The HRC Coupling Series consists of highly resilient couplings which are produced in three series. The 80 Series allows for maximum angular, radial, and axial misalignment while the 81 Series and 82 Series offer spherical and roller bearings that allow for greater capacities.



Our Clutch and Coupling company manufactures two series of clutches. The TB Series is designed for exceptionally high torque applications and the TR Series is a torsionally resilient line of clutches which adds significant dampening for torsional vibrations.
