Knitted wire spider used in high-temperature shaft couplings

As with the Rotex couplings incorporating elastomeric spiders, those with knitted stainless steel wire spiders provide vibration dampening and a fail-safe operating characteristic. When operating at up to 180degC, torque capacity, torsional stiffness and damping remain substantially unchanged. Above 180degC the operating characteristics of the knitted wire spider vary slightly, but the component can be specified for applications in which temperatures up to 250degC are encountered.

Other notable features are the non-corrosive and electrically conductive material properties, both of which can be advantageous in some applications.
