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.
