Couplings connect parallel offset shafts.
Electronic Components & Devices

Couplings connect parallel offset shafts.

Schmidt Offset Couplings are suited for parallel offset shaft applications where misalignments may be encountered. Products impose no sideloads on shafts or bearings and eliminate radial shaft vibration. Increasing offset distance does not result in performance loss. Available for shaft displacements of 0.156-17.29 in. and torque capacities from 55-459,000 in.-lbs, couplings maintain undisturbed...

Keyless Shaft Connections lock parts in position.
Construction Equipment and Supplies

Keyless Shaft Connections lock parts in position.

ETP shaft connections slide onto shaft and provide solid keyless connection between shaft and hub to position and lock pulleys, sprockets, and gears. They eliminate need for keyways, tapers, and tapped holes, which can cause component stress and wear. Connections have double walled steel sleeve filled with pressure medium that expands when compressed by screw tightening mechanism. They are...
