RT Series Worm Gearboxes
Varvel
Engineered to simplify power transmission in tight installations, the Varvel RT Series Worm Gearboxes provide reliable speed reduction and torque delivery without unnecessary complexity. Covering seven frame sizes (RT 3 through RT 150) and handling up to 12.5 kW of input power, these single stage worm units adapt seamlessly to foot, flange, torque arm, or shaft mounted configurations. The straightforward design and universal mounting make system integration and maintenance both fast and predictable.
Features of The RT Series
The RT Series relies on a hardened, ground alloy steel worm shaft paired with a bronze alloy worm wheel for inherently quiet, low backlash operation. For sizes RT 3–85, the housing is die cast aluminium to keep weight down and resist corrosion; from RT 110 up, a cast iron body adds rigidity where higher torques demand it. Each gearbox is factory filled with ISO VG 320 synthetic oil and sealed for life, which delivers up to 15 000 hours of maintenance free service. Internal ball or roller bearings and choice of NBR, Viton, or silicone seals protect the gearing from dust and moisture, while external cooling ribs help dissipate heat under continuous duty. With IP66-rated bodies and standard IP20 motor adapters (upgradeable as needed), the RT Series stands up to a wide variety of industrial environments.
