GAM is a leading U.S. manufacturer specializing in a wide range of precision mechanical drive solutions for motion control and automation technology. 

About GAM

GAM Enterprises was established in 1990 by Gary Michalek, who recognized an opportunity to forge a lasting partnership with Jakob Antriebstechnik, a German company that introduced the pioneering servo bellows coupling to the automation market. Initially functioning as a distributor, GAM quickly grasped the need to incorporate manufacturing to achieve success. Consequently, 

GAM earned a reputation for prompt service and the ability to swiftly deliver customized bored couplings. In 1998, GAM Gear was founded by Craig Van den Avont, a former Chief Engineer at Rexroth Indramat, with the aim of establishing a high-precision gearbox company to complement GAM's servo coupling product line. These two entities merged in 2013, propelling the company's growth under Van den Avont's leadership. 

Over the years, GAM has transformed into a comprehensive manufacturing company, with many of its products designed and produced at its manufacturing plant in Mount Prospect, Illinois, thereby contributing to the resurgence of manufacturing in the United States. Currently, 90% of the gearboxes shipped by GAM are manufactured in the USA. Today, GAM is renowned for its wide range of products, adaptable manufacturing capabilities, and its ability to collaborate with customers in order to offer tailor-made solutions for their specific applications.

GAM Products

GAM offers a diverse product portfolio that includes robotic planetary gearboxes, inline and right-angle servo gear reducers, spiral bevel gear units, rack & pinion systems, servo couplings, linear mounting kits, and more.

Robotic Planetary Gearboxes

Robotic planetary gearboxes are a critical component in robotics, enabling smooth and precise movement. A robotic planetary gearbox consists of a central sun gear, multiple planet gears, and an outer ring gear. By leveraging the mechanical advantages of gear reduction, robotic planetary gearboxes offer improved torque, efficiency, and positioning accuracy, making them ideal for robotic applications in various industries such as manufacturing, logistics, and healthcare. The compact design and high power density of GAM's robotic planetary gearboxes make them an excellent choice for space-constrained applications, where reliability and durability are paramount.

Inline and Right-Angle Servo Gear Reducers

Inline and right-angle servo gear reducers play a crucial role in motion control systems by optimizing power transmission and torque output. These gear reducers are designed to interface with servo motors and convert the high-speed, low-torque motor output into low-speed, high-torque output, thereby enhancing system efficiency and performance. GAM's inline and right-angle servo gear reducers offer high torsional stiffness, low backlash, and precise motion control capabilities. They find extensive use in robotics, packaging machinery, material handling, and other applications where accurate and efficient motion control is essential.

Spiral Bevel Gear Units

Spiral bevel gear units are renowned for their versatility and ability to transmit power between intersecting shafts at various angles. They consist of spiral bevel gears that mesh at a 90-degree angle, allowing torque transfer with minimal loss. GAM's spiral bevel gear units are designed to deliver smooth and quiet operation while maintaining high efficiency. They are suitable for a wide range of applications, including machine tools, printing presses, and conveyors, where reliable and precise power transmission is critical.

Rack & Pinion Systems

Rack & pinion systems provide an efficient means of converting rotary motion into linear motion. They consist of a toothed rack and a mating pinion gear that engage to produce linear displacement. GAM's rack & pinion systems offer excellent positioning accuracy, high load-carrying capacity, and reliable operation. These systems find widespread use in CNC machines, automated cutting systems, and industrial automation equipment, enabling precise and controlled linear motion.

Servo Couplings

Servo couplings are essential components that connect the motor shaft to the driven load, ensuring precise and backlash-free power transmission. GAM's servo couplings are designed to accommodate misalignment, reduce vibration, and maintain system integrity. With various coupling types available, such as elastomers, metal bellows, and disc couplings, GAM offers versatile solutions suitable for different motion control applications. These couplings contribute to improved system performance, reduced wear on components, and extended equipment lifespan.

Linear Mounting Kits

Linear mounting kits provide a convenient solution for installing and aligning linear motion components such as actuators and slides. GAM's linear mounting kits simplify the integration process, offering pre-engineered solutions that save time and effort. These kits include everything required for proper installation, including parallel mount kits, linear side mount kits, and hollow output gearboxes. By ensuring accurate alignment and reducing assembly complexity, GAM's linear mounting kits contribute to efficient and reliable linear motion systems.
