Part Number 68514436714, SC Type Spacer Coupling Hubs without Keyway, Standard Length - Inch (Imperial) Bores
Specifically designed for the pump industry, this coupling accommodates industry standard as well as special pump/motor separation
This shaft separation facilitates easy pump repair of pump packing, bearings, and seals without disturbing pump or motor mounting and alignment
The SC Type coupling consists of two flanges, a sleeve and two shaft hubs
Quick Coupling Removal
The center drop out section consists of two flanges and the flexible sleeve
The flange is bolted to the shaft hub with four hex head cap screws
The center drop out section can be removed by removing the hex head cap screws
Flats on each hub provides a convenient grip for a wrench in order to facilitate loosening of the screws and, if desired, turning of the pump/motor shafts
Once the hub is removed from the pump shaft, maintenance on the pump can be done without disturbing equipment alignment
