Product description

FK 7 DMS - Double laminar retaining rings

for shafts (with centrifugal force protection)

Application “FK7 DMS” Double retaining ring shaft with centrifugal force protection

“FK7 DMS” double laminar retaining rings with centrifugal force protection can be used for rotational speeds that cannot be achieved by “FK7 DSW” retaining rings.

Diameter range for DMS rings:

Ø 45 mm to Ø 310 mm.

Ring materials

Axial stress:

Shearing tests under operating conditions must be performed to determine the axial shearing capacity of the retaining rings. The secure position of the retaining rings in the groove cannot be guaranteed if the surrounding components thrust uncontrollable against the laminar rings during operation (coupling effect) or if the components vibrate extremely.

Order information:

The ring diameter information must match the housing or bore diameter dimensions “D1″ for all inquiries and/or orders.

Run and installation tests::

Run and installation tests under operating conditions must be performed in each case before standard production of our laminar rings can begin to determine whether the desired sealing effects can be achieved.
