Advantages:

• Protects shaft-support bearings by exerting consistently low reactive forces, even under large misalignments
• Homokinetic transmission - driving and driven shafts rotate at exactly the same speed at all times
• Zero backlash and high torsional stiffness
• Electrical insulation
• Accommodates moderate radial misalignment in a short length
• Accommodates relatively large axial misalignment
• Easy installation in blind or difficult installations - all block couplings have through bores
• Inexpensive replaceable wear element
• Internal grease reservoir provides continuous flow of lubrication driven by centrifugal force, allowing coupling to survive harsh, dirty environments
• Somewhat "failsafe", in the sense that the driving hub will continue to turn the driven hub after failure of the midsection

• Accommodates a relatively small angular misalignment
• No mechanical "fuse" feature - unlike standard Oldham designs, under overload, all subcomponents of this coupling must be replaced, rather than one inexpensive wear element

Advantages of OEP's Block Coupling over other manufacturers' couplings with similar designs:

• This configuration is not offered by many coupling manufacturers, and those who do offer only a very limited selection of sizes and materials compared to OEP
• Higher torsional stiffness, longer service life, and more consistent performance from one coupling to another due to much tighter machining tolerances, 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
