Using the Long Spacer Type Couplings in Stock
The following methods are available if the Long Spacer Type couplings in stock do not fit your equipment interface.
①
When the required Long Spacer is slightly longer than the
product in stock...
h
Use the long hub on both sides.
②
When the required long spacer is slightly shorter than the
product in stock...
h
Extend both shafts from the hubs.
The disk
’
s bore diameter can be made to fit the maximum shaft
diameter of either the standard or the long hub.
Single Plate Spacer Type
The NEF Series Single Plate Spacer Type reduces the distance between hub end faces (dimension
“
J
”
) and is suitable for applications where the
distance between shaft ends is short, or where the overall length must be shortened.
