The Hub City Hub Flex coupling is a revolutionary coupling design that offers many advantages
over traditional coupling designs. Like other flexible couplings, it is made up of two hubs and an
element or “insert”. It is similar in appearance to a jaw coupling, but there is no metal-to-metal
contact, which means if an element fails the hubs will not destroy each other or, worse, cause
damage to the machinery. What makes this coupling so unique is how quick and easy it is to
replace a damaged element.
