About this file
This Technical Specification Sheet outlines a government requirement for a replacement coupling system for a 1409 compressor. The detailed specifications call for multiple precision-engineered components from Rexnord Inc., including three coupling hubs with 7.9946-inch bore diameters and 0.75-inch per foot taper, a center member assembly with specific dimensional requirements (17.507" length, 8.578" ID, 9.375" OD), two flex assemblies for a Rexnord coupling series 63, size 600, and one flex assembly to hub adapter flange.
A critical note emphasizes that two of the coupling hubs have slightly different mating flange sizes, with drawing numbers differing by only one digit, and vendors are instructed that obtaining both is crucial. Each component is to be fabricated according to specific Rexnord drawing numbers, with Quality Note 19 applying to all items. The technical specification provides precise measurements and references to ensure exact manufacturing specifications for the replacement compressor coupling system.
