Elastomer Jaw Couplings TNS
Elastomer Jaw Couplings of the RINGFEDER® TNS series, formerly TSCHAN® TNS, combine compact dimensions with high resistance to breakage and effective shock and vibration damping in demanding industrial drives. The compression-loaded, oil-resistant intermediate ring made of Perbunan or polyurethane transmits torque in a fail-safe manner and compensates for axial, radial and angular shaft misalignments. Different shore hardnesses allow damping, torsional stiffness and transmission capacity to be precisely matched to the operating conditions. Typical applications include construction machinery, mining and ore extraction equipment, steel and cement plants, conveyor drives, and bridge, container and foundry cranes. The portfolio covers nominal torques of up to 13,500 Nm and includes standard and extended hubs, versions with brake drums or brake discs, radially removable jaw rings, and compact flange solutions. In suitable versions, the intermediate ring can be replaced without moving the connected machinery. This improves accessibility, simplifies installation and maintenance, and reduces downtime in highly loaded systems.
