A flexible jaw coupling is a positive, torsionally flexible coupling which

also permits radial, axial and angular displacements between the

driving and driven parts. It is failsafe.

Two coupling halves with concave claws are located opposite each

other, offset circumferentially by half a pitch division. An involute

elastomeric with crowned tooth profile is located in the space between

the claws.

The spider insert is extremely wear resistant, to oil, ozone and

ageing, and notable for its resistance to tropical conditions. The high

internal damping protects the drive motor from dynamic overload.

At an operating temperature of -30 °C to +80 °C (-22 °F to +175 °F)

[including short term temperature peaks up to +120 °C (248 °F)],

perfect operation is guaranteed.
