Element, Spidex coupling, 92 Shore A (Yellow), 65, 625 Nm, 4250 RPM, Lovejoy.

The spider coupling element gives reliable, smooth power transmission without torsional oscillation / vibration and so protects the connected machinery. Due to the complete flexibility and ductility of the elastomer ring, it compensates for parallel and angular displacements as well as to absorb longitudinal movement of the shafts. The involute teeth of the elastomeric inserts are crowned in order to avoid edge pressure on the tooth flanks and so avoid undesirable axial thrust.
