Curved jaw shaft couplings for shafts 4 to 90 mm | Techdrives


	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 aluminum, elements are polyurethane.
