TRASCO couplings type GRB are manufactured in cast iron GG25. They combine the typical high performances of standard couplings with the mounting and dismounting advantages offered by the SER-SIT taper bush: - they are ready to be mounted; - they are manufactured in two different executions: B1 and B2 • they solve the problem of fretting corrosion; • hubs type B1 may be axially moved for spider replacement; • they may be used in all types of machinery.
