Overview
The Falk Rexnord 1030T31 spacer hub is a premium grid coupling component engineered for industrial power transmission and machinery alignment. This spacer hub accommodates a 1-5/8″ (1.625″) bore diameter and functions as part of the Falk Steelflex T31:T35 series, allowing flexible connection between two shafts while compensating for minor misalignment. The solid steel construction ensures durability in demanding manufacturing, motion control, and automation environments.
