MD Flex Flyer Gear-Type Coupling
MD Flex Flyer Type J Sure-Flex Couplings are supplied with die cast alloy flanges and are bored-to-size. Normally, they employ the one-piece JE sleeve, or the one-piece JES sleeve with saw cut to permit replacement where there is insufficient gap between shafts. Spacing between internal flange hubs equals G. Spacing between shafts should be greater than 1/8 in. and less than L minus the sum of the two bore diameters.
The rubber element allows four-way flexing so couplings can take on parallel, angular, axial and torsional misalignment, plus, dampen vibration and shock. With no metal-to-metal contact, there's no need for lubrication. Couplings have a key-way with ANSI dimensions to provide a more secure hold on keyed shafts. To create a complete coupling, order two hubs and one rubber center. To order complete couplings, specify coupling size with flange symbol (J) giving bore and keyseat.

MD Flex Flyer Sleeves are available in three materials (EPDM rubber, Neoprene and Hytrel) and in three basic constructios (eight types). Characteristics of the marerials are given in the product page of each sleeve.
