TEXROPE®synchronousbeltsarecharacterisedby:
•apositivedrivewithhighpositioningaccuracy
•capableofhighlinearvelocityandareducedinertia
•ahighefficiency(98%)duetoahighflexibilityandlowertension
•nometaltometalcontactreducingnoiselevels
•nolubricationorretensioning(minimummaintenance)
•alightandcompactpulley/beltsystem
This manual covers two calculation procedures: one for TEXROPE® STB, TEXROPE® SupraDrive™ and TEXROPE® ExtraDrive™ and one for TEXROPE® LL belts. It gives all the necessary information for a complete calculation procedure.Thanks to their superior performance, TEXROPE® STB, TEXROPE® SupraDrive™ and TEXROPE® ExtraDrive™ belts take a major place in this manual.
