General data: 4 sizes. Ratio either 1 : 1 or 2 : 1. Any mounting position possible. Input shaft / output shaft, speed: At both types and both ratios, the input can be at shaft A as well as at shaft B. At ratio 1:1 the maximum speed is 1400 rpm. Ratio 2:1 can be used for gearing down and also for gearing up. Gearing down: Input at shaft A with max. speed 1400 rpm (output speed max. 700 rpm). Gearing up: Input at shaft B with max. speed 750 rpm (output speed max. 1500 rpm). Housing: Thick-walled, one-piece cast aluminium housing, fully oil-tight and dust-proof. Gearing: The gears are to the Coniflex system, case hardened. Shafts/bearing system: Input and output shaft are ground and mounted on ball bearings. From size 2 with keyways.Lubrication/maintenance: Lubricated for life, viscosity ISO VG 150. Gearboxes are maintenance free. Angular backlash: 15 to 30 angular minutes. Permiss. operating temperature: -18°C to +80°C. * Permiss. radial force for FA=0. ** Permiss. axial force for FR=0.
