Flexible Gear Couplings
Flexible Gear Couplings is continued trouble-free operation of directly-connected. Independently installed equipment is dependent on the protection of shaft bearings and other expensive machine components form reactive forces resulting from offset and/or angular shaft misalignment and end float.

With the most exacting precision in the original installation subsequent mis-alignment can rarely be avoided as foundations may settle, bearings ultimately wear and dimensions change with temperature, vibrations can also affect alignment.





SERIES 100 FULL GEAR COUPLING FG-XXX

The standard series 100 full gear coupling, the type used on most industrial applications, is the double engagement forged steel coupling. it will compensate for both parallel (offset) shaft misalignment and angular misalignment and has a large end float capacity. it transmits heavy duty loads when selected and applied correctly. standard couplings come with exposed bolts but shrouded bolts beyond fg-110 can be supplied at no extra cost.

The hubs are reversable and the reversed position permits a larger Shaft separation and this finds great application when using tapered shafts as found on most large centrifugal pumps, compressors, generators and steam turbines. These gear couplings are generally supplied with rough bores and can be supplied with finished bores as well.

Series 1100 FULL GEAR COUPLING FG-XXX

The standard series 1100 full gear coupling, are very much similar to the series 100 couplings, the only difference being the sealant arrangement which is provided as a detachable end cover, this eases the installation and maintenance for greasing in applications where there is a space constraint between hub face and the equipment. all standard couplings beyond fg-110 & fgz 210 come in this fashion. ail sizes of series 100 are also available with this arrangement on request.
