Samiflex Couplings protect your equipment from costly downtime!

Now there’s a new solution to one of the most costly and troublesome problems facing maintenance personnel – coupling failure and the expensive downtime associated with fixing it. CDWdrives offers
maintenance-free elastomeric coupling solutions.


Coupling Insert RemovalCoupling insert is easily replaced without the need to move either driving or driven equipment.

A Samiflex Coupling has only four parts — Requires no bolts or nuts or special tools.

A polyurethane, axially split insert (item C) fits between two hubs (items A & B) so installation and removal can be achieved without moving hubs. A polyamide or steel retaining ring (item D) is installed over the insert securing both insert and ring between hubs.

Assembly & Disassembly

Once hubs (A) and (B) and retaining ring (D) have been installed and aligned on the shafts the coupling hubs will not have to be moved again during the life of the equipment. Elastic insert (C) is installed between parallel slots formed by the hub teeth. With the insert in position, slide the retaining ring (D) into position over the elastic insert.

Removing and replacing the coupling insert is easy and requires no special tools. By removing the retaining ring, the insert can be quickly and easily removed and replaced without the need to undo screws, bolts or other fasteners.

Samiflex Elastomeric Insert

The elastic insert is manufactured from a special blend of polyurethane and is available in three different compounds and three hardness ratings allowing the most appropriate insert to be selected for the application.

The standard (yellow) elastic insert is supplied at a 95 shore A. High- performance inserts type HD and HDT are colored brown and red respectively and enable torque ratings to be increased by 40% (consult CDWdrives).
