Coupling types GFA and GFAS from Cross+Morse are designed for heavy industrial applications. The GFA coupling consists of two hardened steel hubs with external crowned and barrelled teeth connected by a hardened steel sleeve with matching gear teeth. The GFAS coupling has only one hub with external teeth which connects to a sleeve with integral hub. This povides a stiffer connection suited to cardan shaft applications. High torque capacity coupling for medium speed applications, up to 6,000 rpm. Torsionally stiff. Require good alignment for long service life. Use Gear couplings:- For high torque reversing drives on Cranes, Rolling Mills, high shock load applications, Crushers, Rubber Mills, large Motor Gearbox connection and Drives requiring torsional stiffness.
