Flexible coupling - Spider (jaw) coupling

The spider (jaw) coupling is a material flexing coupling that transmits torque thru compression of an elastomeric spider insert placed between two intermeshing jaws. 

• Flex element is commonly made of NBR, polyurethane, Hytrel or Bronze

• Accommodates misalignment

• Transmits torque

• Used for torsional dampening (vibration)

• Low torque, general purpose applications

• Can isolate electrically between drive and driven shaft

• Can fail in case of a sever overload, thus protect machine components
