Shrink Disc For Diaphragm Couplings

Hydraulic Shrink Disc

The Hydraulic Shrink Disc provides high integrity keyless fit joints using convenient, low cost slip-fit designs. Our design eliminates heat at assembly as well as keys, splines, and the need for plug/ring gauges. Shaft ends are simplified therefore reducing design, manufacturing and maintenance costs.

Slip-Fit Components

When used on a straight shaft, the Shrink Disc allows for infinite axial adjustment of the hubs position on the shaft eliminating the need for shimming the coupling length

Retrofit To Existing Hardware

In high power density applications, it is the total overhung moment that impacts rotor dynamics. The Shrink Disc allows for designs with smaller shafts and shorter interfaces which translates into reduced overhung moments.
