ServoClass Couplings are often described as very smooth and quiet during operation. That smooth operating characteristic is a result of several factors, including how consistent the various parts of the coupling are assembled and held together. Maintaining precise and repeatable assemblies is more than having a good torque wrench.  For example, it is possible to have several bolts that are all torqued to the same value and still have inconsistent clamping forces.  This situation would be caused by an inconsistent coefficient of friction in the threaded surfaces.

To ensure that each and every ServoClass coupling is assembled correctly and will grip the shaft precisely, Zero-Max uses a special solid film lubricant treatment on the threads of all the socket head cap screws used in the ServoClass line of couplings.  It is this attention to even the smallest details that makes the ServoClass couplings run smooth and perform at the highest level in applications of any speed.

Additional design features of this product line include all high quality materials including precise 304 stainless steel disc members. These are aligned and locked precisely into position onto the high strength aluminum alloy hubs with ISO 4762 XL 12.9 corrosion resistant socket head cap screws. The coupling assembly process itself is also controlled with a computerized system for the most precise fit of all components.

Zero-Max ServoClass couplings are suitable for precise positioning requirements and high speed reversing loads common of many AC and DC servo motor systems. These applications include automation of all types, packaging, semi-conductor assembly, laboratory automation and medical equipment, to name just a few. They are designed to provide superior shaft engagement and reliable use with system speeds up to 10,000 rpm.  Further, the coupling’s increased clamping strength eliminates the need for keyways while providing a clean, balanced design.

Available in 12 sizes with both single and double disc models, ServoClass couplings handle torque ratings ranging from 0.5 to 250 Nm. The ServoClass couplings can also accommodate parallel (radial), axial, and angular misalignments. All ServoClass coupling models are manufactured of RoHS compliant materials.
