BELLOWS COUPLINGS

When ordering a certain type of membrane coupling, please use the following signification:

SS X/X X X/X X

 

SS _/_ _ _/_ _

Bellows coupling

__ X/X _ _/_ _

Outer diameter, and length of coupling D/L, (mm)

__ _/_ X _/_ _

Nominal turning moment

__ _ _/_ _ X/X _

Diameters of the connection holes d1/d2, mm

__ _ _/_ _ _/_ X

Connection of the flanges to the shafts:

   A by means of seat screws

   B by means of collets

   C by other means

Bellows Couplings

SS 16/26 X X/X B

Characteristic features:
. Smaller torsional resistance.
. Greater elasticity relative to axial, radial and angular displacements of
shafts.
. Small dimensions.
. Small weight.
. Ease to assembly.
