Overview
The Rexnord 0744100 is an original manufacturer spacer hub designed for T31:T35 series grid couplings in the 1060 coupling size class. This genuine Falk Steelflex component features a center line (CL) dimension of 5.969 inches and is engineered to span the DBSE (double bore, single extension) configuration in spacer-style flexible coupling assemblies. Supplied new in original packaging, this hub is a direct OEM replacement for worn or damaged spacer hubs in existing installations.
