Overview
The Falk 1090T shaft hub coupling is a T10/T20 series steelflex grid coupling component manufactured by Falk (Rexnord). This steel hub provides a flexible, misaligned-shaft connection without creating the side loads typical of rigid couplings. The 1090T is part of Falk’s proven steelflex platform, used across manufacturing, mining, food processing, and power generation for smooth, maintenance-friendly power transmission.
Key Features
- Steelflex Grid Technology: Provides generous misalignment capacity without producing detrimental bearing side loads created by other couplings
- Standard T10/T20 Configuration: 4.880-inch outside barrel diameter with 3.88-inch length through bore for grid couplings
- Steel Construction: Steel hub material rated for industrial duty
- Multiple Bore Options: Coupling Sizes 1020T thru 1090T are generally furnished for CLEARANCE FIT with setscrew over the keyway
- Keyway Design: Finished bore with keyway, accepting standard keys for secure shaft mounting
- High Torque Capacity: Torque capacity of 33,000 in-lbs with maximum RPM of 4,000
