Model Specifications

Model 2 and 2/SProvides a complete shaft-to-shaft coupling in a range of sizes for all industrial power transmission applications. It is similar to Model 1 shown above, 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.

Notes

For Hytrel, dynamic torsional stiffness values are non-linear with respect to torque. Value given is for 100% of nominal torque. Angular and parallel misalignment values are dependent on speed, and for rubber elements, should be adjusted according to figure 4. Hytrel® elements are only for applications where the driven component is piloted to the driver for SAE and DIN established alignments (i.e. Hydraulic pump flange-mounted to engine flywheel housing).Hytrel® elements are only for applications where the driven component is piloted to the driver for essentially perfect alignment (hydraulic pump flange-mounted to engine housing).

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° FMaximum Angular Misalignment: Up to 3°
