Twin Disc

Founded in 1918 and headquartered in Racine, Wisconsin, Twin Disc, Inc. is a globally recognized leader in power transmission technologies — for land, marine, and industrial use. What began with innovation in agricultural clutches has grown into a broad portfolio of transmissions, clutches, PTOs, pump drives, torque converters, and control systems.

Over the decades, Twin Disc has expanded its capabilities through continuous engineering innovation, acquisitions, and global distribution. Their presence spans multiple continents, serving markets in marine, construction, mining, defense, and on/off-road trucking.

Product & Technology Offerings

Twin Disc’s product lines are engineered to handle high torque, heavy loads, and harsh operating environments. Their “on-land” product suite includes:

• Power-shift transmissions designed for heavy machinery and off-highway trucks — enabling smooth shifting under load
• Hydraulic and mechanical clutches / torque converters for transmitting torque efficiently and reliably under varying load conditions
• Power Take-Offs (PTOs) and pump drives for auxiliary equipment (cranes, dump bodies, pumps, etc.)
• Electronic control systems and hybrid / electric propulsion integration — reflecting their forward-looking engineering in electrification and system control

Their rigorous product testing and field validation ensure these systems deliver performance, durability, and low life-cycle cost in demanding environments.

Relevance for Truck & Heavy-Duty Applications

For truck parts distributors and service providers, Twin Disc components are widely used in vocational and off-highway truck applications. Their robust designs make them a strong choice for trucks in construction, mining, municipal service, refuse, and specialty equipment.

Key advantages of Twin Disc parts in heavy-duty truck settings include:

• High torque handling and durability in auxiliary drive systems
• Proven reliability under cyclical duty loads
• Parts availability and global support through distributor networks
• Integration with modern control systems, which helps in meeting emissions or automation needs

Twin Disc also maintains a catalog of replacement parts for their systems, supporting field repair and component-level maintenance in heavy equipment and truck fleets.
