8 Bolt Couplings
Eight bolt couplings are used on eight bolt hole gearbox output flanges. Spigots or pilots can be either male or female. Isoflex couplings are configured to the most common flanges. On Isoflex 8 bolt couplings, special steel spigots, pilots or registers are fitted to maintain absolute dimensions.
Note: certain couplings need a T-bush kit. Isoflex can supply certain adapters.
