Half Couplings

Shaft Half Couplings & Bobbin Spacers

Henley’s Propellers and Marine custom half couplings are manufactured in either cast-iron or medium tensile steel (¾” to 2″ cast-iron and 2″ to 4″ medium tensile steel) to suit the output flange of any standard gearbox flange and or the PCD, spigot of an Isoflex coupling.

  • All Henley couplings are chromed for rust resistance.

  • All Henley couplings are tapered and keyed to ensure correct and secure fit.

  • If we supply the shaft then half coupling is tapered, keyed and lapped to match.

  • For non-standard flanges a drawing should be supplied to allow a half coupling to be manufactured.

Henley’s also custom build bobbin spacers should a gearbox oil pump foul the application of a Isoflex coupling and or to better match the PCD / Spigot of gearbox output to the required dimensions of the shaft half coupling.
