High-quality RINGFEDER® Barrel Couplings of the TNK series are used in cranes and hoists to optimally connect the drive shaft of the gearbox with the rope drum. Further areas of application are lifting platforms, platform hoists and winch conveyors of all kinds. RINGFEDER® barrel couplings are torsionally rigid, easy to assemble and maintain and effectively compensate for axial and radial shaft misalignments. They offer friction-fit torque transmission via hardened steel barrel rollers that fit into semicircular, machined openings on the hub and sleeve and thus ensure safe and reliable bearing of occurring bending loads and radial forces. Integrated inner and outer covers in conjunction with lip seals prevent foreign objects from penetrating and lubricants from escaping.
