Coupling Specs: jaw_spider
Mechanical shaft coupling specifications for rotating equipment design. Covers 9 coupling types (jaw/spider, gear, disc/diaphragm, grid, Oldham, bellows, fluid, universal joint, rigid flange) in small/medium/large/extra-large size classes. Includes bore range, maximum torque, maximum speed, angular/parallel/axial misalignment limits, torsional stiffness, damping capability, service temperature range, maintenance requirements, typical applications, advantages, and limitations. Data from Rexnord Falk, Lovejoy/Timken, Thomas, Voith, Spicer/Dana catalogs and Shigley's handbook.
