Description
John Crane A Series couplings provide a solution to one of the most persistent and troublesome problems facing maintenance personnel: periodic coupling failure and the downtime and expenses that go with it. If a new insert is needed, a replacement can be installed in minutes, without moving either the prime mover or the driven equipment.
The A Series is the simplest construction of all our couplings. The design is compact and fully conforms with both ANSI & ISO requirements. The arrangement consists of a close-coupled hub and a spacer hub. One end of the spacer piece has six or eight teeth, depending on size with the other end flanged. All of these components are made of quality carbon steel. The split insert, which is made of specially compounded urethane, fits over the hub/ spacer teeth. The retaining ring is made of steel, and is located with two setscrews. Bolts are supplied to assemble the spacer-to-spacer hub and a specially formed thread used to lock and retain.
