COUPLINGS Type S Sure-Flex couplings are normally supplied with the two- piece E sleeve. However, any of the sleeves shown on page F1—5 can be used with Type S flanges. Spacing between internal flange hubs equals L minus 2 times C. Spacing between shafts should be greater than 1/8 in. and less than L minus .85 times the sum of the two bore diameters. To order complete couplings, specify coupling size with flange symbol (S) giving bore and keyseat. Refer to page F1—3 to order the required coupling. - 4 -
