Power Transmission Couplings Elastic Jaw

Spider couplings are torsionally flexible and designed for positive torque transmission, and they are generally fail-safe. Operational vibrations and shocks are efficiently dampened and reduced. Two congruent coupling halves with concave claws on the inside are peripherally offset in relation to one another by half a pitch. They are designed to enable an involute spider to be located between them. These couplings are capable of compensating for axial, radial and angular displacements of the shafts that are connected. Straight boss design type.
