Solve All Misalignment Challenges with A Single Beam Coupling

Ondrives.US single-beam spiral beam coupling for sale are precision-machined from solid aluminum and stainless steel billets for superior durability and corrosion resistance. Their design utilizes a single beam that spirals around the circumference of the coupling and penetrates through to the bore.

Single-beam spiral couplings can tolerate a greater amount of axial alignment than our 3-beam and 6-beam spiral couplings, and provide less torsional rigidity. They are our most cost-effective spiral beam coupling option.
