Slit Beam Couplings

A helical or slit beam coupling is a one-piece coupling that uses multiple machined straight cuts penetrating from the outside diameter to the bore. These helical beam couplings are designed to transmit torque between two shafts while still compensating for the shaft to shaft misalignments. Use these zero-backlash shaft couplings in high-speed applications where you need to reduce residual stress.

Slit Beam Coupling Applications and Selection Criteria

Slit beam couplings are frequently used for low torque applications. The versatile design of helical flexible shaft couplings makes them ideal for a range of applications, including machine tools, encoders, pumps, instrumentation, and other motion control applications.
The size, material, and style of your helical flexible shaft coupling ultimately depend on what the coupling will be used for. As the number of stars in the slit beam coupling increase, the torsional stiffness increases, as well as the angular and parallel misalignment capabilities.

Benefits of Using Aluminum for Slit Beam Couplings

Aluminum is the most common material choice for beam couplings because it has the best mix of attributes for the most common beam coupling applications. This material is not only lightweight but has an excellent strength-to-weight ratio, making it ideal for motion control applications.
Additional benefits of aluminum for helical beam couplings include:
  • Lightweight for low inertia
  • High level of responsiveness
  • Fatigue Resistance
  • Long, service-free life
  • Electrolytic finish for added durability and corrosion resistance
