Samiflex Couplings and Inserts

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 virtually maintenance-free Samiflex elastomeric couplings and inserts that not only reduce premature failure but are also very cost-effective.

A Samiflex Coupling only has 4 parts: 2 cast iron or steel hubs, 1 precision cast polyurethane insert, and 1 retaining ring from either polyamide or steel. Assembly is simple and doesn’t require any nuts and bolts or special tools.

Assembly & Disassembly

Align hubs (A) and (B) on the shafts. Insert the elastic insert (C) into the parallel slots formed between hubs (A & B). Slide a polyamide or steel retaining ring (item D) over the insert securing both insert and ring between the hubs. Retaining rings are provided with locking screws as standard.

Once the hubs (A) and (B) have been installed and aligned on the shafts, the coupling hubs will not have to be moved again during the life of the equipment. The insert is quickly and easily removed and replaced without the need to undo screws, bolts, or other fasteners by simply removing the retaining ring (D).

Advantages

Easy installation: Changing out a Samiflex elastic coupling is simpler and easier than any other type of coupling. The axially split coupling inserts design allows for the removal and replacement of inserts without the need to move either driving or driven equipment. No special tools are required.

Maintenance-free: No lubrication is required over the life of the insert.

Inspection and service made easy: Hubs can be rotated independently so there is no hub wear and the direction of rotation can be checked before full assembly. The coupling hubs do not mesh together causing metal-to-metal contact resulting in excessive wear. Inspection and replacement of a Samiflex coupling inert can be done in seconds by simply moving the retaining ring to one side to access, view, and replace the insert. Another advantage to using a Samiflex coupling is that when the insert is removed the driven machine is isolated for easier maintenance.

Long-lasting: On average inserts last 25,000 working hours (3yrs). Inserts are not affected by UV light and do not degrade like rubber inserts, therefore they have a longer operational life and an indefinite shelf life.

Durable: The inserts are individually cast from a special blend of polyurethane, that is baked & cured. This process ensures the integrity of the insert is not compromised and the performance remains high. Polyurethane inserts are very resistant to corrosive and chemical attacks.

Small to large torque: Applications from double digits up to 200,000 Nm torque are available with shaft dimensions ranging from Ø8mm to Ø300 mm. Polyurethane insert hardness options are available to optimize torque capacity and damping.

Versatile: Both horizontal and vertical operation is possible with the standard coupling. SAE flywheel and custom mounting arrangements are also available.

Inserts available for every application and environment: Increased performance can be achieved using one of the several types of inserts. Samiflex inserts are manufactured from a special blend of polyurethane and are available in three styles of compounds and three hardness ratings allowing the most appropriate insert to be selected for an application. Different Polyurethane insert hardnesses are available to optimize torque capacity and damping. The standard insert can handle a large temperature range from -40 to 80°C (-40 to 180°F). High-temperature inserts are available up to 150°C (300°F).

Samiflex Elastomeric Insert

Samiflex elastic inserts are available in several special blends of polyurethanes, three styles of compounds, and three hardness ratings allowing the most appropriate insert to be selected for your application. (Consult CDWdrives for sizing and selection)

The standard (Yellow) elastic insert is supplied at 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).
