Heavy cast iron housings dampen vibration and assure bearings and gears are correctly positioned under all load conditions. The bearings Amarillo uses provide a design life many times greater than anticipated requirements. Spiral bevel gears in upper and lower gear boxes are precision machined from nickel alloy steel, case hardened and lapped in sets. Amarillo gears are designed specifically for wind machine application to provide smooth, quiet power transmission. All shafts, manufactured from heat-treated alloy steel, are sized and supported to minimize stress and deflection.
Amarillo gear boxes interchange with all domestic wind machines currently in production.
Amarillo has been the premier wind machine gear drive since 1974.
