Rexnord 200-SER-54 Insulated Flexible Disc Coupling

Rexnord 200-SER-54 Insulated Flexible Disc Coupling is a 200-size Thomas Series 54 disc coupling with an electrically insulated center member and shaft bores of 1-3/8 in and 1-1/4 in. This coupling, part of Rexnord's Series 54 family, transmits torque between rotating shafts while accommodating angular, parallel, and small axial misalignment in demanding process and power-transmission equipment. The ELEC designation denotes electrical insulation between the center member and hubs, preventing current from traveling through the shaft train in installations requiring isolation. Designed as a compact, torsionally flexible connector, it pairs with Rexnord hubs and a disc pack to support pumps, compressors, fans, and other industrial machinery where space is limited and precise shaft alignment must be maintained. The 200 size and Series 54 configuration reflect a common Rexnord solution for industrial drives seeking reliable disc-coupling performance.
