Zero-Max Announces Performance Advantages For Its Servoflex Couplings Compared To Bellows And Jaw/Spider Couplings

Zero-Max announced that its Servoflex Couplings provide important reliability and misalignment advantages in servo motor, and stepper motor driven applications.
Demanding applications require a coupling that holds up to shock loads caused by rapid acceleration and deceleration, start/stop conditions, and torque reversals in these servo driven systems. According to Zero-Max testing and field experience, Servoflex Couplings provide the durability and reliability necessary for longer life and increased machine uptime in these applications compared to other coupling styles.

Servoflex Couplings Offer Increased Misalignment Capacity And Durability Advantages Over Bellows Couplings

“Misalignment between shafts on equipment exists in the form of angular, parallel (radial) and axial misalignment,” reports a Zero-Max spokesperson. “No matter how careful two shafts are aligned, they are never ‘perfectly’ aligned. Additional misalignment can also creep in over time from deflection due to torque loads and forces on the machine, machine wear, and eventual settling of the machine base. The Servoflex Coupling, within its ratings, handles these types of misalignments readily and easily.”

“The Servoflex Coupling’s misalignment advantage over bellows couplings will provide for a longer lifetime where the misalignment exists,” reports the Zero-Max spokesperson. “The reason is that, in most cases, the Servoflex Coupling is not as radially stiff as a bellows coupling which reduces the reaction loads on the connected components and stresses within the coupling itself. The Servoflex Coupling is designed to optimally handle torque, rotation, and misalignment simultaneously, thus providing longer life.”

Servoflex Couplings Have Lower Reaction Loads And Higher Durability Than Jaw/Spider Couplings

“Jaw/spider couplings do not perform as well as Servoflex Couplings in demanding applications,” reports the Zero-Max spokesperson. “The reason is that the coupling’s spider element can deteriorate over time from heat and fatigue, shortening its lifetime. Also, jaw/spider couplings experience torsional windup in higher torque applications and have longer settling times when stopping higher inertial loads. This results in increased cycle times and reduced machine throughput. The Servoflex Coupling’s misalignment capacity and high torsional stiffness avoids these issues.”

These benefits make the Zero-Max Servoflex Couplings a better choice over jaw/spider and bellows style couplings in many demanding applications. They have a sleek, compact, and robust design that performs reliably in 24/7 servo motor applications. Proof of the Servoflex Coupling’s superiority is in their operating specifications available online.
