Additional Description



    The complete LF Series Model 2 is comprised of a cylindrical hub, a flanged hub, a base element, and hardware.The Model 2 provides a complete shaft-to-shaft coupling in a range of sizes for all industrial power transmission applications. It is similar to Model 1, except a flanged hub is added to make the shaft to shaft connection.Model 2/S allows the drive package to be “blind” connected. As with all S-Style models, axial end float of equipment shafts can be accommodated without harmful push-pull force.

Torsional Element Specifications
    There are two different rubber element materials available, High Temperature Rubber (HTR) and Neoprene (CR). Both elements are torsionally soft and are placed into compression during assembly. Rubber under compression can carry up to 5 times the amount of torque as non-compressed elements. The elements effectively accommodate shock, misalignment, and vibration plus minimize harmful radial and axial forces on the connected equipment. Neoprene (CR) is used in environments that are hostile to High Temperature Rubber (HTR).
    Available Durometer Hardness:
  • 50, 60 (Shore A scale)
    Operating Temperature Range:
  • HTR: -40° to 194° F
  • CR: -40° to 175° F
