CURVED JAW SHAFT FLEXIBLE COUPLINGS TYPES
GR, GESM, GESA

SIMPLE LOW COST COUPLINGS FOR SHAFTS 4 TO 90MM

Techdrives offer 3 types of curved jaw flexible shaft couplings for torques 1.2 to 1465Nm and shaft diameters 4 to 90 mm.  Two different grades of flexible elements are offered to vary the torque rating and the stiffness.  Dimensions match European standards and parts are interchangeable.


Type GR: Simple low cost couplings with a good torque capacity, torsionally soft with some backlash

Type GESM: Precision machined clamp hubs give zero backlash and shaft connection without keyways.

Available sizes 7 to 42 for torques 0.65-187Nm

Type GESA: Backlash free high-torque design with steel clamping hubs.  Sizes 14-42, torques 7.5 to 450Nm.

Construction: Hubs in cast iron or aluminium, elements are polyurethane.  A stock range of finished bores with keyways is available, see the download.
