Misalignment, shock loads, and vibration not only slow equipment down, but they can destroy it. FallLine's cast polyurethane couplings take that punishment, transmitting torque reliably while protecting the drive systems around them. Unlike rubber, which degrades, or metal, which transfers every shock downstream, our custom urethane couplings flex where it counts and hold firm where it matters. From high-cycle industrial machinery to precision OEM applications, FallLine custom-formulates every coupling to the exact demands of your environment for mid-volume production and large-scale manufacturing.

FallLine manufactures cast polyurethane couplings across a wide range of durometers and configurations. This includes jaw and spider couplings, as well as torsional and compression-loaded designs. Our in-house chemists and engineers select and formulate the right urethane compound for your specific torque requirements, operating temperatures, and shaft misalignment tolerances to ensure every coupling performs exactly as your application demands.
Custom Urethane Couplings That Absorb What Metal and Rubber Can’t
FallLine custom-formulates urethane couplings with exceptional abrasion, impact, tear, and chemical resistance built in, giving you a component that fights back against the conditions that destroy rubber and metal.
Our polyurethane flexible couplings resist ozone, sunlight, oils, and chemicals while holding dimensional accuracy across a broad temperature range.
In-house CNC tooling puts tight tolerances within reach on every order.
Why Engineers Choose Polyurethane Flexible Couplings Over Rubber and Steel
Rubber wears out, while steel transmits every shock straight through. Polyurethane flexible couplings do neither. Engineers across industrial manufacturing and OEM applications consistently choose cast polyurethane couplings because they absorb vibration, resist chemical and environmental degradation, and outlast both alternatives, all without sacrificing dimensional accuracy or torque performance. The result is less downtime, longer equipment life, and a lower total cost of ownership.

FallLine produces cast polyurethane couplings across a wide range of durometers, from soft, flexible formulations to harder, load-bearing compounds.
Yes. We can reverse-engineer custom urethane couplings from a sample part or technical drawing and move directly into production-scale manufacturing.
The teeth and flex elements of a polyurethane flexible coupling naturally compensate for angular and parallel shaft misalignment, protecting connected equipment without sacrificing torque transmission.
