Product Description
BKC-TF Series Metal Bellows Couplings provide the ideal complement to Magtrol’s TF Series Torque Flange Sensors, when mounted in a drive train.
The torque transmission element consists of a metal bellows, clamping hubs for shaft ends and a flange element to connect with the TF Sensor. The couplings are both torsionally stiff and flexible in order to compensate for axial, angular and radial misalignment. The high torsional spring rate of the couplings ensures a high torsional stiffness and angular precision.
Design & Material
Bellows are made of highly flexible high-grade stainless steel. The hub material is made of aluminum stainless steel.
Use of an ISO 4762 radial clamping screw is required for clamping.
