Mechanical Power Transmission

Main Content

Mechanical power transmission products are essential elements that transmit power from one component to another in machines and systems. These components are used to transfer motion and power from a prime mover, such as an electric motor or engine, to other components, such as shafts, bearings and machines.

Weimer Bearing’s mechanical power transmission products range from couplings, sprockets, chain, gearing, reducers and other drive components. View our full line of mechanical power transmission products and manufacturers below.

Our mechanical power transmission products are utilized in nearly every industry, including manufacturing, automotive, aggregate, machinery, oil and gas, power generation, construction equipment, robotics, distribution centers, food and beverage, pharmaceutical, medical and agriculture. We stock a full line of power transmission components at our locations to keep your operations running smoothly with little downtime.
