GN 2248 High Response Couplings Aluminum, Vulcanized, Vibration-Damping, with Clamping Hub

High Response Couplings GN 2248: Aluminum, Vulcanized, Vibration-Damping, with Clamping Hub
Overview of Couplings General Information for Couplings Mounting Information for Couplings Technical Information for Couplings ISO Fundamental Tolerances Plastic Characteristics

Product description

High response couplings GN 2248 transmit angular positions and torques with high precision and zero backlash. The elastomer element bonds the clamping hubs together, compensating for shaft misalignments and runout tolerances. The clamping hubs ensure easy installation.

High response couplings GN 2248 are primarily used in applications where precise position and motion transmission is required, e.g., in drive technology on test benches or similar applications.
