This companion piece to the “Spiders are Key” article explains the difference between rubber-in-compression and rubber-in-shear coupling technology. It also offers an overview of the advantages of the rubber in compression technology for many applications.
An essential component of couplings, flexible elastomeric spiders transmit torque and accept misalignment. Design and material options for these flexible elements let you tailor them to the application.
Don’t order couplings by mechanical specifications alone; first be sure you’ve selected the correct type. This tutorial steers you through the different categories of couplings and spells out the capabilities of each type.
