  • Handles up to 2,340 in-lb torque for heavy-duty power transmission
  • Operates at speeds up to 3,750 RPM for high-speed machinery
  • Precise bore tolerance of +.0005 to +.0020 in ensures secure shaft fit

Sleeve Coupling Flange Size 9

The Tb Wood'S 9S214 is a cast-iron flange hub designed for power transmission in compressors, conveyors, motors and pumps. It accepts a 2-1/4 inch round keyed bore with a tolerance of +0.0005 to +0.0020 inch for a precise shaft fit.

Build Integration Requirements

This component operates at a maximum speed of 3,750 RPM and transmits up to 2,340 in-lb of torque. The hub diameter measures 3 5/8 inches with a hub body length of 25/32 inch, while the overall length through the bore is 2 13/32 inches.

Upgrade and Replacement Context

It replaces worn or damaged flanges in existing Sure-Flex coupling assemblies where the bore size and coupling dimensions match. The jump is worth it when the current hub shows keyway wear, corrosion or cracking that compromises torque transfer. Buyers needing a different bore diameter or a larger coupling size cannot use this part.
