Newly Re-designed P-Series Gearbox improves Backlash, Corrosion Resistance and Center Distance between Input and Outputs! 


Ondrives.US designs and engineers the best-performing, highest-quality couplings on the market today. Our 6-beam spiral beam couplings are specially engineered to simultaneously compensate for axial, angular, and radial (parallel) misalignment between shafts. Clamping and set screw models are available in a broad range of bore sizes and standard diameters. Order the spiral beam couplings you need, request a quote, or contact Ondrives.US for more information.


Highly Flexible Spiral Beam Couplings for All Misalignment Challenges

Ondrives.US’ six-beam couplings are precision machined from aluminum or stainless steel billets. Their designs incorporate two sets of three parallel beams, separated by a solid member. These beams are aligned 120° apart and spiral around the circumference of the coupling and penetrate through to the bore.

Our 6-beam spiral beam couplings are engineered to tolerate significant angular and radial shaft misalignment as well as slight axial movement.

Ondrives.US engineers have developed a White Paper “How to select Shaft Couplings” to assist you in the selection of the most appropriate shaft to shaft coupling for your application.
