Grid coupling series X

A general purpose, lubricated design that combines the economy and the high torque capacity of a gear coupling, combined with the torsional flexibility of an elastomer coupling. Backed by a 5-year lubrication warranty, David Brown grid couplings require no periodic maintenance when lubricated with David Brown LTG (Long Term Grease) at installation. Featuring 25 sizes, grid couplings can accommodate torque loads of 932,000 Nm and shaft diameters of 508 millimetres.
