Rexnord-Stephan S4 Catalogue

04-2007 3P0200-XXThe S4 Product FamilyThe S4 Product FamilylStrongFeaturesThe optimized gearing and shaft geometry compensatesdeflection under load. Application-hardened, hard-machinedgear wheels correspond to high quality requirements.Gear unit casings, covers, feet, flanges, and motor casingsare heavily ribbed and securely connected to each other.Carefully dimensioned shaft and roller bearings absorb highexternal loads. The components are dimensioned to withstandpeak loads even under the most adverse operatingconditions.AdvantagesThe Rexnord-Stephan S4 transfers higher torques with agiven shaft-center distance for a long, low-maintenance servicelife.The ruggedly designed casing ensures maximum robustnessunder high load and failure-free operation.High load-carrying capacities to absorb high external forcesat the input and output shaft ensure a long bearing life ofthe Rexnord-Stephan S4 geared motor.lSilentFeaturesOptimized gearing geometry and precise abrasive engineeringpractice create a smooth rolling of the tooth flanksinvolved in the engagement.The inside of the casing was reinforced by ribs similar tothe star-shaped output cover.Using high-precision machining of the motor flange, motorand gear unit were integrated into a harmonic unit.AdvantagesThe result is a nearly perfect tooth engagement, even loaddistribution across the complete face width, minimum vibrationsand, therefore, a smooth, low-noise running.Perfectly tied-in ribs dampen vibrations and ensure thatvibrations are not passed on to the environment as noise.The pinion mounted directly on the motor shaft engages inthe gearing of the gear unit without angle error and doesnot create any disturbing noise.lStandardFeaturesConnection dimensions of shafts, feet, and flanges areidentical with those of the market standard.The Rexnord-Stephan S4 program features a broad rangeof designs and numerous standard options. Additional informationcan be found in the overview of the product program.AdvantagesThe Rexnord-Stephan S4 series corresponds to the marketstandard; based on the outstanding performance specifications,it is predestined to replace existing drives.The most economical design for the respective applicationcan be selected and is available worldwide.lSmartFeaturesThe EasyFit System:Pre-assembled gear units are factory assembled inGermany.Pre-assembled gear units, motors and wheel sets are stokkedin the Rexnord assembly centers throughout the world.Short assembly time and high part interchangeability aregranted at each assembly center side due to the uniqueEasyFit System.AdvantagesGuaranteed High Quality.Over millions of design variants can be quickly assembledthrough a corresponding combination of pre-assembly componentswhich allows for worldwide availability.Short delivery time.S7
