TS4 beam coupling

A beam coupling, also known as helical coupling, is a flexible coupling for transmitting torque between two shafts while allowing for angular misalignment, parallel offset and even axial motion, of one shaft relative to the other.

  • Description
  • A beam coupling, also known as helical coupling, is a flexible coupling for transmitting torque between two shafts while allowing for angular misalignment, parallel offset and even axial motion, of one shaft relative to the other. This design utilizes a single piece of material and becomes flexible by removal of material along a spiral path resulting in a curved flexible beam of helical shape. Since it is made from a single piece of material, the Beam Style coupling does not exhibit the backlash found in some multi-piece couplings. Another advantage of being an all machined coupling is the possibility to incorporate features into the final product while still keep the single piece integrity.

    Features of TS4 beam coupling:

    1.One-piece metallic beam coupling 

    2.Zero backlash

    3.Absorb parallel,angular and axial misalignments

    4.Identical clockwise and anticlockwise rotational characteristics

    5.Material:Aluminum alloy and stainless steel

    6.Set screw type
