Rigid Couplings

We’ve partnered with Climax Metal Products to review one of the most simple and cost effective couplings, the rigid coupling. If your application is in need of zero backlash and shafts are aligned, then rigid couplings are a highly recommended component. They are used for aligning and joining shafts at lower speeds and torque. Compact and economical rigid couplings come in a variety of designs based on your application needs.

Rigid coupling materials:

  • Steel with Black Oxide Finish
  • 303 Stainless Steel
  • Aluminum

Application examples:

  • Food processing equipment
  • Conveyors
  • Medical Indexing
  • X-Ray Machines
  • Automatic Doors

Types of Rigid Couplings

Set Screw

Set screw couplings are the most common and cost-effective rigid coupling designs. They hold the shaft via set screws that are intruded onto the surface of the shaft. This is the holding power. Depending on the manufacturer, there could be 2 – 4 set screws for different holding power. For example, Climax Metal Products has designs with both 2 and 4 set screws. One of the drawbacks of this design is that the set screws could damage the shaft. In order to replace the coupling, disassembly is required of the shaft components. They can also be designed with or without a keyway.

One-Piece

One-piece rigid couplings are designed with 4 socket head cap screws which allows for more holding power. With this design, the shaft is not damaged by the screws. In order to replace the coupling, disassembly is required of the shaft components. They can also handle higher axial load and torque capacity.

Two-Piece

Designed with 8 socket head cap screws, two-piece rigid couplings have even more holding power. This allows for easier replacement of the coupling in which you don’t have to disassemble many shaft components to install or remove the coupling. Two-piece rigid couplings are able to handle higher axial load and torque capacity.

MISUMI has a variety of couplings that you can explore. To view MISUMI’s selection of Climax Metal Products rigid couplings, visit the product listing at this link.
