The TSUBAKI Jaw Flex Coupling L Series hub is one half of a jaw coupling assembly. Two hubs with interlocking jaws are joined through an elastomer spider that cushions shock, damps vibration and accommodates small misalignment. The design is simple and fail-safe, making it popular on pumps, fans, compressors, gearboxes and general motor drives.
