Hydrostatic Spherical Couplings


Team Corporation's Hydrostatic Spherical Couplings transmit tensile and compressive forces while allowing angular misalignment. Hydrostatic Spherical Couplings are used in applications for multi-axis vibration, structural fatigue testing, and any application where angular movement is required. Each coupling connects the vibration system (Hydraulic or Electrodynamic) to the table / test article, protecting the system from damage due to misalignment or angular motion.

Single and Double pivot couplings are available, in either 0.5 degree or 6 degree configurations. Our double pivot couplings allow for angular and lateral misalignment. Each spherical surface is hydrostatically lubricated for extremely high stiffness, zero backlash, and infinite life.
