'GF' Series Polymer Gear Couplings

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 maintenance-free life. This sleeve has high resistance to atmospheric humidity and an operating temperature range of –20°C to +80°C with ability to withstand 120°C for short durations.

The GF Series Couplings are made with two hub lengths; a standard hub suitable for most applications, and a longer hub (ref GFL) designed to fit full length of shaft on standard motors. Hubs of different lengths can be combined in one coupling.
