Materials for midsection: Delrin – for general use; low friction, long wear. High-temperature high-performance thermoplastic; for high-temperature or for more demanding applications.
Materials for hub: Alloy 360 brass, alloy 2011 aluminum, and alloy 303 stainless steel
Shaft attachment options: Set screw without keyway, set screw with keyway, clamping without keyway, clamping with keyway
Torque-limiting option – as detailed in this Case Study, we offer midsections that will break cleanly at a torque specified by the customer, as a replacement for other conventional, more costly torque-limiting devices
Advantages of OEP Couplings’ Oldham configurations over those of other manufacturers:
Higher torsional stiffness, longer service life, and more consistent performance from one coupling to another due to tighter machining tolerances and better surface finishes
Higher static break torque and higher peak torque due to small but critical geometrical features, details of fabrication techniques, and the use of advanced materials and processes
Higher RPM rating because of dynamic balance inherent in every coupling
