Coupling SIze KE Series Elastomeric Couplings 6 The KE coupling is a general-purpose flexible coupling, fully interchangeable with the standard couplings frequently used throughout the industry. The coupling consists of two machined cast iron hubs connected by an elastomeric gear ring. Available in 8 basic sizes, with torque capacity to 3300 Nm, the KE coupling provides positive power transmission between shafts, combined with the ability to accommodate moderate levels of misalignment. KE couplings are designed to transmit torques equal to the capabilities of sizes of commercial shafting...

8 Misalignment Maximum angular misalignment is 1°, but for maximum life angular misalignment should not exceed 1/2°. Refer to sketch on right, where .009mm per mm root dia. is equivalent to 1/2° angular misalignment. B – A = .009 x C. Offset or Parallel misalignment should not exceed 2% of chain pitch.

12 GFA and GFAS Gear Couplings Coupling types GFA and GFAS are designed for heavy industrial applications, providing a torsionally stiff connection of shafts which can accommodate angular and parallel misalignment and axial movement. The GFA coupling consists of two hardened steel hubs with external crowned and barrelled gear teeth, connected by a hardened steel sleeve with matching gear teeth. The hub teeth are positioned a maximum distance apart to minimise angular and parallel misalignment. The double articulation in the GFA series permits high misalignment. The GFAS coupling has only...

The GF Coupling consists of two steel hubs with external crowned and barrelled gear teeth, phosphated for corrosion protection, connected by a synthetic resin sleeve. The sleeve is manufactured from high molecular weight polyamide, thermally conditioned and impregnated with solid lubricant to provide a long...
