Roller Chain Coupling

CouplingsTsubaki is a leading provider of dependable, high-quality power transmission products for customers worldwide. With more than 100 years in the power transmission industry, we are committed to the ongoing development and advancement of our products and services. Our focus on innovation is reflected in our continuously upgraded and modernized facilities, which allow us to meet the evolving needs of the market. Our state-of-the-art power transmission technology includes a selection of roller chain couplings that are ideal for a broad range of coupling applications. Our chain couplings are engineered to excel in any application you need, with exceptional flexibility, strength, and a surprisingly simple assembly.


A roller chain coupling is a mechanical device composed of a double-strand roller chain and two modified sprockets. The design is simple and highly effective, despite its small size, and is composed of a robust chain and specially cut, hardened-tooth sprockets that allow a high amount of torque to be transmitted.

Our unique single-pin connection design, available only from Tsubaki, makes installation and handling of a roller chain coupling simple. The single-pin design allows the chain to be uninstalled and reinstalled quickly and efficiently, reducing labor needs and minimizing downtime.

Benefits of Tsubaki's Roller Chain Couplings

In a roller chain coupling, torque is distributed across the combined mating surfaces of each of the chain and sprocket pitches, which allows the coupling to handle a high amount of torque for its size. The chain connects closely with the sprockets, for a highly compact and lightweight coupling that transmits torque with the utmost efficiency.

Our compact roller chain couplings are housed in an aluminum casing that clamps to the sprocket hubs and rotates with the body of the coupling without the need for bolts or other projections. The coupling chain itself is easy to install and remove using a single connecting pin, so you save on installation labor and downtime.

When working with shafts in a drive, traditional rigid couplings require extremely precise alignment between the coupled shafts. Roller chain couplings introduce much-needed flexibility with clearances both in the chain and between the chain and sprocket teeth. With this added mobility, even with minor misalignment, chain couplings can operate in a smooth and responsive manner, reducing the potential for overheating and wear common in more rigid coupling designs. The operation of roller chain couplings is less affected by unavoidable shaft expansion and contraction.  The flexibility and easy alignment of the drive shafts, when using chain couplings, will save time and money on equipment repairs and replacements.

Tsubaki’s exclusive roller chain coupling design is engineered to keep production lines up and running. Our specialized dual-strand roller chain features a single-pin connector for exceptionally easy installation. We use only the highest quality materials for our precision hardened sprockets and dual set-screws to lock your system in place. The ease of installation, coupled with the exceptional strength of the roller chain and sprocket components, make Tsubaki’s roller chain couplings ideal for almost any power transmission application.


CouplingsTsubaki’s roller chain coupling features a unique single-pin design that simplifies the installation process substantially. Simply follow these easy steps:

  1. Install oil seal to each hub
  2. Adjust the alignment of the shafts and coupling components
  3. Adjust the distance between the sprocket faces
  4. Thoroughly lubricate the coupling chain
  5. Install chain to couplings using single-pin connecting link
  6. Firmly close and fasten the cover of the coupling (optional, depending on operating conditions)

Overall, the installation process for Tsubaki’s roller chain couplings is significantly simpler and quicker than traditional rigid shaft couplings.


To ensure optimal operation of low- or medium-speed, high-torque transmission applications, install Tsubaki’s roller chain couplings. At Tsubaki, we pride ourselves on providing the latest in power transmission technology. Our broad global presence allows us to serve customers almost anywhere in the world quickly and effectively.
