FLENDER Standard Couplings
Flexible Couplings – BIPEX-S Series
General
■
Design
BIPEX-S couplings each comprise two hub parts connected by
a cam ring made of polyurethane (PU).
The couplings can be axially plugged in during assembly. The
hubs can be coupled to the shafts by many different methods in-
cluding set screws, key joint, slotted clamping hubs, half-shell
hubs, clamping hubs or expanding hubs.
BIPEX-S couplings are positive-locking and torsionally flexible
thanks to the polyurethane cam ring. Misalignment between the
connected shafts deforms the cam ring.
Coupling materials:
Hubs:
Up to size 38 aluminum
Sizes 42 and 48 steel
Cam ring:
PU 80 ShoreA -50 °C to +80 °C
PU 92 ShoreA -40 °C to +90 °C
PU 98 ShoreA
-30 °C to +90 °C
(standard ring)
PU 64 ShoreD -50 °C to +120 °C
The coupling types can be combined from the available range
of hub versions and different elastomer grades.
