The new H series of horizontal-type helical gearboxes are high-quality gearboxes for heavy-duty industrial applications. All mechanical parts are analyzed with state-of-the-art software to guarantee their reliability. The new H series is optimized for power density, i.e. to achieve the highest rating at the smallest possible dimensions. But because high power density also means increased thermal load, the new products are provided as standard with various cooling options. Efficiency is further enhanced through the use of high-grade lubricants and seals. Another advantage is the wide range of mounting possibilities: The units can be mounted on any side, directly to the motor flange or to the output flange, greatly simplifying their installation. Because these gear units can be mounted on any side, additional equipment, such as integrated or external forced lubrication or oil expansion tanks are available as accessories. Yilmaz Reduktor also offers tailored solutions for specific applications. Our standard range includes reinforced bearing arrangement or extended bearing distance for high radial load or agitator applications, backstops for single-direction applications such as conveyors or elevators, brakes for hoisting or moving applications, and shrink disks for alternating loads. Special solutions for extruder applications are provided for each size and ratio.
