa stroke Tolerance: + 1.00mm Operating frequency: 25 ~ 40C / min
