In power transmission, couplings are mechanical elements used to connect two drive elements together for the transfer of torque from one element to another. A coupling connects both elements, usually shafts that are in rotational movement, while also allowing a certain degree of misalignment, end movement, or both.

Couplings can be either rigid or flexible. Rigid couplings are more commonly used when two shafts are co-axial or lie on the same axis as each other. Flexible couplings are used where there is less chance of co-axiality or when shocks are likely to occur during transmission of torque.

In industrial machinery, couplings serve the following purposes:

  • To connect two shafts of separately manufactured units, for example, a motor and a generator.
  • To also allow for disconnection of the shafts for maintenance or repair operations or replacement of parts
  • To connect both the driving and the driven part.
  • Allow misalignment of the shafts and to reduce shock loads at the meeting point of both shafts

At SLS, we offer a broad variety of both rigid and flexible couplings for a variety of industries and applications:

  • Gear Coupling
  • Grid Coupling
  • Elastomeric Coupling
  • Disc Coupling
  • Fluid Coupling
  • Composite Coupling
  • Long Term Grease
