    Torsional Element Specifications
    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
      Maximum Angular Misalignment:
    • Up to 3°
    Features
    Features 
    • Wide range of standard designs and materials
    • Application versatility
    • Shaft to shaft or flywheel to shaft designs
    • Designed to accommodate substantial shock loads, vibration, and misalignment
    • Low moment of inertia
    • Electrically insulating
    • No lubrication, maintenance free
    • Unique air-flow cooling design
    • Different element stiffness values allow for torsional tuning of applications with diesel engines
    • Economic design allows for cost effective solutions for torsional applications
    • Proven L-LOC spline-clamping hub virtually eliminates spline shaft profile wear and fretting
    • Oil, heat, and corrosion resistant elements (Hytrel®, Zytel®)
    • When used with S-bolts, the coupling can accommodate some end float
    • S-bolts accommodate applications requiring blind assembly
    • Model 6 unique spacer designs span gaps between equipment in excess of the normal equipment separation
    • Model 6 design available with bearings for high speeds and large amounts of equipment separation
    Notes
    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).
