Gear Reducer Spotlight: Shaft Mount Reducer

Shaft mounted speed reducers are commonly used in industrial applications where engines or electric motors are used to provide power for low shaft speed applications such as conveyors and hoists. Typically, AC motors run at approximately 1750 RPM, while the shaft speed of a conveyor may be only several revolutions per minute. Many types of […]

Inching Drives: Rarely Used, but Incredibly Important

Inching Drives Explained Inching drives are units that provide slow-speed operation of conveyor or elevator systems in order to facilitate maintenance and inspection. An inching drive, which contains its own gearbox reducer to achieve the slower speeds, can be installed between the driving motor and the main drive system, or it can connect to the […]


Factors for Choosing Coupling Systems for Large Loads

If you’re in an industry that involves large loads, such as mining, you most likely have special requirements when choosing a coupling system. Falk couplings offer a wide variety of options to address everything from weight to torque and misalignment. The most common types of Falk surplus couplings available include grid, gear, disc or elastomeric. […]


Falk Gearboxes and Other Gears In the Paper Industry

The paper manufacturing industry uses very large and heavy machinery requiring durable gears that can take on heavy loads. Falk gear reducers play an important role in successful operations due to their quality and reliability. Whether you choose new, rebuilt, used or surplus gear reducers, make sure your parts are dependable. Understanding the gears and […]


Explaining Gear Drive Quality Ratings

When purchasing surplus gear drives, it’s necessary to consider gear quality ratings in order to ensure your gear drive meets the requirements of your application. While the true test of a gear drive is its performance under operating conditions, failure to consider a gear’s rating can lead to major problems. Following is a look at […]


Backstops and Their Use In Power Transmissions

Whenever you’re transporting materials up an incline, such as on a graded conveyor, you’ve got the potential for disaster. If the power cuts out or your power transmission equipment goes kaput, you run the risk of damaged equipment and injured employees. That’s why a backstop is such an important mechanical power transmission product for applications […]


Power Transmission Equipment in the Mining Industry

Pulling materials out of the earth requires rugged power transmission equipment that delivers torque while withstanding heavy loads. When you look around any mining operation, regardless of the materials being extracted, you’ll see a diverse, complex array of gearboxes for the mining industry that are carefully selected to meet the needs of each task. You’ll […]


Fluid Couplings – Benefits & Performance

A fluid drive is a connector, or coupling, between a power source (usually an electric motor) and a piece of equipment or Falk gear drive. The main purpose of a Falk fluid coupling is to provide a smooth and controlled link between mechanical power transmission products and the specialized operating equipment they power. This link […]


Explaining Spiral Wound Gaskets

In any mechanical power transmission product, gaskets are used to protect the areas where two different surfaces join together. Gaskets provide a seal between the mating surfaces, cushioning them from each other and preventing erosion and leakage, which could ultimately necessitate an early gearbox repair. Spiral wound gaskets are one of the most commonly used […]
