Elastomer Jaw Couplings TNS | RINGFEDER®

The enormously powerful and resilient Elastomer Jaw Couplings of the RINGFEDER® TNS series – formerly known as TSCHAN® TNS – are the preferred choice of leading plant manufacturers and operators, especially in the field of highly demanding heavy-duty applications. These torsionally flexible and fail-safe quality couplings are optimally used e.g. as drive components in a wide variety of construction and building machinery as well as in steel, mining and cement plant technology, but also as connecting elements in overhead, container and casting cranes. They compensate for angular, radial and axial shaft misalignment within defined ranges and transmit the torque by means of pressure-loaded elastomers made of Perbunan or Polyurethane of different Shore hardnesses, which are connected to form an oil-resistant, vibration- and shock-damping intermediate ring. Due to their torsional elasticity, dangerous torsional vibrations from the operating range of the machinery are systematically shifted to speed ranges where no negative effects are to be expected. The Elastomer Couplings of the RINGFEDER® TNS series, manufactured to the highest quality standards, are extremely service-friendly, can be plugged axially and are applicable in any installation position and direction of rotation. They are available to customers in a wide variety of proven standard and individual special designs.
