Flexible Shaft Backing Assemblies

Flexible Backing Assemblies have the capability of a far greater shape adjustment range than conventional solid shaft backing assemblies.

Explore The Unique Design Advantages of Flexible Shaft Backing Assemblies

The design of Flexible Shaft Backing Assemblies allows for a significantly higher degree of offset between adjacent saddles. Because of this unique design, the mill now has the capability to dial in 1st, 2nd, 3rd, and 4th order shape control.

Because of our innovative technology, Sendzimir Inc. is able to set up Sendzimir mills for both the “M” and “W” shapes that provide better shape control during manufacturing processes. Furthermore, flexible shaft backing assemblies are able to either move that shape towards the center, or closer to the edge of the strip, thus allowing variable wave amplitude and the period of the mill, showcasing their wide range of production capability!

Of course, the segmented design allows for a combination of quarter buckle control and wedge offset.

Flex Backing assemblies are manufactured to the same demanding standards as conventional backing assemblies. Whereas the manufacturing process is different, the assemblies are capable of the same strength and durability as their conventional cousins.

Worldwide Renown

This type of shape control is unparalleled for the small work roll mill industry, which is why we have grown a customer base throughout Europe, Asia and Japan who are supplied with our flexible shaft backing assemblies! In fact, no other supplier of cluster mills outside of the T. Sendzimir, Inc family can guarantee the degree of shape control capability that comes with our standard-setting backing assemblies.

Flexible Shaft Backing Assemblies Provide “Flexible” Options

Segmented Backing Assemblies are designed to be torsionally rigid, yet can also bend dramatically at each saddle position. Replacing conventional backing assemblies with a flexible shaft backing design provides major improvement in theoretical flatness adjustability because of the way that it reduces stiffness. Our backing assemblies increase transverse flexibility relative to the traditional design and enable the crown profile, set by the shape of the backing shafts, to be transferred to the roll gap with minimum attenuation due to intermediate roll rigidity.
