Conical-cylindrical gearboxes series RXO /TR for cooling tower and RXO /CR for air-cooled condensers (ACC) from STM, these are high-tech and reliable mechanical transmissions for performing specialized tasks of this type. The optimized design and balance of the components allows the load to be evenly distributed over the entire unit to ensure maximum stability in operation.
The housing of this line of gearboxes has high rigidity, reinforced roller bearings are installed to increase the load capacity. In general, the design, technology and materials used in the series guarantee resistance to significant radial and axial loads.
Optionally, the gearboxes can be equipped with vibration, temperature sensors, lubricant indicators, hydraulic switches, forced cooling and lubrication system, etc.
