Slew Drive Solutions Smart Torque

As the leader in torque technology for solar and industrial applications, Kinematics has a reputation for producing the world’s most reliable slewing drives and components. We’ve earned that reputation through relentless innovation, research and development, product testing and validation — all focused on solving our customers’ biggest challenges.

Single Axis Slew Drives

Designed for solar trackers and a wide variety of industrial and manufacturing applications, KMI’s family of single-axis slewing drives deliver precise reliability. Featuring our patented hourglass worm technology, our gears allow for maximum gear contact, for greater strength and rotational torque.

Dual Axis Slew Drives

KMI’s dual-axis slewing drives provide rotational torque around two separate, independent axes, resulting in a wide range of motion with consistent and efficient precision. Applications include solar trackers, heliostats and concentrated photovoltaic (CPV), and satellite and radio dishes.


KMI provides customers with high-quality slew rings and gears that can be custom manufactured to accommodate specialized requirements. Applications include construction equipment, wastewater treatment machinery, mining, man lifts, truck cranes, dump trucks, utility equipment and more.
