GR Coupling - Rotex/KTR coupling - EN8

GR Coupling (Rotex/KTR Type) – EN8 Steel | Flexible Jaw Coupling

GR Couplings are flexible jaw couplings of the Rotex/KTR type, manufactured from EN8 medium-carbon steel for high strength and durability. They consist of two steel hubs and a flexible spider insert (sold separately) that transmits torque while accommodating angular, parallel, and axial misalignment. Widely used as a direct replacement for Rotex and KTR brand couplings.
