Overview
The Falk 1030T Grid Steelflex Coupling is a close-coupled Type T10 flexible coupling manufactured by Falk (Rexnord). This grid-based coupling element provides smooth, reliable torque transmission while accommodating minor shaft misalignment. Engineered for industrial automation, machine tool drives, and motion control systems, the 1030T delivers long service life when properly lubricated with Falk Long Term Grease (LTG).
